Alongside House Martins and Swallows, Swifts are losing suitable nesting habitat at an alarming rate. Through changes to roof design and structure, nesting sites are becoming increasingly rare. This has contributed to the widespread decline of this species which has seen them added to the UK Red list.
Swifts return to Britain and Ireland from April, following a lengthy flight from Africa. Before leaving in August, Swifts must mate, lay and incubate their eggs. Nest boxes provide Swift colonies with the perfect site to raise their young – boxes should ideally have a large internal cavity with an elongated entrance hole, either at the bottom or downward facing. Swift nest boxes should be placed under the eaves of a building, on walls at least five metres in height. Since these birds nest in colonies, multiple nest boxes or boxes on neighboring houses are ideal for attracting more Swifts.
Here, we look at a selection of nest boxes suitable for Swifts, highlighting the benefits of each design.
Key materials
Wooden nest boxes are preferred by many. This lightweight material is breathable and provides excellent insulation for nesting birds, helping to protect them from temperature extremes between seasons. Typically used for external boxes, harder wood types provide a fair level of robustness and longevity when at least 15mm thick and help to prevent predator access to the nest. The main drawback of wooden nests is the maintenance they require – they should be monitored to ensure the wood remains in good condition, and care taken in choosing wood treatments as many can be harmful to nesting birds.
WoodStone and Woodcrete are almost identical in composition, but Woodcrete is a patented material by Durisol. The material is made from a blend of wood and concrete to produce long-lasting, very durable boxes which can last for decades. It has good insulative properties and creates a thermally stable environment inside the box to shelter inhabitants from extreme temperatures. This material is offered for both built-in and mounted nest boxes but is more often used for built-in boxes due to its weight, which is heavier than wood or eco-plastic. WoodStone is typically more expensive than other materials and requires thoughtful design to improve ventilation to prevent the buildup of moisture in the nest.
Certain components of a bird box may be made with eco-, or regular, plastic. A low-cost option, plastic is more lightweight than Woodcrete, and provides more longevity than wood. This weather resistant material is easy to maintain and is often sourced from recycled plastics. Nest boxes featuring eco-plastic require careful design to mitigate issues with insulation and ventilation. This material is, however, less durable and provides little resistance to predators or extreme temperatures.
This built-in box provides Swifts with a thermally stable, secure nesting space. Woodstone is a durable, long-lasting material that is perfect for new builds.Because it is constructed to standard brick dimensions, this nest box can be rendered over to better blend into constructed walls.
This box provides nesting birds with ample nesting space in a single internal cavity. Woodstone material improves the thermal stability and longevity of the box, while maintaining breathability. This build-in box is also suitable for sparrows, Starlings and other small urban birds.
This built-in box from Unitura is designed to be mounted in eaves and soffits and features a sloped nesting board to allow for mounting at multiple angles. The box has one wood-concrete entrance for extra durability, and a durable plywood box for longevity. This nest box has two nesting bowls to encourage colony nesting.
Designed to be incorporated into new builds or renovated properties, this Swift brick comes in three colours to ensure discreet placement. Constructed from brick, this box will be durable and will last for many years.
Made with insulating concrete, this nesting box provides a long-lasting, discrete, internal nesting space for Swifts. It can last for decades in the right environment. This box can also be bought unfaced, allowing it to be rendered to match the building’s aesthetics.
This robust nest box is constructed entirely of woodstone, ensuring a long-lasting, enduring design and thermal stability throughout the year. A rear entrance provides easy access for cleaning, and a downward facing entrance hole discourages other small garden birds from occupying the nesting space.
This nest box has a single cavity for nesting Swifts and an elongated entrance hole. The wood–concrete material ensures a climactically stable, long-lasting environment for generations of Swifts and a sloped roof ensures adequate drainage.
This robust nest box provides a single compartment for nesting Swifts, with excellent insulation for stability in extreme temperatures. An oval entrance hole and sloping roofs help to exclude Starlings and encourage Swift settlement. Designed to be placed under eaves, the mounting plates and openings are on the sides to allow close-fitting insulation.
Available with left and right-hand side entrances, this box provides nesting Swifts with an underside entrance and landing ramp for easy access. The wood construction is naturally fungal and insect repellent and provides nesting birds with a well-insulated, stable environment.
A hybrid box designed to house both Swifts and bats, the Kiki nesting box provides a thermally-resistant environment suitable for both groups. The compartment that is allocated for Swift nesting has a forward-facing entrance. The durable, long-lasting design can have a lifespan up to 25 years.
Constructed with an upcycled material made from recycled waste insulation, this double-chambered swift box is 100% resistant to moisture and has a long lifespan of up to 25 years. It is lightweight and simple to construct, making it a worthy addition to an existing structure. The excellent thermal properties, and downward-facing entrance, make this an attractive nesting choice for visiting Swifts.
An unobtrusive nest box, the Manthorpe Swift Brick provides nesting birds with a long-lasting, secure nesting site. This nest box is designed to sit inside the insulation cavity of a building, helping to create a thermally stable environment. This brick is available in six colours to blend into existing brickwork.
This droppings board prevents the accumulation of droppings from Swift nest boxes around windows and doors. It can be easily assembled and installed using screws and is suitable for use beneath any nest box.

Modern infrastructure has come with a host of changes to roof design, which have impacted the availability of suitable nesting sites for a number of avian species. House Martins and Swallows have been particularly affected by these changes, and we can encourage their colonisation, nesting and breeding through the provision of artificial habitats.
These birds live in colonies of around five nests constructed using spring mud, but in drier springs this can be in short supply. Gathering building materials also requires significant energy expenditure for breeding birds, removing energy available for roosting and raising young. Nest boxes provide a ready–made habitat suitable for nesting without spring mud availability.
Swallows and House Martins require a cup or bowl-shaped nest, with a small, narrow entrance and are generally made of Woodcrete/WoodStone or hard wood. They are typically placed under the external eaves of a building to mimic natural nesting locations and are best placed on a sheltered side at a minimum height of 2m above the ground. Due to their natural nesting habits, House Martin and Swallow nests are designed to be wall mounted. These birds are highly sociable and prefer to nest in colonies, so consider mounting multiple nests to further support natural behaviour.
Here we look at a selection of nest boxes suitable for House Martins and Swallows, highlighting the benefits of each design.

This book (or rather book series, since it will be more than just one book) has been an incredibly long time in the making, and the sheer scale of the project alone makes it a huge achievement. What were the main challenges you came across and how were they overcome?
