Bowland Beth: An Interview with David Cobham

Bowland Beth dramatises the short life of an English hen harrier between 2011 and 2012 and immerses the reader in the day-to-day regimen of her life. Interweaved with her story is the larger tale of the species fight for survival under the constant threat of persecution. In this article our book specialist, Nigel Jones, talks to the author, David Cobham, about the plight of the hen harrier and his hopes for the future of this glorious bird.


David Cobham
The Author of Bowland Beth, David Cobham.

There are numerous organisations and NGOs in the book who want the same outcome for the hen harrier, but who seem to be in conflict as to how to achieve their aims. What strategy do you think would enable all these groups to speak with one voice; do you think this would help when confronting powerful lobby groups such as the landowners and their connections in government?

The problem lies in some organisations wanting an outright ban on driven grouse shooting. That is not going to happen as has already been demonstrated. What we all have to work for is a system of licensing driven grouse moor shooting. Controlled by DEFRA a driven grouse moor would be licensed to operate and granted the subsidies that are substantial.  If a case of illegal killing was proven in court the license for driven grouse shooting would be revoked for 3 years. I believe this would get a majority backing.

The hen harrier in your book is named Beth. I encounter some people who disapprove of naming animals, they claim this is anthropomorphism and inappropriate to conservation.  What would you say to those people?

Mark Avery in his review of my book saw exactly what I was trying to do. Ring numbers or tag numbers are impersonal. By giving them names it makes us feel closer to the birds. The news that Bowland Beth has died is much more heart wrenching than that 834759 has died.

Sadly, I have never seen a hen harrier. Your description of them is written with such a passion akin to awe that I am now determined to see one of these birds for myself. What chance does an everyday person like myself have of seeing a hen harrier in the wild?

A survey last year reported that there were 4 breeding pairs of hen harriers in England – none of them on grouse moors. The best time to see hen harriers is in the winter when there is a considerable influx of hen harriers from the Scandinavian countries. They pitch up from October on the east of England and can be seen as they come into roost in reed beds on the coast or in damp areas with shelter from silver birches inland. They return north to breed in mid-March.

The landowners say they need to make an income from the moors, and driven grouse shooting is the only way they can do this. They will put the case for local employment and, like the debate around foxhunting, accuse opponents of not understanding ‘the countryside.’ Do you think a ban on driven grouse shooting is the only way to force the landowners hand, or do you think working alongside landowners to assist with techniques such as brood management and diversionary feeding is the best way to proceed?

Brood management is just one of six measures in DEFRA’s save the hen harrier project. It is a concession to the grouse moor owners. This is how it will work. First, when a nest is found on a grouse moor, diversionary feeding must be tried. This involves feeding day old chicks during the six week period when hen harriers take grouse chicks. They are placed on a plank supported by trestles about 30 metres from the nest. Trials at Langholm showed that this method reduces chick predation by 86%. If another hen harrier nests within 10 km of the original nest then brood management comes into play. The clutch of eggs is removed and hatched in an incubator. They are taught to feed. When they can feed themselves they are placed in an aviary out on the moor. Monitored by experts they will be given a “soft” release and continue to be fed until they are self sustaining.

If the trial is shown to fail due to illegal killing it will cease immediately.

I’m quite cynical about this. I think a lot gamekeepers won’t allow a hen harrier to nest on their moor and furthermore there are not enough hen harriers breeding on grouse moors in England to justify this procedure.

There are some conservationists that advocate adopting a more laissez-faire approach to extinction, moving priorities to bio-abundance rather than biodiversity and accepting that extinction and invasive species are part of the evolutionary process. What are your thought regarding this way of thinking?

I quote directly from my book. An extract from The Diversity of Life by Professor Edward O. Wilson: “We should not knowingly allow any species or race to go extinct. There can be no purpose more enspiriting than to begin the ages of restoration, reweaving the wondrous diversity of life that still surrounds us”. The hen harrier was extinct as a breeding bird in England in 2013. Its fate lies in our hands now.

