The NHBS Guide: Where to Hang and How to Maintain Your Nest Box

There is a shortage of natural nesting sites for birds and this has played a part in the decline of some of the UK’s most iconic species. It is easy to provide nesting opportunities for birds in our gardens and outdoor spaces, however, and with spring rapidly approaching, now is the ideal time to start thinking about nest boxes for your local birds. Locating your nest boxes correctly is one of the key determinants in how likely birds are to occupy them and with this in mind we have put together some answers to the most frequently asked questions about nest boxes – covering where and when to put up your boxes, cleaning and maintenance as well as dealing with predators.

You can browse the full range of nest boxes we sell online and, if you’re keen to find out more, check out the BTO Nestbox Guide, which is packed with essential information.

When is the best time to put up nest boxes?

There really is no ‘best’ time to put up nest boxes. By putting up boxes in the autumn you can provide much needed winter refuges for roosting birds and possibly increase the chance of them staying and nesting there when spring comes around. However, any box erected before the end of February stands a good chance of being occupied if it is sited correctly. Even after February there is still a chance that they will be used; tits have been known to move in during April and house martins as late as July. Therefore, put your nest box up as soon as it is available rather than leaving it in the shed!

Where should I hang my nest box?

When it comes to nest boxes, the ‘where’ is much more important than the ‘when’. Nest boxes must provide a safe, comfortable environment and protect the inhabitants from predators and the worst of the weather. This may be difficult to achieve; a safe location out of reach of predators may also be exposed to the weather, so have a good think before you start bashing nails in.

Nest boxes can be fixed to walls, trees or buildings and different styles of boxes are available which are suitable for each. Fixing to artificial surfaces means the growth of the tree does not have to be considered which is useful for Schwegler and Vivara Pro nest boxes which last for at least 20-25 years: a significant amount of time in the life of a small tree. If you’re planning any building work, remember that some bird and bat boxes can also be built directly into walls and roofs.

Locating boxes out of the reach of predators can be a challenge (weasels can climb almost anything), but there are things you can do to make it harder for them. Boxes in gardens should be located where cats cannot get to them and prickly or thorny bushes can also help to deter unwanted visitors. Some nest boxes also have anti-predator designs (e.g. Schwegler’s 1N deep nest box). It is best to avoid nest boxes that have a combined bird feeder and boxes should not be sited too close to the bird feeders in your garden. Visitors to the feeder may disturb the nesting birds and the feeder could attract unwanted attention from predators.

For many species the height of the box is not crucial. However, by placing it at least two metres off the ground you can help prevent predators and human interference. The direction of the entrance hole should be away from the prevailing wind and it is beneficial for there to be a clear flight path to the box. Crucially, the box should be also be sheltered from the prevailing wind, rain and strong sunlight, so in most UK gardens aim for an aspect of northerly, easterly or south-easterly. If possible, position the box with a slight downward angle to provide further protection from the rain. Some species do have specific requirements for where a box should be sited (e.g. house martins and swifts nests need to be sited under the eaves); please see our product details for particular instructions for different species. Wherever you position the box, try to ensure that you can still get access to it for maintenance. And finally, if possible, try to put it somewhere where you can see it, or invest in a nest box camera, so as to maximise your enjoyment of watching wild birds in your garden.

Is there anything else I can do to deter predators?

As already mentioned, location is the most important factor when trying to deter predators. Whilst some mammals can climb walls, a blank wall is fairly inaccessible so can be a good choice. Ensure that the box cannot be reached by a single jump from a nearby branch or the ground.

Box design can also help deter predators. An entrance hole reinforced with a metal plate will prevent grey squirrels and some avian predators from enlarging the hole and gaining access to the nest. Woodcrete and WoodStone boxes are too hard for any predator to break through. However, you can also reinforce a nest box yourself with metal protection plates or provide additional protection with prickly twigs. Deep boxes may prevent predators reaching in and grabbing nest occupants, although some tits have been known to fill up deep boxes with copious quantities of nesting material. If using open-fronted nest boxes, a balloon of chicken wire over the entrance can work well. If you live in an urban area, cats are likely to be the most common predator. Gardeners have long since used various methods to exclude these unwanted visitors, such as pellets, electronic scarers and even lion dung (available from your nearest obliging zoo), all with varying degrees of success.

How do I manage the nest box?

A well-designed nest box will only need one annual clean in the autumn. It is important not to clean out nest boxes before August as they may still be occupied. Wait until autumn and then remove the contents, scattering them on the ground some way from the box to help prevent parasites re-infesting the nest box. Wear gloves and use a small brush or scraper to remove debris from the corners. Boiling water can be used to kill any parasites remaining in the box, but remember to leave the lid off for a while for it to try out. Do not wait until the winter to clean out nest boxes as birds may already be roosting in them. The tit species do a thorough clean out of any old nesting material or roosting debris before they begin nesting again but it will save them energy if you can help out.

How many nest boxes do I need?

The exact amount of boxes required will depend on the species and the surrounding habitat. As a very general rule of thumb, start with ten assorted small boxes per hectare (ensure uniform spacing between boxes). Keep adding several more boxes each season until some remain unused and hopefully you’ll hit on the correct density of boxes. However, even if you only have space for one box it is still worthwhile, providing it is suitably located. Many UK bird species need all the additional nesting habitat they can get.

If you are interested in installing a nest box camera into one of your bird boxes, take a look at our “How to choose the right nest box camera” article, for more information on choosing the model that’s right for you.

Further information about individual nest boxes, including advice on positioning, can be found alongside each nest box in our range. If you have any other questions or would like any further advice, then please get in touch with our team of Wildlife Equipment Specialists.

Steller’s Sea Eagle: An interview with Richard Sale

Standing a metre tall, with a wingspan approaching three metres, the Steller’s Sea Eagle is a magnificent and impressive bird.

Published in November, Richard Sale’s new book is the first English-language study of this bird of prey. A translation of an earlier Russian book written by Masterov and Romanov, the English version benefits from significant updates and a wealth of new photographs.