Our project began in 1998 when the French publisher Delachaux et Niestlé requested us to create a new feather identification guide based on colour photos. The illustrations of feathers in our Atlas are arranged according to a unique, recognisable pattern on astandardised grey background, each of them depicting the feathers of an individual bird, which allows readers to grasp the essence of different feather types at a glance. We use a method of directly scanning feathers on a flatbed scanner that was developed at the University of Amsterdam. But printing costs were prohibitive. Print-on-demand technology made it possible to produce smaller, more affordable print runs. We used this technology to produce our first collective work of the Feather Research Group titledThe Tail Feathers of the Birds of Central Europe. We also produced two feather calendars with a series of colour plates that were composed for our Atlas of Feathers for Western Palearctic Birds as a test run to see how the colours came out in print.
In 2009, after 10 years of intense work, we produced a DVD with 1,280 colour plates featuring illustrations of feathers for 330 Passerine species. This compilation from many sources resulted in a wave of interest in our project. Meanwhile, the number of Passerine species for which colour plates were ready had nearly doubled to more than 600 species. We decided to publish our collective work under the name The Featherguide rather than any individual names. In this way, everyone in our group can identify with this eponym and no one needs to feel that anyone is adorning themselves with borrowed plumes.

The most time-consuming aspect of our work is the composition of feather images for bird species that are not found in any feather collections. Thanks to the kind support of the Feather Identification Laboratory at the Smithsonian Institution, and generous curators at Natural History Museums, it was possible to develop a technique that allows us to extract depictions of isolated feathers from photographs of bird skins. The missing part of the feather that remains in the skin is digitally added in a seamless way. A single colour plate produced in this way from many different puzzle pieces takes up to one week. With 1,350 bird species to be covered in our Atlas and our goal of illustrating all important plumages, you can imagine how many months and years this adds up to. We thank readers for their patience and interest.
Our project has inspired a number of off-shoots that will be welcome by most readers. For example, the French feather identification book by Cloé Fraigneau, which is now available under the titleAn Identification Guide to the Feathers of Western European Birds, emergedfrom the initialplanning sessions we had with the director of Delachaux et Niestlé. The series of books on feather identification by Professor Hans-Heiner Bergmann was inspired by our flyer distributed at the International Ornithological Congress in 2006. A book titled Feathers: Displays of Brilliant Plumage by world–renowned photographer Robert Clark features several photographs of original feather sheets that were mounted for our Atlas of Feathers for Western Palearctic Birds, each depicted on a full double page. Even Audubon Magazine featured a series of photographs of original feather sheets from our Atlas of Feathers for Western Palearctic Birds. The Feather Atlas for North American Birds, published online by the Forensics Laboratory of the U.S. Fish and Wildlife Service, was inspired by our original project description in the Conference Proceedings of the International Bird Strike Committee. The Featherbase website, which gets several million visitors per year, adopted the same grey background colour that we had chosen for our illustrationsand also adopted the idea of depicting wing and tail diagrams in the way that we presented in our original project description.
The study of feathers has an obvious application for species identification, particularly when dealing with bird remains. But can a study of feathers also provide us with an insight into bird evolution and taxonomy, or indeed other areas of research?
Yes, indeed, much can be learned on these topics through the study of feathers. Subtle variations in the phenotype constitute the raw material for natural selection to act upon. Through the study of feathers, we can gain a deeper understanding of evolution. The high amount of phenotypic plasticity in bird wings is a clear example of evolution in progress. Many species exhibit subtle fluctuations in the extent and depth of emarginations on their primaries, resulting in different numbers of slots in their wings between different individuals. Another area of phenotypic plasticity is unusual variations in the number of flight-feathers. Our Feather Research Group compiled a large body of such variations from scientific literature and from our own research.
While feathers were not unique to birds, emarginationsare. Birds as we know them today are thought to have evolved from Mesozoic stem birds that coexisted with feathered dinosaurs. The only line that survived the cataclysmic event on Yucatan 66 million years ago evolved emarginations in their wings. If we consider birds as a class of their own, then the feature that distinguishes birds from feathered dinosaurs is the presence of emarginations. The evolution of emarginations can bring clarity into today’s scientific discussion on the origin of birds, which largely portrays birds as living dinosaurs, thereby blurring the line between reptiles and birds. Emarginations make birds unique. Neither bats nor insects nor pterosaurs have emarginations in their wings. Not all bird families living today have emarginations in their wings, giving rise to the question whether these bird families never evolved emarginations or whether their emarginations disappeared during the course of evolution. Emarginations can be lost either through the evolution of very narrow, pointed wings or through devolution into flightlessness.
Whether our findings have any relevance for taxonomy is up to taxonomists to decide. In the past, taxonomy was entirely based on phenotype, while today it is largely basedon genotype. Phenotypic variations do not play a significant role in current taxonomy, unless one is interested in the possible inheritance of epigenetic switches that regulate the expression of the genotype into the phenotype. For example, it is not clear whether the fine-tuning of the gradient in retinoic acid that is linked to two genes on the sixth and eighth chromosomes (and is responsible for the regulation of the vane width of feathers) was already inherent in the genome of Mesozoic stem birds and was activated through one of these epigenetic switches,giving rise to emarginations in modern birds. This question may be possible to answer by looking at the genome of bird families that appear to have never evolved emarginations so far, such as rails.
Who do you think these books will appeal to and who will benefit from such a comprehensive and high-quality atlas?
Anyone who visits the Featherbase websiteand finds the scans of feathers depicted there to be useful or interesting will also benefit from our work. If only 1% of the millions of visitors to this website see any value of having a printed Atlas with feather images of similar or even higher quality, this will make our Atlas of Feathers for Western Palearctic Birds worthwhile.
Many of the scans shown on the Featherbase website are from the collection of Dr. Wolf-Dieter Busching, the former director of the Naumann Museum in Köthen, Germany, who built up the largest scientific feather collection in the world, comprising feathers of around 2,500 bird species. During the time of the former communist regime in East Germany, it was difficult for Dr. Busching to obtain paper of a consistent colour for mounting the feathers in his collection. Therefore, his feather specimens are mounted on paper of many different colours, sometimes blue, sometimes red, sometimes yellow. Since the vanes of feathers are semi-transparent, the colour of the paper they are mounted on influences the colour of the feathers. In addition, the feathers in Dr. Busching’s collection often overlap each other, thereby hiding parts of the neighbouring feathers. In our Atlas of Feathers for Western Palearctic Birds, we show all feathers on the same standardised grey background and without overlap. In this way, each feather is fully visible and the colours of the feathers can be reliably compared.