Despite the hen harrier being a totem and emblematic of a battle between conservationists and those wishing to preserve a ‘rural way of life;’ a quick straw-poll I conducted indicated little knowledge of the bird. However, with more knowledge, I believe the majority would care about the hen harrier. How can the plight of the hen harrier compete in a media blizzard of often superficial and meaningless content?

When Bowland Beth was shot we believe she had just found a mate. Her femur was fractured, six of her tail feathers cut through and her femoral artery nicked. She picked herself up and flew unsteadily off, streaming blood behind her. Her vision blurred and she crashed into heather. Don’t tell me that birds don’t feel pain. She must have been in exquisite pain. I know about pain. I broke my femur last October, and lay there for six hours before I was found. That is the bond I have with Bowland Beth.

Do you believe satellite tagging is a good way to monitor hen harriers, and if so why?

Illegal killing of hen harriers continues. There is an arms race – sophisticated satellite tagging versus state of the art weaponry. Since 2007 36 hen harriers satellite tagged by Natural England have “disappeared”. Bowland Beth was one of them. The Hawk and Owl Trust satellite tagged two hen harriers last year. The male, Rowan, was shot last October in the north of England. His leg was smashed and he was able to fly some distance before collapsing in the heather. Sorrel, a female, is alive and well and flourishing in Scotland.

Protecting the hen harrier requires dedication, passion and commitment to the cause of conservation, often from volunteers working long hours in all weathers. What would you say to inspire a future generation of conservationist to take up the baton?

To watch a young hen harrier successfully fledge from her nest and set out into the unknown is the start of a Great Adventure. Sharing this knowledge with other weary volunteers who have probably not seen anything all day re-invigorates them, gives them the impetus to go out again and search for that elusive V-shaped image of a hen harrier, searching up and down, for its favourite prey, short-tailed field voles.

Orison for a Curlew: Interview with Horatio Clare

Orison for a Curlew takes us on a pilgrimage in search of the slender-billed curlew; once a common sight in its breeding grounds of Siberia, but now diminished to a handful of unconfirmed sightings. In this article, one of our book team Nigel Jones, talks to the author, Horatio Clare, about conservation, environmentalism and his hopes for the future of the titular bird.


The author, Horatio Clare

Despite the rather gloomy prognosis for the fate of the slender-billed curlew, your book seems to me about hope. Are you optimistic that conservation will gain ground due to stories such as the plight of Numenius tenuirostris, or do you think this story is more of a prelude of things to come?

It is about hope. I do think the hunger for watching nature footage, and writing and reading about the natural world will translate, given the unavoidable nature of climate and environmental awareness as the world changes, into action. My sense of my generation, currently in our forties, is that we came out of an easy time – the nineties – well aware of how lucky we were, and how things were going with the planet and capitalism generally – and that we have not seen the best of us yet. We have been getting it together, I know of great people in powerful positions, and others doing tremendous work, and I hope things will change for the better. Brexit and Trump are shattering reversals for the world and nature, but not insurmountable. Moreover, it seems the slender-billed curlew may not be on the way out! A population may breed in Kazakhstan and the birds may have been seen and filmed a few years ago in Holland.

Being such a delicate and ethereal creature; do you think the slender-billed curlew was always vulnerable to possible extinction, regardless of human activity; was there a more dominant species pushing it out of it’s niche?

No I am sure we are the dominant species which pushed it out, by draining marshes and polluting the water. It was surely vulnerable in that it is highly specialised.

The relentless corrosion of diminishing natural spaces is a strong theme in your book. The argument for development is usually ‘people come first’ and, by definition, wild spaces are mainly unoccupied by people. I would love to see the hundreds of white pelicans, spiralling up to find the thermals that you describe. However, most of us will only see a spectacle such as this on television, or envisage it vicariously. For me this is the paradox of conserving wild spaces for their own sake – how do we get everyone involved with conservation when only a few people ever get to experience what it creates? How do we make wild spaces matter to everybody?