We recently chatted with Richard about the Steller’s Sea Eagle, his passion for birds and his love of the Arctic.

In your author biography you are described as a physicist with a PhD in astrophysics. Is physics still a part of your life or do you now devote all of your time to your writing and natural history studies?

Physics will always be a part of my life. I started out as a working physicist, at first as a glaciologist in Switzerland because they paid me to stay in the mountains where I could climb on my days off. Then I moved back to the UK to work. After a few years I left full-time employment and started a consultancy which allowed me to share physics with my love of birds and of snow and ice.

You obviously have a huge passion for birds, and you also spend much of your time studying Arctic ecology. Where did these twin passions come from?

The love of birds started with my father who was a birdwatcher. Our holidays were geared around the breeding season and we went to the moors rather than the beach. He taught me to really watch birds, not just to be able to name them but to able to understand their habits. My other love as a kid was climbing; at first rock faces, then mountains. The love of snow and ice and birds led naturally to wanting to visit the Arctic. After the first trip I really didn’t want to go anywhere else, especially as I am no lover of hot weather.

How did the collaboration for Steller’s Sea Eagle come about? Were you approached to work on the English version of the book or is it something that you yourself instigated?

I had visited Kamchatka in summer and winter and been in the field with Yevgeni Lobkov, one the experts on Kamchatka’s Steller’s. I subsequently went to Hokkaido several times to see the eagles on the sea ice. Then I found the Russian book and corresponded with Michael Romanov. That led to the idea of translating it into English, so I obtained the English rights from the Russian publisher. At first the idea was just to translate the Russian book, but by questioning Michael and Vladimir about sections of text, and then suggesting that we include my work on flight characteristics, the two of them suggested I should be co-author as the book was now looking substantially different from the original.

Can you describe your first sighting of a Steller’s Sea Eagle? How did it make you feel?

I mentioned Yevgeni Lobkov above. He and I took a trip along the Zupanova River in a Zodiac and I remember the first time a Steller’s came over us. It was low down and seemed to blot out the light because of its size. No one who sees a Steller’s can avoid being impressed and I was immediately enraptured.

I was intrigued to read that you have worked with a captive Steller’s Sea Eagle here in the UK. Can you tell us more about this experience?

Once in the Arctic, on Bylot Island, I was watching a Gyrfalcon hunting Arctic Ground Squirrels and because of the terrain, a narrow valley, I could see the falcon was not stooping in a straight line. That led to investigating the physiology of falcon eyes, and to designing a small unit with gps, tri-axial accelerometers, magnetometers and gyros (and other bits) to fly on falconry birds to study how they fly. I managed to get the weight down to a few grams – though that hardly mattered when I found someone flying a captive Steller’s in England as it weighed 5kg. It was flying the units on that bird that is in the new book. Atlas, the eagle, was flown in demonstrations for the public and allowed me to investigate wing beat frequencies, speed etc. It was great fun as he was such a docile bird, a real gentle giant, and being allowed to get so close to him was marvellous.

It seems that two of the main pressures on the Steller’s Sea Eagle are fossil fuel exploration from humans and predation from brown bears. Are there currently any population estimates for the species, and are you hopeful for their future survival?

The situation is not good. The company drilling for oil and gas have been helpful in taking enormous care over onshore works near breeding sites and are to be commended for that. But the fact is that, as human activities of all sorts have expanded close to Steller’s habitats (most of which are well away from the oil/gas exploration sites), the population has gone into decline. We can overcome bear predation by fitting anti-bear devices to trees. We can erect artificial nest and roost sites. But despite all of this, at the moment the population numbers are slowly coming down, probably as a result of global warming, though we are not yet definite about that. Hopefully the population will stabilise but only time will tell if our efforts have been sufficient.

Within a given year, how much time do you spend travelling and how much writing? Do you enjoy each part of the process equally?

Age is catching up with me now and so I spend less time in the Arctic than I did (when I could be there for many weeks during the breeding season). But I still get into the field regularly – particularly at the moment with my units flying on falconry birds and with studies on Merlins in Iceland, Scotland and Hobbies in England and Wales. But I also spend a lot of time in the library reading about birds and, sadly, the damage we are causing them through industrialisation and climate change. As everyone knows, there is hardly any money to be made nowadays as a writer of books on natural history and related topics, but I also enjoy the process of writing and preparing books for publication.

Another of your books, The Arctic, is due for publication in December. What’s next for you? Do you have another project in the pipeline?

That book is an updated, but shortened, version of one I produced some years ago with new photographs by myself and a Norwegian photographer I bumped into one winter out on the sea ice of Svalbard. We have made several journeys together since and stay in close touch as we share a love of the Arctic. The next will likely be an updated and expanded version of the one I produced on the Merlin. Merlins are my favourite raptor. Falcons are, in general, warm-weather birds. The exceptions are the Gyrfalcons, which are the largest falcons, the Peregrine (which lives more or less everywhere) and is also large, and the tiny Merlin. I am as entranced by these little birds making a living in the harshest climates as I am by the huge Steller’s.

Richard Sale is a physicist with a PhD in astrophysics, who now devotes his time to studying Arctic ecology and the flight dynamics of raptors. With Eugene Potapov he co-authored The Gyrfalcon monograph which won the US Wildlife Society Book of the Year in 2006. His other books include The Snowy Owl, Wildlife of the Arctic and the New Naturalist title Falcons.

Climate Change and British Wildlife: an interview with Trevor Beebee

Climate Change and British Wildlife is the sixth installment of the popular British Wildlife Collection. In this timely text, Trevor Beebee takes advantage of our long history of wildlife monitoring to examine the effects that climate change has played so far on British species and their ecosystems. He also considers what the future may hold for them in a constantly warming environment.