Of course, the production of a series of books with high-quality colour plates is more expensive than running a website. The cost of such a series in printed form will limit the number of potential buyers compared to the number of visitors to the Featherbase website. We will keep the cost as low as possible to maximise the number of people able to afford our series in printed form.
The first volume in the series provides readers with a global overview of feather characteristics. Were there any particularly surprising data or revelations that resulted from compiling such a comprehensive collection?
There were several surprises indeed. Two of the most peculiar discoveries, or rather rediscoveries, were made in the families Tityridae (tityras, becards and allies) and in the family Trochilidae (hummingbirds). In the families Tityridae, two genera, Tityra and Pachyramphus, have a small, crippled primary number 9 in between normally-sized neighbours in the wings of adult males, while females and juveniles have normally formed wings. The function of the reduced-sized P9 may be related to sound production (sonation) during the display of adult males, but so far, we could not find any references in the scientific literature that would substantiate such an assumption. Amazingly, this peculiar phenomenon had even escaped the attention of Dr. Wolf-Dieter Busching, who devoted his entire life to the study of feathers, and none of our other collaborators in the Feather Research Group noted this phenomenon.
There are currently three mounted feather specimens of adult males of these two genera on the internet, one of them from the collection of Dr. Busching and two from other feather collections. In each of these three feather collections, the reduced-size P9 was mistakenly glued in front of P10 rather than in its correct position between P8 and P10, indicating that the respective feather researchers had no clue where this feather belongs and seem to have misjudged it to be a reduced outer primary, as is found in many passerines. However, when we consulted an older publication on feathers from 136 years ago, it turns out that this odd, reduced-size feather was already noted by Hans Gadow in 1888, at least in the genus Tityra, while its presence in the genus Pachyramphus seems to have escaped his attention, too.
The second peculiar discovery in the family of hummingbirds concerns the presence of emarginations at the tips of the outer primaries in males of 22 species from five genera. Most of us in the Feather Research Group had assumed by default that none of the hummingbird species have any emarginations, based on our experience with the many species for which we had examined feathers. The great majority of the 377 extant hummingbird species do not have any emarginations, as in the related family of swifts. So, it would have been easy to miss these exceptional few species if the effort had not been made to look at every single hummingbird species based on photographs of live birds. Again, the fact that only males of these exceptional species have emarginations, while females are missing them, leads to the assumption that these emarginations have something to do with the display flight of males. In this case, there is indeed a scientific paper dating back to 1983, which confirms this assumption for just one of the 22 hummingbird species in which males have emarginations. The only feather experts who knew about this study are Professor Lukas Jenni and Dr. Raffael Winkler from Switzerland. The authors of this study found that males create noises with their emarginated primaries and that these noises are used to protect nectar resources. Filling the slot between emarginated primaries with a glue film or clipping the distal 2–3 mm of these primaries caused males to sing more to protect their territories. We can deduce that the other hummingbird species in which males have emarginations use them in a similar way to produce sound. There is, however, a sixth genus of hummingbird in which males have inverse emarginations at the base of the primaries, not at their tips. This phenomenon of emarginations at the feather bases instead of at their tips does not make any aerodynamic sense, so it is likely that these inverse emarginations have some type of ornamental function in males.
These two discoveries, or rather rediscoveries, in the families Tityridae and Trochilidae teach us to remain open and not adhere to preconceived ideas. They also teach us to consult old literature that may have been forgotten or considered outdated.

The first volume will initially be published in black and white to make it affordable to as many people as possible. The online database of feathers is also available to everyone in the hopes that citizen scientists and members of the public will help to verify and correct the results. Given that birdwatching is such a popular pastime, do you think that there is a large body of untapped knowledge within the birding public?
There definitely is a large body of untapped knowledge within everyone, not only within the birding community. The key is to allow everyone to express their inner potential themselves. We are in favour of encouraging birders to publish their own data under their own names. Professor Peter Finke, who advises our Feather Research Group, calls this approach of empowering citizens to publish their own data Citizen Science Proper. What has been prevalent so far is Citizen Science Light, in which so-called experts scoop off the knowledge of the public and make a name for themselves with borrowed plumes, so to speak. Professor Finke published a book titled Citizen Science: The Underestimated Knowledge of Laymen (, which answers this question in much greater depth, giving many examples for birdwatchers in particular.
With regards to the global survey of emarginations in all bird species of the world, that became possible on the basis of photographs of live birds, which citizen scientists generously share on the internet. Our approach of opening our research findings on the number of emarginations in all bird species of the world by listing the internet links of the original photos that were used for this study is a way of thanking these many thousands of photographers. They all deserve to be mentioned as co-authors of our study. By sharing our findings and providing the original links to the photos that were used, we offer these photographers a way to give us their feedback on what we discovered thanks to their generosity. Anyone else who likes to share their observations on the photographs of live birds and scans of feathers that were used for our study is also welcome. We greatly value this interaction with birdwatchers and the general public.
How many volumes will the series eventually comprise, and do you know when they are due to be published?
After our last meeting in 2016, the World Feather Atlas Foundation purchased ten large scanners for our Feather Research Group. Five of these scanners went to the Featherbase team to support their endeavour of creating a World Feather Atlas. The remaining five were given to other collaborators in our group. The Featherbase team adopted the same grey background for newly mounted feather specimens as we adopted in 1998 for our Atlas of Feathers for Western Palearctic Birds. This unified the backgrounds on all scans, creating the basis for a potential cooperation to speed up the work on our Atlas of Feathers for Western Palearctic Birds.
The production of colour plates for the passerines took 24 years because they were all produced by only one person. If the work on the colour plates for the non-passerines is divided up by the holders of these ten scanners, it will be possible to produce the remaining colour plates more quickly. At the same time, the holders of these scanners can use them for their own projects.
Most important to us is to respect the copyrights of everyone who produces scans of feathers. Any contributions to our Atlas of Feathers for Western Palearctic Birds must be based on mutual respect for everyone’s free will. Those who contribute scans of feathers are treated at an equal level to those who contribute text. In the past, illustrators of bird guides were often underappreciated compared to the authors. All too often, illustrators were not even mentioned on the book cover. We feel that this relationship between illustrators and authors needs to be amended. Illustrators deserve to be cited alongside authors. In our Atlas of Feathers for Western Palearctic Birds, the work of those who produce scans of feathers is even more important than those who write the texts, because the texts can only be written on the basis of these scans.