Knowledge of the natural world and knowing what you are looking at can make a walk in the garden, park or road a safari. That is the way you make every space matter: put names and stories on the creatures that inhabit it. Funnily enough I have written two children’s books on the subject! Which makes me think, children’s literature being a kind of menagerie, we all begin as nature-lovers; it’s just that some adults discount the planet’s marvels, and certainly its needs. And of course corporations exist solely to harvest the planet’s riches as quickly as possible, heedless of environmental cost, if they are allowed to be, for the benefit of share-holders. I think some form of cooperativism between individuals and between nations offers the only hope for long-term sustainability.

There are some conservationists that advocate adopting a more laissez-faire approach to extinction, moving priorities to bio-abundance rather than biodiversity and accepting that extinction and invasive species are part of the evolutionary process. What are your thought regarding this way of thinking?

It is a sin to cause the extinction of a species, as Prof Kiss puts it in Orison. To fail to prevent the extinction of a species seems of a different order, if hard to enjoy. If you regard our privilege of dominance as responsibility, then we have a duty to look after all of what used to be called God’s creatures. We should not really accept anything less than bio-abundance and biodiversity, should we?

I really enjoyed meeting all the people in your book; their dedication, passion and commitment to the cause of conservation was wonderfully described, without ever reducing them to parodies or caricatures. For me they represented the ‘hope’ in your book. However, they all seemed at odds with the world, probably viewed by their relative governments as part of an ‘awkward squad’ and their work and funding was often in decline. What would you say to inspire a future generation of conservationist to take up the baton?

With journalism going through tough times, there is no better way to have the fun and the interest of being the awkward squad, travelling the world, getting up the noses of baddies and making the planet a better place than becoming an environmentalist! What a blessed and admirable profession! What adventure it offers! And…the happiest people you meet are naturalists and environmentalists, on the whole, though they deal in tragedy and folly often.

Numenius tenuirostris Vieilliot, 1817

The hunting for sport, the mist nets and the bird markets make for a very threatening environment for migrating birds. However, it’s the drainage of the marshes for agriculture and the encroachment and contamination of heavy industry that you more frequently allude to as the biggest threat. Do you see hunting as a potential partner to conservation, or are those two pursuits always going to be in conflict?

Having just read Bowland Beth: The Life of an English Hen Harrier by David Cobham I feel hunting is unhelpful, if not abominable, but that may be a grouse-centric view. In Greece the numerous hunters are thought of with something like revulsion by some conservationists; the hunting I saw while living in Italy was an absolute disgrace. No doubt many hunters are great and ardent conservationists. Unfortunately many are not.

The slender-billed curlew sightings in recent history are difficult to verify. What are your hunches about their authenticity and when was the last recorded sighting that you believe was accurate?

The birds filmed in Holland in 2013 seem genuine but I am no expert. I believe they are seen – and recorded – now and then. I heard a report from Oman, but a confirmed sighting is a tricky thing: it seems you need two or more photos and absolute proof. My friend Istavan Moldovan is cautious about the 2013 footage – as I write he is chasing relict populations of Apollo butterflies in the Carpathians in Romania. Does that not sound like a great career?

The last question is a simple one, but maybe the most difficult to answer. I know you certainly hope so, but do you believe Numenius tenuirostris will ever be seen again?

I absolutely do. I am quite sure they are out there and it is my dream to see one! Thank you so much for your wonderfully intelligent and acute questions, quite the best!


Orison for a Curlew, written by Horatio Clare and illustrated by Beatrice Forshall, is published by Little Toller Books and is available in paperback and hardback.

Little Toller was established in 2008 with a singular purpose: to revive forgotten and classic books about nature and rural life in the British Isles.