Trevor Beebee is Emeritus Professor of Evolution, Behaviour and Environment at the University of Sussex, Trustee of the Herpetological Conservation and Amphibian Conservation Research Trusts and President of the British Herpetological Society. He is also author of the Amphibians and Reptiles Naturalists’ Handbook and co-author of the Amphibian Habitat Management Handbook.

Last week, Trevor visited NHBS to sign copies of Climate Change and British Wildlife (signed copies are exclusively available from NHBS). We also took the opportunity to chat him about the background behind the book, his thoughts on conservation and his hopes for the future of British wildlife. Read the full conversation below.

Where did the impetus and inspiration for this book come from? Is it a subject that you have been wanting to write about for some time?

It started in the garden some 40 years ago. For me, first arrivals of newts in the ponds were a welcome indicator that spring was on the way and I logged the dates year on year. It gradually dawned on me that the differences were not random but that arrivals were becoming increasingly early. Climate change seemed the obvious cause, and as evidence accumulated from so many diverse studies, it seemed like a good subject to write about.

The research required to cover so many taxonomic groups so comprehensively must have been immense. How long did you work on this book, including research, writing and editing?

The book took about a year to write. Electronic access to scientific journals made the research much easier and quicker than it would have been 20 years ago. Editing also took quite a while, greatly assisted by the perceptive advice of Katy Roper (my Bloomsbury editor).

The book covers plants, invertebrates, vertebrates, fungi, lichens and microbes as well as communities and individual ecosystems. Are there any of these that you feel are particularly at risk? Or conversely, are there any that you feel are more robust and are likely to better weather the effects of continued climate change?

It became evident as I researched that cold-adapted species including Arctic-alpine plants and fish such as the Vendace are in trouble, and that worrying trend is likely to generate declines or even extinctions in the coming decades. The ecology of the North Sea is also undergoing dramatic changes, some of which have precipitated seabird declines, especially of species such as Kittiwakes that rely heavily on sand eels. At the other extreme, mature woodland seems relatively resilient to climate change.

We have a rich history of wildlife monitoring and recording in the UK, much of which is undertaken by volunteers. Why do you think this is?

I believe that the media can take much of the credit for stimulating these activities. The end of the second world war was followed by the publication of a plethora of natural history books, from the I-Spy series (I still have a copy of ‘Ponds and Streams’), through the Observer series to the flagship New Naturalists. Then came television, with pioneers such as Peter Scott and David Attenborough in the 1950s. We’ve never looked back, with Springwatch today regularly attracting two million or more viewers. Brilliant!

Do you think that a thorough understanding of long-term monitoring and datasets can and should inform our decisions about where to focus conservation efforts?

Yes indeed, and fortunately such datasets are steadily increasing. The recent State of Nature reports have relied heavily on them, and they provide solid evidence that decision-makers can hardly ignore. One proviso though. For some species, especially rare ones, it is still difficult to obtain the necessary information. It would be a great mistake to ignore the plight of plants or animals clearly in difficulty simply because we don’t have robust monitoring data.

How did you feel after writing this book? Are you optimistic or despondent about the future for British wildlife?

Relieved! Sadly, though, not at all optimistic. There are some well-publicised success stories, such as the resurgence of several raptors, but more than fifty percent of Britain’s wildlife species are in continuous decline and there’s no sign of an end to that. Climate change is a problem for some, but it’s not the main one. Postwar agricultural intensification is the major villain, and it carries on regardless.

What single policy change would you like to see to alter the future of conservation in the UK?

A serious commitment to change farming practices into ones that sustain our rich wildlife heritage. Research shows that this is possible without dramatic impacts on food production, despite the claims of the agrochemical industry. With a human population the size of that in the UK it will never be possible to provide enough food without imports and it’s about time that was accepted by farmers and politicians alike.

Finally, what’s next for you? Do you have another book in the pipeline?

The book I would like to write is one on the impact of overpopulation on British wildlife. It’s a sensitive subject but one clearly recognised by naturalists of the calibre of David Attenborough, Jane Goodall and Chris Packham, among others. The most serious issues, including intensive farming practices, relate directly to the number of people dependent on them.

Climate Change and British Wildlife is published by British Wildlife Publishing and is available from NHBS.

Signed copies of the book are available, while stocks last.

The Ray Society: Publisher of the Month

The Ray Society is the NHBS Publisher of the Month for October. To celebrate this, we have applied some special offers to a selection of their titles. View all Ray Society publications here.

The Ray Society was founded in 1844 by George Johnston with the aim of publishing the types of specialised, yet important, natural history books that were often overlooked or refused by other publishers based on the small profit that they would make.

The society was named in honour of John Ray (1628 – 1705), an eminent British natural historian. Ray was born in Essex and educated at Cambridge University. He published numerous works on botany, zoology and natural theology and his theories and writings are widely recognised as laying the foundations for the later works of both Linnaeus and Darwin.

Early membership of the Ray Society included HRH Prince Albert, William Yarrell, Richard Owens and Charles Darwin. More recently, Geoff Boxshall, Maurice Burton, Roger Lincoln, David McClintock, Brian Morton, Elizabeth Platts (our first female president), William Stearn, Alwynne Wheeler and many others have been active members. A detailed account of the history of the Society by Elizabeth Platts can be read on the Ray Society’s webpage.

To date, the Ray Society has published 179 books with special, but not exclusive, reference to the flora and fauna of the British Isles. One of their most recent publications, Dudley Clayton’s Charles Parrish, was co-published with the Royal Botanic Gardens, Kew, and includes all of Parish’s stunning paintings of Burmese Orchids. Other notable books published by the Ray Society include Gilbert White’s The Natural history and Antiquities of Selbourne, John Ray’s Methodus Plantarum Nova and An Introduction to Copepod Diversity by Geoffrey Boxshall and Sheila Halsey.

We are delighted to announce that NHBS has recently taken over the distribution of Ray Society publications. The timing is particularly exciting with the upcoming publication of George Else and Mike Edwards’ authoritative and comprehensive Handbook of the Bees of the British Isles. A culmination of over forty years of study, the production of this book has been supported throughout by the Ray Society and much of the original artwork was commissioned and funded by them.