The Full Edition of our Atlas of Feathers for Western Palearctic Birds will comprise a total of ten volumes including the introductory volume. Each of the subsequent nine volumes will cover about 150 bird species, adding up to a total of about 1,350 bird species. The Concise Edition will consist of two volumes. . The most precious thing we have to offer are the large-size colour plates in the full edition. The illustrations of feathers in the Concise Edition will be a cut-down version of the original colour plates and considerably smaller.
Atlas of Feathers for Western Palearctic Birds, Volume 1: Introduction is available to pre-order from our online bookstore.
In this review, I am revisiting the spectacular diversity of marine reptiles that flourished in the planet’s oceans and waterways during the time of the dinosaurs. After having gone without popular titles on the subject for almost two decades since Richard Ellis’s Sea Dragons in 2005, suddenly we have three. Last year (April–May) I reviewedThe Princeton Field Guide to Mesozoic Sea Reptiles and Ancient Sea Reptiles, and mentioned that this book was in the works. Ocean Life in the Time of Dinosaurs was originally published in French in 2021 as La Mer au Temps des Dinosaures by Belin/Humensis and has been translated into English by Mark Epstein. Technically speaking that makes it the first of this recent crop, though the English translation was only published in November 2023, after the aforementioned two works. It brings together four French palaeontologists and one natural history illustrator for a graphics-heavy introduction. So, what is in this book, and how does it compare to the other titles?
Ocean Life in the Time of Dinosaurs breaks down into two halves. The obligatory first short chapter introduces the state of the world during the Mesozoic Era 252–66 million years ago (mya), specifically the position of the continents (the palaeogeography) and the various extinction crises by which we divide this time span. After this, the first half is a very long chapter 2 that discusses all the major and minor groups: the “big three” (ichthyosaurs, plesiosaurs, and mosasaurs); the groups with survivors today such as the crocodylomorphs and sea turtles; and lesser-known groups such as hupehsuchians and thalattosaurs. The second half of the book consists of five chronological chapters that help you put all this diversity into some sort of logical order. This starts with life’s first coy attempts at reptiles-returning-to-the-sea in the Palaeozoic Era, the main event of the Mesozoic in three chapters (the Triassic, Jurassic, and Cretaceous), and the Cenozoic Era in which the survivors of the K–Pg extinction continued and sometimes thrived.
The book’s second half stood out to me for two reasons. First, it helps prevent the samerookie mistake that is often maderegarding dinosaurs: they did not all live at the same time. This may sound incredibly obvious and yet is easily andfrequently forgotten. Where marine reptiles are concerned, a good example of this is that the ichthyosaurs evolved ~252 mya and went extinct ~90 mya, while the mosasaurs evolved ~100 mya and went extinct 66 mya at the K–Pg boundary, the two groups thus overlapping for “only” 10 million years. Turtles and crocodylomorphs survived the K–Pg extinction and positively flourished, though some groupssubsequently went extinct and left no living descendants, such as the dryosaurids (a crocodylomorph lineage, extinct ~40 mya). The second reason I liked this chronological section is that it islargely told through the lens of key fossil localities around the globe (here, among others, Monte San Giorgio, Holzmaden, and the Oxford Clay).Though their names are often familiar and each of these deposits offers a unique view of a certain ecosystem at a certain time, they rarely get much attention themselves. The authors here provide just that little bit of extra information on their geography and stratigraphy, the history of their discovery and exploitation, and the palaeoenvironment that can be deduced from them.
Ocean Life in the Time of Dinosaurs is richly illustrated in full colour with photos, diagrams, and paleoart by Alain Bénéteau, including single and double-page spreads. There are several cladograms mapped onto timelines, with the simplified phylogeny of crocodylomorphs on page 69 particularly useful in visualising the uncertain placement ofthalattosuchians. Drawings show unique anatomical adaptations, explaining e.g. the evolution of turtle shells. The text is regularly interspersed with boxes discussing notable species or concepts such as proposed forms of swimming or adaptation of bones to life underwater. In short, the visual presentation of this book is outstanding.
I normally prefer to review each book on its ownmerits, butgiven that we now have two richly illustrated introductory books, there is no avoiding the mosasaur in the room. How does Ocean Life in the Time of Dinosaurs stack up against Darren Naish’s Ancient Sea Reptiles? As I alsoobserve about his Dinopedia, Naish is particularly interested in taxonomy and species diversity. Whereas the discussion of thedifferent groups here takes up 55 pages in chapter 2, Naish does this in 132 pages and six chapters. He goes into more detail on taxonomic conundrums and for most groups discusses more species. What the French quartet here adds are the five chronological chapters, extending their coverage of evolutionary events to before and after the Mesozoic. As mentioned, they also give more detail on key fossil siteswhereas Naish briefly mentions some of these in his chapter 1. My impression is that palaeontology buffs will want to get both books, despite the inevitable overlap. If, however, you are looking to buy just one book then Ocean Life in the Time of Dinosaurs is the most entry-level of the two, whileAncient Sea Reptiles providesmore detail (and in that scenario would be my book of choice). My original observationregarding Greg Paul’s The Princeton Field Guide to Mesozoic Sea Reptiles, that it is more of a reference work to be consulted after either of these books, still holds.
Ocean Life in the Time of Dinosaurs is available from our online bookstore.
Ever since wolves were reintroduced into Yellowstone National Park in 1995 they have been intently observed by biologists and wolf enthusiasts. Amongst these, biological technician and park ranger Rick McIntyre has to be the most dedicated, having watched these wolves from dawn to dusk every day for around two decades now. The Redemption of Wolf 302 is the third book in the Alpha Wolves of Yellowstone series and tells the story of an unlikely hero.
Though this book can be read by itself, you will get more enjoyment out of the unfolding multi-generational story arc if you read the previous two instalments. Furthermore, McIntyre refers to earlier wolves quite frequently and this book picks up right where The Reign of Wolf 21 ended, meaning the earliest part of wolf 302’s life is not told here. However, a brief introduction brings you up to speed.
One thing this book makes clear is that wolves have individual characters. Whereas wolves 8 and 21 were devoted males looking out for their pack, the current protagonist is anything but. With the death of 21 in 2004, the second-ranking male 253 temporarily takes over but is quickly ousted by two neighbours from the Leopold Pack: 302 and his younger nephew 480. 302, however, is not a natural leader. An increasingly baffled McIntyre spends the first half of the book describing many instances of his unusual behaviour: he runs away during confrontations with other packs, quickly becomes subordinate to his much younger nephew 480, sneakily tries to mate with females when 480 is distracted, occasionally steals food from pups, and is easily spooked by prey carcasses moving when his packmates tear pieces of meat off them. When 302 snoozes on a nearby hill while the Druids battle a rival pack, ignoring their howls, McIntyre seems truly exasperated: “I had been rooting for 302 to do better in life for over four years, but his total noninvolvement as 480 rushed to confront these wolves made me think 302 was a lost cause” (p. 118).