Their Nature Classics Library series was established to re-publish gems of natural history writing, with up-to-date introductions by contemporary writers. The success of the series has now developed into a publishing programme which includes a series of monographs by authors like Fiona Sampson, John Burnside, Iain Sinclair and Adam Thorpe as well as stand-alone books – all attuned to nature and landscape and aimed at the general reader.

Each Little Toller writer brings something new to the series – but it’s always characterised by a deep understanding of the subject, combined with wonderful writing.  A sense of the personal reaction to the natural world is imperative. Little Toller also pay a great deal of attention to the aesthetic of their books, using artists to complement the writing to create a beautiful object, befitting Little Toller’s high publishing standards.

Little Toller is now preparing its books for the latter part of the year, notably the first ever biography of the legendary but enigmatic J A Baker, author of The Peregrine, and access to the new Baker archive has led to important new insights into his life. 2018 will see new books from Tim Dee on Landfill, a book about Ted Hughes and fishing called The Catch, and an examination of the landscape of the north of the Irish republic from Sean Lysaght. Little Toller’s sister charity Common Ground is also working on a large exhibition at the Yorkshire Sculpture Park next year, for which there will be a raft of publishing.

 

The Importance of Nest Sites for Birds and Bees

Changes in land use can result in strong competition between species that have historically survived alongside eachother, such as goldfinches and chaffinches. Goldfinch by Tony Smith is licenced under CC BY 2.0.

Over the last century, land use in the UK has changed drastically. Small mixed-crop farms, traditionally separated by lanes, hedgerows and wild meadows have been replaced with larger, more specialised facilities. At the same time, the density of grazing animals such as sheep and cattle has also risen substantially. This combination of land-use change and agricultural intensification has contributed significantly to habitat degradation and biodiversity loss, and has led to huge, often dire, changes for the wildlife that call these places home.

Understanding these processes is of huge importance to conservationists, and a considerable amount of research has been conducted into the broad scale effects of land use changes on biodiversity. It is less well understood, however, why seemingly similar species can be affected to a different extent by local changes in their habitat.

A recent study, conducted by Dr Andrew Higginson at the University of Exeter, suggests that competition for nesting space may be a key factor in the differences observed. His study used a mathematical model to predict the likely outcome when populations of birds and bees are faced with a reduction in suitable nesting sites. Results indicated that larger, earlier-nesting species tend to fare better in these conditions, but at the expense of smaller, later-nesting species who, in the real world, would either fail to find a nesting site or be forced into using a poor quality or risky location.

Dr Higginson’s results illustrate that, whilst two or more similar species can co-exist together very happily when there are sufficient nesting spaces available, as soon as these become limited, competition and conflict become inevitable. In severe situations, species that have historically thrived in the same environment may suddenly find themselves battling for survival.

A key message from the study was that conservation efforts should ensure that priority is given to the creation and maintenance of suitable nesting sites. Conservation practices often focus on provision of food for wildlife, such as planting wildflowers for bees and providing food for our garden birds. Preserving and creating safe and accessible places for these animals to nest, however, is just as critical if we are to ensure their continued survival.

How to choose a nest box camera

Nest box cameras provide an excellent way to observe the exciting nest building, egg laying and chick rearing behaviours of your local birds.

Deciding which nest box camera to choose can be confusing and several questions should be considered before you make your choice: Do you need a wired version or would a wireless option be best for you? Do you want a camera that you can fit into an existing box, or would you prefer to buy everything already assembled? Will you be able to view your footage on your PC or laptop? Do you want to stream your footage to a website? In this article we will address all of these FAQs and offer some simple advice to make sure that you get the best out of your camera.

Do you want a wired or wireless system?

Wired systems have a cable running from the nest box back to your house or classroom. This cable carries both the power to the camera and the signal from the camera to your TV. A wired setup offers excellent image quality but may not be ideal if you have children or pets in your garden or if a cable running to your bird box will interfere with the gardening. You will also need to feed the cable into your house, either by drilling a hole in the wall or by feeding it through an open window.