Conservation Volunteering at the Cornish Seal Sanctuary

NHBS’ core purpose is to support conservation. To this end, all NHBS staff members can apply for up to three days of paid time during each calendar year to spend on practical conservation projects of their choice. This month, customer services advisor Alice Mosley spent some time working at the Cornish Seal Sanctuary. Read all about her experiences below:

The Cornish Seal Sanctuary not only rescues and rehabilitates seal pups, but is also home to a variety of other marine animals who live there all year round.

“Earlier this month I had the pleasure of volunteering at the Cornish Seal Sanctuary in Gweek as part of NHBS’ conservation volunteering scheme. As well as seal rescue and rehabilitation, the sanctuary has a huge focus on education of marine pollution, sustainability and how everyone can contribute to cleaning up our oceans.

The sanctuary at Gweek opened in 1975; the founders, Ken and Mary Jones had already been rescuing injured and abandoned seal pups at St Agnes for 17 years and needed a bigger site. It is nestled on the bank of the Helford River, at the entrance to the Lizard Peninsula, a Cornwall Area of Outstanding Natural Beauty (AONB). Now owned by the charity The Sea Life Trust, the sanctuary focuses on the rescue and rehabilitation of seals from all over the UK. On average, 60-70 pups are rescued each winter but the last year saw over 80 successful rescues. It costs around £2000 to rehabilitate each seal pup, so you know exactly where your donations are going!

A number of seals are resident at the sanctuary all year round and require ongoing care.

The sanctuary has a fantastic rehabilitation success rate of around 98%, but some animal’s ongoing health problems or individual circumstances mean that they can never be re-released. This means that there are a number of resident seals that require care all year round. The sanctuary has also become a home for other animals and birds which have needed moving or re-homing for various reasons; it is home to nine Humboldt Penguins (conservation status: Vulnerable), four sea lions and two Asian short clawed otters (also classified as Vulnerable).

As a member of the animal care team for two weeks, most of the work I undertook was daily husbandry tasks for the animals, such as cleaning, food prep, feeding and enrichment. I was also introduced to the husbandry training that most of the resident animals undergo, which allows staff to look in the animals’ mouths, ask them to lift a flipper or tail for physical health checks, or voluntarily enter their transport cages. All training the resident animals undergo is beneficial to their overall health, while also keeping their mind active. This was particularly interesting to me as I will soon be studying both captive and wild animal behavior at University.

Alice performs a routine health check on one of the sanctuary’s residents.

While it was the wrong season for rescue and rehabilitation (pup season is September to March), I learned a great deal about working in the field of animal care while at the sanctuary. I was impressed by the dedication of all the staff, and the obvious happiness and wellbeing of the resident animals. If you are in the area, or need any more reasons to visit the stunning rugged coastlines of Cornwall, I’d highly recommend a visit to the Cornish Seal Sanctuary”.

The Cornish Seal Sanctuary is located in Gweek Village in Cornwall (TR12 6UG). It is open 7 days a week (except Christmas Day) from 10am – 5pm (last admissions 4pm).

Curlew Moon: An interview with Mary Colwell

Mary Colwell is an award-winning writer and producer who is well-known for her work with BBC Radio producing programmes on natural history and environmental issues; including their Natural Histories, Shared Planet and Saving Species series.

Her new book, Curlew Moon, documents her 500-mile journey from the west coast of Ireland to the east of England to raise awareness and funds for the Curlew, now one of the UK’s most threatened birds. Part travel diary and part natural history, the book is also a beautiful exploration of the way in which the Curlew appears in local myths, culture and language.

We were delighted to chat with Mary about the book and about her fight to save the UK Curlew population before it’s too late.

I guess I’ll start with the obvious question – why Curlews? What is it about them that captivates you and has made you dedicate so much time and energy to raising awareness for their conservation?

That’s perhaps the most difficult question. I honestly don’t know why Curlews in particular, other than I love the way they look, how they sound and where they live. Those calls over wetland and meadow or over mountain slopes are soul-grabbing. W S Graham described the Curlew’s call as a ‘love-weep’ a melancholic, yearning, beautiful sound. I grew up in the Staffordshire Moorlands and back then, in the 70s, they were common, so perhaps they infiltrated my brain! What I found on the walk is that many people feel the same. To know them is to love them. And over the last few years, as I became aware of what was happening not out on the savannah or in a rainforest, but right here under our noses, I decided to try to help. A contract with the BBC Natural History unit came to an end and the next day I started to plan the walk.

Where I live in North Wales, on the banks of the Menai Straights, the sight and sound of curlew are very common. Living somewhere like this, you could easily believe that they are both abundant and thriving here in the UK. Do you think that this, along with a lack of understanding of their complete natural history (e.g. the types of habitat they require to breed, food sources and predator pressures) contributes to masking the problems they face?

For sure that is the case. The UK and Ireland population of Curlew are boosted by winter visitors. From August to March as many as 150,000 Curlews rest up and feed ready for the breeding season. But come the warmer months most disappear back to N Germany, Scandinavia or Finland, leaving our own breeding birds thinly scattered. Also, as Curlew don’t breed until they are at least 2 years old, juveniles may well spend all year on the coast. The story of loss is in the fields and meadows. A Curlew’s life is complicated, and we are only just getting to grips with that. It needs whole landscapes to feed, roost, nest and over-winter. They bind the coast to the mountains and country to country. It’s hard to understand, but worth the effort. They really are fascinating.

Poetry features heavily in the book and I absolutely loved how you explore the myriad ways in which the curlew features in the myths, legends and cultures of the areas you passed through. (I am currently in the process of moving to Clynnog Fawr so I was particularly thrilled with the tale of St. Beuno!). Why did you choose to style the book in this way rather than writing a more prosaic natural history and travel diary?