As a consequence, the first part actually revolves around male 480 who steps up as the new Druid alpha male. Through the years 2005 and 2006 McIntyre witnesses the waxing and waning of power between the packs. Several Druid wolves are killed by the neighbouring Slough Creek pack in 2005 and the Sloughs expand their territory aggressively. The tide turns from 2006 onwards, though, when an unknown pack moves in from the north and subjects the Slough’s breeding den to a brutal siege and later kills its adult males. Subsequent accidents and poor breeding seasons for the Sloughs allow the Druids to regain much of their territory by 2008.
It takes until 2007 for wolf 302 to redeem himself, by which time he is over 6.5 years old, well beyond the average lifespan of wolves in Yellowstone. He finally starts helping the Druid females and pups, and assists male 480 during hunts and fights with other packs. By 2008 he leaves the Druids with a group of yearlings in tow and, together with a female from the Agate Creek pack, forms the newly-named Blacktail pack. In one example of stories coming full circle in this book, 302 takes up residence in the territory of the now-extinct Leopold pack, the same territory he was born in. Without giving away further spoilers, several other storylines come full circle at the end of 302’s life. Although not tugging on the heartstrings quite as much as the story of wolves 21 and 42, I was nevertheless so invested emotionally in the fully-lived lives of these wolves that by the end of the book I struggled to hold back tears. 302 ultimately transitions from a rebel to an alpha wolf deserving of that status.
If you read the previous books then you know what to expect: no embellished writing but a detailed rendition of McIntyre’s field notes that recounts the day-to-day lives of these wolves. This book retains the same structure as The Reign of Wolf 21: short chapters bundled into parts, one part for each year. McIntyre has reverted to putting just one map with home ranges at the start of the book, together with diagrams of the changing pack compositions over the years. The Reign of Wolf 21 put maps and diagrams at the start of each part, which was a useful convention that helped keep track of all the players. It looks as if McIntyre decided that was not necessary for this book as it follows fewer packs.
Like previous volumes, this book overflows with interesting biological observations on e.g. play behaviour of pups and interactions with other species such as bears and ravens. A notable problem is the outbreak of mange, a mite-caused disease that leads to fur loss. Research using infrared cameras has shown the substantial loss of body heat this causes, and the resulting deterioration of health in the subzero temperatures of Yellowstone winters. McIntyre furthermore uses one chapter to shortly summarize observations on wolf injuries and mortalities that he mentioned in this and the previous two books. His observations mirror those of Wolves on the Hunt which showed wolves regularly suffer serious injuries while hunting prey, from broken ribs to fractured jaws. Sometimes these are fatal, though more wolves die as a result of fights with other wolves.

As before, McIntyre rarely inserts himself in the narrative. He mentions notable visitors to the park and personal achievements such as his nine-year streak of daily observations, even when temperatures drop to lows of -44°C. There are two other striking examples of McIntyre’s detachment in this book. One is an incident where he leaves an injured wolf after several hours of observation and finds him dead the next day. McIntyre sticks to an iron rule that he is here to observe, not to interfere, and that means all facets of life and death in the natural world. The second incident is the start of the wolf-hunting season in Montana when wolves are removed from the endangered species list in 2009. The wolves in Yellowstone National Park are still protected, but those venturing outside are at risk. Despite expressing his concern for their safety, he refrains from giving his personal opinion on the hunting of wolves.
This series was originally going to be a trilogy, but by the end, McIntyre foreshadows the subject of the fourth book: the alpha females, particularly female 06. Named after her year of birth, 2006, she was a granddaughter of male 21 and was legendary for her fierce independence. Though she has been the subject of Blakeslee’s book American Wolf, McIntyre is uniquely placed to give an account of her life. For now, wolf aficionados can delight in The Redemption of Wolf 302. With each book, the payoff of following their story in this level of intimate detail is getting bigger – these books are in a class of their own.
The Redemption of Wolf 302 is available from our bookstore.
Mushrooms have always been on the fringes of both the web of life and science in general, existing in the brackets between plant and animal in the minds of many. The Kingdom Fungi has, much like its constituents, rarely burst out into the light from the dark corners of popular science, that is, until recently. The last few years have seen Fungi of all forms thrust to the forefront of popular literature and medical research, which has generated a wave of renewed interest in the big questions around our mycelial cousins (after all they are eukaryotic cells just as we are). Where do they live, what can they do for us? And how can modern science get under the bonnet (pun intended) of these elusive but ultimately extremely important organisms?
If this surge in interest has managed to pass you by, or if you are already a budding (pun also intended) enthusiast, then this non-exhaustive, short-list of books will bring you up to date on the history and present knowledge of mushrooms and touch on the cultural importance of these diverse eukaryotes.
How Mushrooms Can Heal, Shift Consciousness & Save the Planet
No list of mushroom focussed literature would be complete without mentioning one of the most influential figures in modern mushroom science, Paul Stamets, in cohort with some of the eminent minds of modern mushroom science and opinion. This book, which accompanies the Netflix documentary of the same name, covers many of the same topics but presents them in an accessible way with full referencing should you wish to take the topic further and research in your own time. The book covers a full complement of topics, ranging from the concept of a wood wide web of interconnected trees and fungal partners, to how chemical science can harness the unique biological properties of a range of mushroom species to give us vital and useful medicines, remedial chemistries, and solutions to some of our most pressing issues in modern life including national security,combatting bioweaponry, and pollution solutions on a global scale. Each page is accompanied by rich and detailed macro–photography characterising some of the unique and beautiful forms of these organisms and will leave a distinct impression that there is a whole world out there still waiting to be explored. The book closes with a dive into the what ifs that surround looking at the world with a mycelial lens and posits some interesting theories on the very sources of human existence and our co-evolution with mushrooms itself.
Citizen Science, Fungi Fanatics, and the Untapped Potential of Mushrooms
Hailed as ‘a natural sequel’ to Merlin Sheldrake’s Entangled Life.In Search of Mycotopia occupies very much the same area in most people’s libraries. An in depth and developed look beneath the often-elusive veil of the field of mycology and all itsintricacies, this book takes a human–centric approach to the social side of the recent explosion in citizen mushroom science and how its these people that are driving development in this field before the lumbering pharma giants are able to gain a foothold. Focussing on the open-source nature of how modern mushroom research is conducted, it covers a range of topics that may be familiar to those already interested in this field butis alsohighly accessible to those who have not been introduced tothis dynamic and interesting world. There is morenuance to the way that questions are asked around the great potential and almost utopic ideas that are posited in other mushroom literature, but this does not make this book any less inspiring or interesting and is a great hopping on point for the first stop on the mycelium express.
How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures
Entangled Life is a colourful journey through one Merlin Sheldrake’s experiences with mushrooms and the niches which they occupy in everyday life.He adopts a ‘mushroom first’ perspective while investigating the reasons why mushrooms behave and perform in the way that they do, first leading with the ‘how’s,’ before following up with the ‘whys.’ Whether this is in a commercial, foraging, or clinical setting,seemingly the mycelium themselves posit the questions surrounding their unique biology and Merlin seeks to draw out answers and clarify what makes them so special to both us and the planet.He also leans on the cultural aspects of mycology and helps clarifyjust how important mushrooms have been in our history andarelikely to be in our future. This is an excellent book for those who want to build a strong foundation of knowledge for modern mushroom science but is also great for those who want to take a slightly deeper dive into the bigger questions surrounding mycology.The new illustrated edition is a pared-down version of the full-text version and instead replaces some of the larger passages of text with high quality macro photographs that are described in such rich detail in the original text.It is anexquisitegraphicaccompaniment to the original book.
Foraging for food is an easy way to connect people of all ages with nature. Some of us may forage unknowingly while picking juicy blackberries in the summer months, and some of us may be unaware of the vast array of edibles around us. Here we have selected a handful of items to forage through spring and summer, highlighting where you can find them and their culinary uses.
It is important to be certain of your identification, so if you are unsure, check all foraged foods with a professional because some plants have toxic look-alikes. Remember to forage responsibly by leaving plenty behind for wildlife and allowing plants to spore or set seed for regeneration.
Garlic Mustard, also known as Hedge Mustard or Jack-by-the-hedge, is a hairy herb in the mustard family. This plant has heart-shaped jagged leaves which emit a distinctive garlic odour when crushed, and has small, white flowers with cross-shaped petals. The species can grow up to 1m in height and can be found in woodland, hedgerows, cultivated land and on the borders of agricultural farmland. Each part of this plant is edible, but harvesting is best between March–April and July–September. Garlic mustard is best enjoyed before flower stalks develop, as this can create a bitter taste. The roots of this plant can be used as a substitute for pepper and horseradish and is said to taste like wasabi. The leaves have a garlicky flavour, and can be used as a replacement for traditional, store-bought garlic.
Wild Garlic (also called ramsons, bear garlic or broad-leaved garlic) is easily identified by its distinctive fragrance. When walking through areas of Wild Garlic, which are often found in large groups, you may catch a whiff of their characteristic garlic smell in the air. These areas are typically damp, shady woodland and can often be found with bluebells close by, as the pair have similar growing conditions. This plant can be seen from late winter till the end of spring, with flowers appearing in April/May. It has distinctive white, star-shaped flowers that grow in clusters. Their leaves are elongated, and when crushed release a pungent smell.
With a milder taste than shop-bought garlic, this plant is suitable for use in pastas, pesto’s and soups and can be infused into oils and vinegars. Only the flowers and leaves are edible, so it is best to leave the root to allow for regrowth – it is also worth noting that younger leaves are better for cooking, as older leaves can create bitter flavours. This plant can be confused with the poisonous Lily-of-the-valley, so it is best to smell the leaves before consuming them – alternatives will not have a distinctive garlic smell.
The Black Elder tree, a deciduous species, can grow to six metres in height and is identified by toothed, oval leaves. Each compound leaf has up to seven leaflets, arranged in opposite pairs with a single leaflet at the top. The flowers of this tree, elderflowers, bloom between May and June. Clusters of white, five-petalled flowers appear with prominent yellow stamens, and umbels of dark berries form in late August. Elderflowers can be found growing in a variety of conditions, and are largely non-selective with their environment, which can include hedgerows, woodland, scrubland, grassland and urban green spaces. Elderflowers have a long tradition of culinary use in the UK, using both berries and flowers for different purposes. Preserves, cordials, gins and puddings are all common uses of elderflower. The flowers can be eaten raw, but berries must be cooked before use. Elderflowers have a sweet and zesty taste and an aroma which is slightly lemony.
Although there are around 250 species of dandelion, here we refer to them collectively as they are difficult to distinguish from one another.
An instantly recognisable British wildflower, the dandelion features a bright yellow composite flower crown on a bed of large, jagged leaves. These species are very common and widespread, popping up almost everywhere from parks and gardens to roadsides and meadows. The roots, leaves, flowers and buds of the dandelion can be used for food and can be harvested from early spring to late autumn. The roots can be used as a coffee substitute and are famously used in the Dandelion-and-Burdock drink. Leaves can be added to salads and the dandelion flowers are often used in cakes. You can also make beer from the entire plant.
A hairy, perennial herb in the rose family, the Wild Strawberry can be found from May to August. The species is indiscriminate of their growing environment and can be found in a wide range of areas – it is found naturally growing in woodlands, hillsides, meadows, hedgerows and urban green spaces. Wild Strawberries can be identified by serrated, trifoliate (three leaflets) leaves and white, five-petalled flowers with a yellow centre. The berries of a Wild Strawberry appear similar to that of commercial strawberries but are generally smaller and rougher. These edible berries can be foraged from June onwards to make teas, cordials and puddings or can be infused into vinegars and sauces. With a sweet and juicy taste, these fruits can also be used as garnishes or used in salads.
A sure sign that summer has arrived, the Bramble is an iconic British summertime plant. This perennial shrub can be found up to 3m in height, featuring thorny stems which turn red with age and dark, jagged leaves. Come spring, a Bramble bush will have small groups of white or pale pink flowers with five petals. The fruit of this plant will appear up until autumn, with distinctive black, shiny berries. Ripening from green to purple-black, blackberries have a sweet, tart flavour. They are widespread in the UK and can be found in many habitats including woodland, hedges, fields and urban spaces. It is advised to pick blackberries away from busy roadways and paths to avoid pollutants and other contaminants. Picking from the upper half of the bush is also advised to avoid dog mess. The blackberry is a versatile fruit, with diverse culinary uses. It is commonly used to make jams, jellies and preserves but can also be used to make cordials and fruity teas.