I think being a producer on Radio 4’s Natural Histories for two series deepened my understanding of just how much the life around us has contributed to art, literature, poetry, science, folklore and spirituality. For all of our time as humans on earth we have looked at the natural world and forged connections. We still do that today. Part of the reason for the walk was to discover how curlews have inspired us. I had known about the lovely story of St Beuno and the Curlew for a long time – enchanted by it – so I knew there must be more out there. And there certainly is!

Particularly at a time where it seems that we are encouraged to value wildlife primarily for how it can benefit us, and ‘ecosystem services’ type approaches aim to put a monetary value on our wild spaces and creatures, do you think the arts have an important role in highlighting and championing those species that might otherwise fade away without notice?

Yes of course, anything that helps us to re-engage with nature is vital, be that through arts or science or economics. People are complicated – each of us has so many facets, rolled into one being. We are consumers, parents, children, lovers, friends. We are both rational and irrational, emotional and calculating, loving and full of division. Spiritual, religious, atheist, agnostic, often all at the same time. The arts understand this complexity and great art touches all those facets. The role of the arts in our lives is incalculable, so it isn’t surprising it doesn’t appear on a financial spreadsheet. I’m not sure I could write a straight natural history of any animal, bird or plant. I will always want to delve into its connection to our lives.

With any conservation work, it can sometimes feel as though you are swimming against the tide, with every move forward followed by two moves back. Especially with a species such as the Curlew, where there seem to be so many challenges to overcome, how do you maintain the hope required to keep fighting and how do you prevent yourself from succumbing to despair?

I touch on this a bit in the book – in the section where I walk though the middle of England with a friend who is an ex- Dominican friar, a gay activist and a writer, Mark Dowd. He helped put my feelings into context. This wasn’t a walk that will necessarily produce tangible proof of more Curlews on the ground within 5 years. Rather it is in the realm of hope – that something good will emerge at some point. It was a walk of trust, that if you put yourself on the line, people will respond. And so I didn’t walk with the aim that there would be a 20% increase in curlews in the UK and Ireland by 2020 (although that would be great), rather it was underpinned by a hope that people will be more aware of what needs to be done and will act on it. The series of workshops I organised with help from so many good people also gave me hope. We may fail, we may yet lose curlews from large areas, but, as David Attenborough once said, “As long as I can look into the eyes of my grandchildren and say I honestly did what I could, then that is all I can do.” I agree with that.

My final question is of a more practical nature, as I’m fascinated by people who take time out of their lives to undertake challenging journeys. Are you a seasoned long-distance walker or is this the first walk of this length you have undertaken? How did you prepare for it, both physically and mentally?

I used to do a lot of walking, but then children came along and life changed. So for 20 years I didn’t do much. But determination takes you a long way – and going to the gym. I just felt ready for the challenge and was so sure it was the right thing to do. But I did suffer from blisters! Still, a small price to pay and a good excuse to buy new boots for my most recent long distance walk – 230 miles through the Sierra Nevada in California along the John Muir Trail. That was tough, it made 500 miles along footpaths look like a stroll in the park.

Curlew Moon by Mary Colwell is published by William Collins and is available from NHBS. You can read more about Mary and her work at www.curlewmedia.com.

The Plant Messiah: An interview with Carlos Magdalena

Carlos Magdalena is a botanical horticulturist at Kew Gardens, famous for his pioneering work with waterlilies and his never-tiring efforts to save some of the world’s rarest species from extinction. In his book, The Plant Messiah, Carlos shares stories of his travels and his work at Kew and, in doing so, opens our eyes to the delicate wonder of plants and the perils that many of them are now facing.

We recently caught up with Carlos to chat about plant conservation, his views on extinction and lots more.

In your book you describe your trips to some incredible places – most of which have resulted in the collection of valuable herbarium specimens and seeds for growing or storage. Where does the impetus for these projects come from? Do you get to choose the species and/or projects that you work on or are these assigned to you?

They can happen for various reasons. Sometimes, they are assigned to me, like the projects in Peru and Bolivia: there is a need for a horticulturist capable of speaking Spanish, with experience in propagation of tropical plants and therefore, they contact me and from there we start the ball rolling. However, there is always the personal interest, though this works in an indirect way. Because I have been interested for years in tropical waterlilies, especially those from Australia, I had built up masses of knowledge, contacts and experience and therefore one day, someone needs someone with those skills and they want you to join in their projects. My endeavours in Mauritius started when seeds were set in a Ramosmania plant in a glasshouse in London. After this happened, there was a need to bring back this species to the island. Since this was a very genuine reason that could be solved at a very low cost, funding was allocated soon to travel and then, any time I go, I return with many more species that need working on to secure them ex-situ so you establish a working relationship with the country. There is so much work to be done that at the end of the day, money and time are the limits to be honest, but especially, funding is the main issue I have.

Many of the methods you use for germinating seeds and propagating plants have been considered unorthodox, and this is undoubtedly one of the reasons behind your outstanding achievements. Did you find that your peers and colleagues were initially suspicious of your techniques and approach, or did you always feel supported in your methods?

I guess they are not that unorthodox after all, I will say is more in the lines of ‘if something does not work, let’s try something else’, which is a bit unorthodox but also the sensible thing to do in those cases. I guess it is always tricky to swim against the ‘mantras’ or certain situations where is easier to stick to ‘oh, it won’t work because it cannot be done’ but even when I can be a victim of this myself, I try to do my best to think that you never know if you don’t try. Horticulture is a bit complicated since there are so many aspects to take into account. Science has a big part to play in it, but there is also that bit that is more like cooking, not witchery, but no white lab coat stuff either.
In cultivation, there are too many factors, compost types, light, humidity, temperature, temperature fluctuation, pests, seasons, fertilizers, nutrient levels, and so on and so forth. It is very difficult sometimes to come from an answer as result of traditional science when trying to work out what are the best parameters for each of the 400,000 known species of plants. Good basic science knowledge is vital, but the capacity of guessing, the ability to acknowledge and correct your own mistakes, to be capable of observing very small changes in the general looking of a plant (which I guess involves good photographic memory) are equally important, throwing in a bit of ‘gut feeling’ as it can help too! Sometimes first you manage to grow a plant by ‘play it by the ear’ and if you succeed and manage to grow many, then you can do the empirical work in a more traditional scientific manner, but first, it has to grow!