Laetiporus sulphureus, named Chicken of the Woods, is a thick bracket fungus common in the UK. This fungus has bright yellow-orange clusters that fade to cream with age. The average cap can grow to around 45cm in width and is often found growing on the side of trees in broadleaf habitat between June and November. It is mainly found on oak trees, but can also be found on Yews, cherries, Sweet Chestnut and willow. It should be noted that if the fungus is found growing on Yews, or other poisonous trees, the fungus can cause sickness in humans. The firm texture of this fungus makes it a favorable alternative to chicken in vegetarian dishes, as the name suggests. It is often substituted in stews, stir fries, and marinated on skewers. When foraging, it is best to eat younger specimens to avoid a hard, leathery texture associated with older fungi.
Giant Puffballs are an astonishing sight when found in the wild. Their distinctive white, spherical silhouette can reach up to 90cm in diameter. This fungus has a soft, spongy texture inside, and a thick, velvety texture on the surface. A stemless variety, this plant is found directly on the ground and is often found in small clusters or ‘fairy rings’. As the fungus ages, it becomes browner in colour, compared to the firm, white flesh of young specimens. Giant Puffballs can be found in meadows, open pasture and woodland from July to September. They are widespread in the UK but are localised in habitat. This fungus is popular with vegetarian dishes – its firm, thick texture makes it a great substitute for chicken. It is often pan fried like steak, roasted or breaded and fried.
Marine noise pollution is inhibiting the recruitment and settlement of oyster larvae. A study from the University of Adelaide has reported a disturbance in oyster uptake in conservation projects where acoustic technology is used to attract larvae to new settlement areas. These invertebrates use natural acoustic cues to dictate their settlement, as well as navigation, communication and predator avoidance, making them more vulnerable to changes in their soundscape. Noise pollution from shipping, construction and machinery is interfering with these acoustic cues and limiting the benefits of acoustic technology in attracting oysters to reef habitats.
Artificial light in urban areas is impacting herbivory on trees. A study in Beijing showed that tree leaves in urban environments are visibly less damaged than rural tree communities. The study found that trees exposed to greater levels of illuminance from streetlights concentrate their energy on defense by thickening their leaves and producing chemical compounds such as tannins. The results suggested that trees exposed to high levels of artificial light may extend their photosynthesis duration, thus resulting in these characteristics. Ramped up defences means that thickened leaves are inedible for invertebrates, which could have cascading effects on the rest of the food chain, leading to a harmful reduction of herbivorous insects and predatory species in urban areas.

A badger vaccination programme in Cornwall shows promise in helping to manage bovine tuberculosis (bTB). The farmer-led pilot was conducted over four years in Cornwall and involved mass vaccination of badgers across 12 farms with huge success – around 74% of local badgers received the vaccine, with the number of infected badgers falling from 16% to zero. With bTB highly destructive to farmers and their livelihoods, the disease results in tens of thousands of cattle being culled each year and, although large-scale assessment is needed to measure vaccination impact on disease rates in cows, this programme could substantiate calls for the government to further support community-led vaccination.
Brazil is moving forward with plans to turn the Pantanal into an industrial waterway. The world’s largest wetland, comprised of over 1,200 rivers and streams, is home to an astonishing level of diversity and supports a host of vulnerable and endangered species, including Jaguars and Giant Otters. This biologically-rich environment is at risk from the Hidrovia Project – a plan proposing to build ports, straighten river bends and dredge the Paraguay riverbed to establish a shipping route for crops such as sugar and soya beans. This development could bring about irreversible damage to the environment – disconnecting the river from its floodplain, shrinking wetland habitats and causing disruption to seasonal flood patterns – meaning extinction for many of the animals taking refuge there.
The largest outbreak of avian influenza is infecting hundreds of species across the world. H5N1, a highly contagious, deadly strain of bird flu, is threatening the world’s biodiversity after infecting 485 bird species and 48 mammal species, including Polar Bears and captive tigers. The virus broke out in Europe in 2020, where it spread to a further six continents through bird migratory pathways. This evolutionarily flexible pathogen is ravaging wild animal populations across the globe, decimating 40% of Peruvian pelicans, 17,000 Argentinian Elephant Seal pups, over 30,000 Sea Lions and 75% of breeding Great Skuas in Scotland, among others. With continuous adaptation, the virus is now able to spread directly between mammals, raising greater concerns for human health and wellbeing.
The Wildlife Trust of South and West Wales (WTSWW) is set to begin the restoration of lost rainforests in Pembrokeshire. Historically, the west coast of Britain had large expanses of temperate rainforest that were gradually destroyed over hundreds of years. Only 1% of these habitats remain, and WTSWW wishes to return these areas to their former glory, improving habitats for wildlife in the area. Currently, the 146-acre land is designated for agriculture with nearly all fields grazed, but the Trust hopes to begin planting the first seeds in 2025, with visible growth in three years.
A continent-wide survey of Antarctica’s plant life has revealed growth in previously uncharted areas. This survey provides a baseline of lichens, mosses and algae, which will be used to monitor vegetation responses to climate change and inform conservation measures in the region. Researchers employed a European Space Agency satellite to sweep the area, and combined this data with field measurements. The survey has detected almost 45km2 of vegetation in the region, accounting for only 0.12% of Antarctica’s ice-free area, highlighting the importance of these environments.
Bats use echolocation, a series of high-pitched calls, to socialise, navigate their habitat and hunt for their prey. Most of these vocalisations are above the range of human hearing, so we require a bat detector to hear them. These devices allow us to monitor bat species by listening to their calls, observe their behaviours and feeding,and toidentify species in a given area. Here we look at a selection of our bat detectors, highlighting the key points to consider when expanding your kit.

In the latest work of the Poyser series, Rob Thomas brings us the definitive work on Europe’s storm-petrels. Meticulously researched by one of the world leading experts, this book follows European Storm-petrels, tracking their lives as they breed, migrate and overwinter. Rob shares the story of the group’sevolution, behaviour, ecology and adaptations, interspersed with charming personal anecdotes and observations.
Rob Thomas has been working at Cardiff University for over 20 years. He is a senior lecturer in Zoology who specialises in bird behaviour and ecology, and has been studying storm-petrels since he was 16. His work has taken him to Wales, Scotland, Portugal and the Faroes, where he studies storm-petrel breeding behaviour and long-distance migration journeys. He is the co-director of Eco-explore Community Interest Company and is a trustee of the Initiativefor Nature Conservation Cymru (INCC).