Many of the processes you describe in your book are very labour intensive and appear to involve a certain amount of trial and error. With the understanding that time is of the essence for many of the species you work with, and that availability of seeds may be severely limited, how do you cope with the prolonged uncertainty and pressure that must surely exist when attempting to germinate seeds or propagate cuttings?

You try to do the obvious first. Sometimes you know that something works very well with that family, so you will try that first. If it does not work you need to come up with a theory of ‘what happened’ and then create a scenario that tries to prevent that situation happening again. When quantities of seeds are abundant, then that makes things easier since you can try many things at once. With very small quantities of material this is not possible, so you try to use safer options. Seeds that cannot be dried die if you dry them. Seeds that need to be dried to germinate can stay wet for a period after harvesting, so if the seeds have not been dried already, I may sow them without drying in a way that I can recover it later to try a dry, then wet method. If something can be undone, sometimes takes preference over some action that cannot be undone. If that fails, then try plan B. if everything fails and there is no more material, you had that experience so that next time something is available you can try something else. However, were the seeds non-viable? Were they too old? It can be a bit tricky to get the whole picture sometimes. There are quite a few general rules that help, the difficulty is to spot the exceptions to the rule. In these cases, experience is the mother of science and not the other way around, but then, you have to be sure that whatever change you want to do make sense from a natural science point of view.

You frequently state in your book that extinction is unacceptable. How do you feel about the proposals by some ecologists that our modifications to the planet have in fact stimulated evolution, and that extinctions and non-native invasions are just part of a natural process, albeit it one that our actions may have accelerated?

First, I think that even if something is naturally going extinct, it should be preserved. No-one questions that we preserve items such as cathedrals or classic paintings under the excuse that ‘oh well, naturally they will fall apart and disintegrate in time’. They are an immeasurable resource and relevant part of our heritage. Regarding the invasive introductions…this is complex and cannot be summarized in a simple statement like the one above. There are species that naturalize and do not create a massive change, they just integrate as another item in the system, others occupy heavily pre-damaged ecosystems, so in fact, and they are a symptom rather than an illness of the damaged ecosystem. Look at Buddleia and its preference for cracks in concrete, brownfields, and decaying urban environments. Conservation is in a way altruistic (every species should have the right to live, just because it is a species), but also is an act of egoism and self-preservation because they are so useful to us in many ways. The more that we can keep, the more biodiverse the planet will be. As earlier stated, it is a very complex issue. What is the impact of invasive plants on CO2 absorption? Not sure what the answer to that is, but I bet that in some cases they are sequestering CO2, but not for all the species nor all the situations either. Avoiding extinctions should be always high on our agendas. We can aim to preserve many species long term, even if we still allow for lots of human changes taking place, but only if we can stop climate change and we manage the land properly. If we think ‘yeah, is all part of a natural process’ then we have to admit that burning fossil fuels is as natural as flying rabbits from Spain to the Antipodes, and also, that climate change will lead to a mass extinction but then, it will recover in a few million years later? No thanks, I rather keep the world as it is, beautiful and biodiverse, because guess what, nearly all of it is avoidable. Key word here: avoidable.

Animal conservationists often bemoan the fact that it is difficult to get the public interested in the “non-charismatic megafauna”. So, while the whales, tigers and pandas of the world have plenty of public attention and support, the plankton, toads and flies are often neglected. Do you feel this problem exists within the sphere of plant conservation too? Are the beautiful “charismatic” plants given attention over the less visually striking species? Or do you think that plants as a whole are neglected? As an extension of this, how do you think we should go about getting the public to care about the conservation of plants?

Firstly, yes, I think that plant conservation is low on people’s minds when compared with furry large animals. True that. But to be fair, a subspecies of the Javan rhino was declared extinct in Vietnam in 2011 and all the populations of this emblematic mammal are declining badly despite its cuteness, so there is work to be done with animals for sure.
I think we need to understand that plants are more important to our survival, and to the animal species survival than we think they do. With plants, we need to know them better before we can truly appreciate them. There is no Rhino without savannah and we need to look at the savannah more like a vegetation community rather than a background setting for Rhinos. Plants are the green glue that sticks the planet ecosystems together. We need to look at the system more, but systems are made of components and we cannot lose them if we want to keep the system going. It is always easier to attract funding and interest to showy plant species. Sad but true, but on the other hand, many stunning looking species are threatened and nothing much has been done. We need to raise the game in all departments of conservation. At the end of the day, it is the planet that we are protecting, not single species only. I have the feeling that avoiding plant extinction is easier than animal extinction, at least ex-situ. Yet, there are more instances of animals being reintroduced to the wild than plants. Sometimes, you need to introduce animals to recover the vegetation, i.e wolves rather than planting trees. Sometimes you may need to plant trees to reconnect two populations of large mammals. Fisheries rely heavily on seagrass and mangrove forest. Those two marine habitats fix massive amounts of CO2. Does global warming affects Panda’s favourite food? Rather than focus on animal vs plant conservation, we need to do this: to focus on single species so that they do not go extinct but also make sure that the worlds ecosystems are functioning. Easier said than done, but I refuse to accept that ‘cannot be done’. It is all avoidable.

Finally, is there a plant, either extant or presumed extinct, that you dream of seeing during your lifetime?