We recently had the opportunity to chat with Rob about what inspired him to write a book on storm-petrels, his favourite storm-petrel facts and more.
Can you tell us a little bit about yourself and what inspired you to write a book about Storm-petrels?
I’ve been birdwatching since I was a small boy – initially in the land-locked county of Breconshire in mid-Wales where I grew up, but as a teenager I started visiting the islands of west Wales and later Shetland, where I encountered storm-petrels for the first time. Since then, I have been fascinated by these remarkable little seabirds and the islands where they breed. Birdwatching led me into bird-ringing, and later into a career as a university researcher and lecturer, and storm-petrels have been the subject of much of my research and teaching work, including supervising various MSc and PhD projects on the behaviour, ecology and conservation of different storm-petrel species around the world. In recent years there has been an explosion of storm-petrel studies, partly due to advances in miniaturised tracking technology and the genetic methods that can be used to study storm-petrel diet and evolutionary relationships. Given the mass of new discoveries being made, together with renewed interest in the folklore, art and literature relating to storm-petrels, they became the natural subject for a new book about these truly remarkable seabirds.

What do you think is the biggest challenge facing these species, and how do you think we can work to minimise the impacts of this challenge in the future?
Seabirds are among the most threatened groups of birds globally, and storm-petrels themselves are vulnerable to a wide range of threats, including various forms of pollution (e.g. plastics, oil and other chemical pollutants, as well as light pollution), overfishing, and the looming impacts of rapid climate and oceanographic changes. For storm-petrels, perhaps the greatest threat of all comes from the arrival of non-native predators on their breeding islands; rats and cats have caused the local extinction of storm-petrels on numerous islands, as well as the likely global extinction of one species, the Guadalupe Storm-petrel. Fortunately, this threat can very effectively be addressed by the eradication of non-native predators, and this is steadily being carried out on seabird islands around the world, including in the UK and British Overseas Territories such as South Georgia. This is one of the most dramatically – and immediately – effective methods for helping storm-petrels that we have in the conservation toolbox.
There are often challenges with tagging storm-petrels due to their small stature. Are there any technological advances in surveying and research techniques that you would like to see employed and that would aid in tagging and monitoring them?
The miniaturisation of tracking technologies over recent years (geo-locators and GPS tags, as well as associated technologies such as accelerometers and depth-loggers) has led to a genuine revolution in our understanding of the behaviour and ecology of storm-petrels at sea. It is only in the last few years that GPS tags have become small enough to track birds as small as the smallest storm-petrels, including our own European Storm-petrel; the familiar species of the NE Atlantic (weighing approx. 25g), and we suddenly have a quite detailed understanding of where they go and what they do at sea. This tracking technology is now being deployed on some of the very rarest species (e.g. Monteiro’s storm-petrel of the Azores), to understand their conservation needs. One very exciting new development is the combination of tracking storm-petrels on their foraging trips at sea, with DNA analysis of the prey that storm-petrels deliver to their chicks, and remote-monitoring of behaviour in the nest burrow using miniaturised cameras and audio equipment – these can be used alongside more traditional methods, such as manual nest-checks and weighing of nestlings, to understand the factors on land and at sea that contribute to breeding success or failure.

I really enjoyed learning that the oldest European Storm-petrel recorded was estimated to be 40 years old, an astonishing age for such a small seabird. Do you have a favourite piece of information you discovered throughout researching and writing this book?
Yes! I have many favourite storm-petrel facts, including my provisional top five:1) storm-petrel chicks can hibernate (i.e. strategically reduce their body temperature and become torpid across multiple days) in order to save energy between food deliveries by their parents; 2) storm-petrels have the largest eggs relative to their body size (approx. 25-30% of the mother’s body mass) of any birds; 3) we still don’t know how many storm-petrel species there really are (the 28 formally-described species in the book is definitely an underestimate); 4) the New Zealand Storm-petrel was thought to be extinct for 176 years, until it was re-discovered in 2003 and happily seems to be thriving; and 5) the name ‘petrel’ may not refer to the disciple Peter walking on the waters of the Sea of Galilee as has often been stated, but may actually be derived from a much older old word ‘pet’, meaning ‘to break wind’ (yes, I am easily amused).
The world is currently facing a worrying decline in not only storm-petrel populations, but also many other seabird species worldwide. What would you say to people who might question the importance of safeguarding and conserving these animals
Most people have never heard of storm-petrels, let alone seen one. But this does not mean that storm-petrels are unimportant – they are perhaps more important that even I (a self-identifying storm-petrel fanatic) had assumed. Species do not need to be useful to humans to be an important part of the ecosystem that they inhabit; they are ecologically important in their own right, whether we are aware of them or not. Furthermore, storm-petrels reveal to us many of the ways in which our own activities as humans are impacting the natural world. Even storm-petrels, among the wildest of creatures, breeding in some of the most remote parts of our planet, are badly affected by our pollution, our entourage of non-native pets, livestock and plants, and they are highly sensitive biological indicators to the ongoing climatic and oceanographic impacts of our activities that are changing the composition of the planet’s atmosphere. For all of these reasons, it is important that we understand and act on the things that storm-petrels can tell us, or we ignore these messages at our peril.

Is there a species of storm-petrel that has so far eluded you, and which you would still love to see?
Oh yes, there are many! I have personally encountered only six or seven of the 28 or so storm-petrel species that are currently available (depending on how species are counted). I am hoping to spend the rest of my life occasionally meeting new storm-petrel species; two of my most-longed-for are the White-vented Storm-petrel (probably the smallest seabird in the world), and the Matsudaira’s Storm-petrel (one of the least-known and most-endangered of the storm-petrel species).
Finally, are you currently working on any other projects that you can tell us about?
Yes, an exciting new project involves working with local conservationists on the Faroe Islands (which host the largest colonies of European Storm-petrels) to understand the impacts (both positive and negative) of marine developments such as wind farms, fish farms and artificial lighting on these internationally important breeding colonies. Another very exciting new initiative is a collaborative project known as ‘Seaghosts’, led by Raül Ramos Garcia of the University of Barcelona in Spain, tracking the movements of different species of storm-petrels from breeding colonies across the North Atlantic, across their annual cycles. Seabirds ignore national boundaries, and such international collaborative projects are key to understanding threats and conservation solutions at a global scale.
Storm-petrels is published by Poyser Monographs and is available in harback and flexibound here.