Only one? The trouble here is what to choose…there is so many things I do not want to miss in my life time. Never seen the redwood forest, I’ve never been to South Africa, Madagascar, New Guinea, Socotra…just to name a few incredible biodiverse areas that contain 100s of interesting ‘must see’ species. The discovery of a living fossil plant in the likes of Ginkgo or the Wollemy pine would always be very exciting…indeed the reappearance of an extinct species is always uplifting, however, if I have to choose, I go for the ‘extinction avoidance’. Mostly because, if I’m aware it is about to happen, and when it happens, it is so depressing. So I choose this: to produce and germinate seeds of Hyophorbe amaricaulis from Mauritius. Only one palm tree left, and decades of failures mean that is likely it will go extinct during my lifetime. I’m aware of this, and I cannot bear the thought of waking up one day to the news that a cyclone has split it in half.

The 100 best articles for ecologists

Keeping up to date with the latest research is a key part of any career in science. However, the push for researchers to publish early in their career and at frequent intervals means that there is now a seemingly unconquerable body of literature available to sift through. Because of the time-consuming nature of reading, processing and assimilating all of this information, the unfortunately result is that many researchers only find time to read the “hot” papers that are well publicised, or they focus primarily on papers that are recent and well-cited.

Image by brownpau via Flickr (CC BY 2.0) — The days of searching through library index cards are now a distant memory.

The advent of online journals also means that the days of physically searching for articles using paper records and traipsing around library stacks to locate a particular journal edition are a thing of the past. One result of this is that students and researchers who use the same or similar online search terms are likely to be directed to the same sub-set of papers, to the exclusion of other thematically similar but less relevant articles.

On the face of it, this may seem like a good thing, but it ignores the fact that methodological and conceptual insights are often to be found in papers which are not directly related to one’s own research; papers that would have been found more frequently when searching in a “bricks and mortar” library. It also means that older papers, which are still of importance for providing a good grounding in both methods and concepts, may be overlooked. By ignoring these older papers, the risk of repeating work that has already been undertaken or explored, is also higher.

With these concerns in mind, Franck Courchamp and Corey Bradshaw from the Université Paris-Saclay in France and Flinders University in Australia have taken it upon themselves to produce a list of the top 100 articles that every ecologist should read. Their key objective was to propose a list of seminal papers that, regardless of date of publication or specific subject area, would provide ecologists with a well-rounded understanding of ecology.

To create this list, they first assembled a long-list of 544 paper which were nominated by a group of 147 ecology journal editorial members; individuals that were recognised as experts in their field and who have an excellent knowledge of publications in their subject area. This list was then ranked via random-sample voting by 368 ecology experts and the top 100 papers collated into a comprehensive and varied reading list.

A century and a half after its publication, Darwin’s paper on natural selection remains a key ecology text.

Perhaps unsurprisingly, the number one paper on the list was Darwin and Wallace putting forth their theory of natural selection. Published in 1858, this entry also represents the oldest paper on the list. More surprising was the average age of the top-ranked papers, with a huge number of them being from the 1960s and 1970s whilst very few were included from the 21^st century. Most of the papers were not published in journals with a particularly high impact factor and, in many cases, they did not receive an unduly high number of citations, indicating that citation-based selections are not always the most appropriate when selecting papers for background reading.

The final list provides ecologists with an excellent starting point for establishing a well-rounded understanding of basic ecological theories. Whether you’re an early-career scientist, a well-established researcher or even a keen amateur with an enquiring mind, there is plenty here to expand your knowledge.

The list of 100 papers, together with a description of the methods and discussion of the subject, is published in Nature Ecology and Evolution and is available to view online.

Flight Lines: Interview with Mike Toms

The Flight Lines Project is a collaboration between the British Trust for Ornithology (BTO) and the Society of Wildlife Artists (SWLA). Using a unique combination of art, stories and science, this project aims to explore the lives of migrant birds and to highlight the challenges they face in a rapidly changing world.

In this interview with Flight Lines author, Mike Toms, we talk about the relationship between art and science, the importance of volunteer ornithologists and cultural differences in our attitudes to birds.

I’m curious about the perceived division between the arts and the sciences. While it’s true that many artists portray images of the natural world in their work, there are not many situations where artists and scientists are required to work together towards a common aim. Flight Lines is obviously a wonderful example of this – where did the idea for the project come from and what do you consider to be the most important thing that came out of it?

There is growing evidence that audiences exposed to science and conservation messages through the creative arts are more likely to show meaningful change in their understanding, which suggests that those of us working in research should seek now opportunities to communicate the impact of our work. Flight Lines was made possible by the generous legacy left by Penny Hollow and the kindness of her executors. Penny, a long-standing BTO member was a regular at the Society of Wildlife Artists (SWLA) exhibitions, a great supporter and a lay member of the SWLA. The bringing together of artists and scientists to raise the profile of our migrant birds was a fitting tribute to her interests and something that we had been looking do alongside our programme of research into migrant birds. Not only has the project enabled us to tell the stories of our summer visitors to new audiences but it has also helped to underline how art and science can work together to effect change.

Our knowledge of where our migrant birds disappear to each year has vastly increased with the development of ever smaller and more advanced tracking devices and locators. What do you think will be the next big technological advancement in the study of bird migration?

It is the arrival of smaller and smaller devices that has revolutionised our understanding of the movements of migrant birds. The level of information that can now be collected through the use of GPS-tags and satellite-tags means that we can identify the sites and habitats used by migrant birds throughout the year. In some cases, such as with those tags that communicate via the mobile phone or satellite network, the information collected can be presented to the public in near real time, greatly adding to wider engagement with the science that is being undertaken. For the smallest birds, the tags used have to be retrieved the following year in order to download the data. As miniaturisation continues, we will soon be able to track the movements of Swallows, House Martins, Whitethroats and other small migrants in near real time. That will be a significant advancement for our understanding.

In the UK I think it would be fair to say that we have an above average obsession with birds and their welfare. This is in stark contrast to many of the countries you discuss in the book, where birds are often viewed mainly as food or hunting trophies. What do you think is responsible for this difference in attitudes?

It is incredibly important to recognise the cultural differences that exist between countries in terms of how birds are viewed. Many of these are deeply rooted and extend back through generations, each shaped by local beliefs and opportunities, by living conditions and by trade. The hunting of migrant birds in North Africa, for example, is shaped by at least three different drivers: some are hunted for food by people living in very poor communities; others are hunted because of cultural beliefs, and many are hunted because there is a sizeable market for such commodities within the Middle East. It is important that we recognise how attitudes towards birds differ across the globe so that we can deliver approaches to conservation that are sensitive and appropriate.

The subject of supplementary feeding is currently a hot topic with the recent publication of an article in Science showing how great tits’ beaks have changed size due to the use of garden feeders. However, the messages we receive about feeding our garden birds are very mixed. Do you think the amount of supplementary feeding that occurs in the UK is a good thing overall?

The provision of supplementary food is one of the most common deliberate interactions between people and wild birds, supporting a wild bird care industry within the UK worth an estimated £210 million each year. Despite the huge amount of supplementary food provided in gardens we know surprisingly little about its impacts, which is one of the reasons why the BTO has been funding research into this topic over many years. Supplementary feeding may increase the overwinter survival of small birds, shape the communities of birds living alongside us and alter migration patterns and behaviour. It may also change the dynamics of competition between species or aid the spread of new and emerging diseases. Before we can say whether or not it is a good thing we need to improve our understanding of the associated costs and benefits, and look at these in relation to other human-bird interactions, such as climate and habitat change.

Citizen science schemes are an incredibly powerful force in terms of obtaining large quantities of data and you frequently mention in your book how much of our knowledge about bird populations comes from the tireless efforts of volunteers. Do you think that being involved with a citizen science project is also empowering to the individual and can help to break down some of the boundaries between “professional” scientists and amateurs, making science and research more accessible to them?

The terms ‘professional’ and ‘amateur’ are often used incorrectly, suggesting that staff are professionals while volunteers are amateurs, when what is really meant is that staff get paid and volunteers don’t . Many volunteers are experts in their field, sometimes the expert, and the right approach to citizen science should recognise this. We know from various research studies that volunteers participate in citizen science for a whole host of different reasons, some linked to internal values – such as feeling good about yourself – and some to external – such as sharing expertise, contributing towards charitable objectives. A well run citizen science project should make the science being carried out more accessible to participants, enabling them to see how their contribution is being used to answer a particular research question and empowering them to recognise the impact that their involvement is facilitating.

Do you feel that your art is influenced by your love of birds and wildlife and, conversely, do you feel that your art affects your appreciation of the natural world?

Some of my writing – the prose and poetry – is influenced by the natural world and by the sense of place. This feeling for the natural world is equally evident when I am participating in BTO surveys, especially the Nest Record Scheme, where significant time is spent immersed in nature, watching birds and their behaviour in order to find and monitor nesting attempts.

Manta: Interview with Guy Stevens

With their horn-shaped cephalic fins and large, gaping mouths, manta rays have long been the source of mariners’ myths and legends. Today, we know much more about these curious creatures, although many features of their lives and behaviours remain a mystery.

Marine biologist and co-founder of the Manta Trust Guy Stevens has spent many years researching mantas in an effort to understand their lives and to promote conservation practices that will ensure their continued survival. In Manta he has joined forces with National Geographic photographer Thomas Peschak to create a visually stunning and informative tribute to these animals.

To coincide with the re-release of the book, we recently spoke to Guy about his work with Mantas and the conservation challenges that they face.

Your life as a researcher and CEO of the Manta Trust must be incredibly varied and exciting. I’m curious what a typical day in the life of Guy Stevens looks like. Or, if a ‘typical’ day is unheard of for you, can you describe a recent day for us?

My days tend to be dictated by where I am. When in the field I am usually diving or freediving with manta rays on a daily basis, collecting data or guiding tourist expeditions. However, increasingly the majority of my time is spent on my computer behind a desk responding to emails, having Skype calls, writing papers, applying for grants and managing an ever increasing manta team.

Setting up an NGO must require an immense amount of work and passion. What did you find most challenging about the process and, as an extension of this, what advice would you offer other conservationists who are hoping to travel a similar path?

The most challenging part of the process, which still remains the main challenge today, is ensuring there are funds to enable the charity to carry out its mission. My advice to anyone wishing to follow a similar path would be to ensure you diversify your revenue streams.

The work conducted by yourself and other researchers around the world has contributed a huge amount to the body of knowledge about manta rays. What do you think are the next big questions that need to be addressed and how do you think new technologies (e.g. satellite and acoustic tagging / genetic techniques) will contribute to these?

From a conservation perspective one of the next big focus areas is to try and quantify the extent and impact of bycatch fisheries on the high seas (such as purse seine tuna fisheries) to manta rays and their close relatives, the devil rays; how many are being caught, which species, where, when and how many survive release after capture? Using post-release mortality tags can help us to estimate how many of the rays are likely to survive being captured after release, while the implementation of better management practices can hopefully reduce bycatch.

It is clear from your book that the problems facing mantas are incredibly complex and, as such, will require complex solutions. The final message I took from your book, however, appears to be one of hope. What significant changes would you like (or hope!) to see happen within the next five years in the arena of manta ray conservation.

I would like to see a world shifting away from industrial fisheries which employ unsustainable fishing practices; such as drift nets, long-lines, gill nets, etc. The oceans are rapidly being depleted and we need to protect much greater areas of this common resource from fishing if we want to stand any chance of safeguarding the world’s charismatic species like manta rays from extinction in the next few decades.

Finally – and I appreciate that you must have hundreds to choose from – is there a single encounter with a manta ray that really stands out in your memory and that will stay in your heart forever?

Yes, certainly the encounter which stands out the most is the one I describe in the book with the manta Slice, who I rescued from fishing line back in 2008 in Hanifaru Bay….there are lots of detail on this encounter in the book and here’s a link to the story on our website (although it is a bit outdated now); http://www.mantatrust.org/amazing-experiences-entangled-manta-rescue/