Wireless systems do not require a cable between the bird box and the television but instead transmit images to a small receiver situated inside the house. For some cameras, such as the Wireless Nest Box Camera Kit, a power supply will still be required for the camera (i.e. from a shed or outbuilding). Other cameras, such as the battery powered Wireless Nest Box Camera Kit have solved this problem by adding a battery box, allowing the camera to run off D-cell batteries. An advanced version of this camera system is also available. This includes a solar panel which will power your camera while the sun is shining, only switching to battery power at night or on dull days.

Another thing to consider with a wireless system is that the signal can be compromised by other wireless devices in the area or by trees and other structures between the nest box and the house. In some situations this can severely affect your image quality.

Do you want a complete kit or just the camera?

If you are new to this particular aspect of watching and listening to birds, a complete kit, such as the Nest Box Camera Starter Kit or the Wired Camera Bird Box, provide an excellent and economical choice. These kits include a bird box which has a camera ready mounted in the roof. An attached cable plugs into your television and supplies the camera with power. Alternatively, if you want a wireless option, the Wireless Camera Nest Box is a great choice and doesn’t require any complicated assembly processes.

For the handyman or woman who wants to put a system together themselves, either in a bespoke or existing nest box, the Nest Box Camera with Night Vision is a good choice. The camera comes with a 30 ­metre cable and extension cables are available to purchase separately. The Wireless Nest Box Camera Kit or the battery powered Wireless Nest Box Camera Kit are good options if you want to fit a wireless camera into your own bird box.

If you decide to go for one of these options then you will need to attach the camera to the ceiling or inside wall of your box yourself using small screws. A small file can be used to file down a part of the side wall to make a space for the cable to pass through. Alternatively you might consider buying a Camera Ready Nest Box which has a clip inside for attaching a camera, as well as a perspex window in the side which helps to improve the quality of daytime images.

What about watching on your computer?

All of the cameras and kits that we sell come with either a cable or wireless receiver that will connect directly to your television. If you want to view or save your footage onto your computer then an additional USB capture device is required. These allow you to connect your camera/receiver to the USB port of your computer and come with viewing software which allows you to watch and record your footage. Available for both Windows and Mac operating systems.

Can I stream my footage to a website?

There are lots of online services which allow you to stream a live feed from your camera online. Many are free if you are happy having adverts on your stream, or you can purchase a monthly or yearly ad-free plan. Our current favourite is Ustream (www.ustream.tv). Take a look at their website for lots of great resources to help get you started.

 

 

The Sensory Ecology of Birds: Interview with Graham Martin

The Sensory Ecology of Birds is a fascinating new work that explores the sensory world of birds from an evolutionary and ecological perspective. The author Professor Graham Martin gives us some insights into his inspiration, the incredible diversity of avian sensory adaptations, and how studying sensory ecology can help in developing practical conservation solutions.

 

Professor Graham Martin – Author of The Sensory Ecology of Birds

How did you first become interested in bird senses?

Through owls. As a child I used to listen to tawny owls calling all through the night in a nearby wood and I wanted to know what they were doing and how they did it. My father took me round the woods at night and that experience led me to wanting to know more about the eyesight of owls.

What inspired you to write the book and what kind of readers do you think would find it useful?

I have been studying bird senses all of my working career. Nearly 50 years ago I started to get paid for looking into bird senses; it has been a strange and exciting way to spend my time. After such a long time of investigating the senses of so many different birds I wanted to bring it all together, to provide an overview that will help people understand birds from a new perspective. I think anyone interested in birds will enjoy the book and find it useful. No matter which group of species intrigues you most, this book will enable you to see them from a new perspective. Understanding bird senses really does challenge what we think birds are and how they go about their lives.

Sensory ecology is a relatively new field of research; could you explain a little about what it is and what makes it particularly relevant today?

Sensory Ecology is basically the study of the information that birds have at their disposal to guide their behaviour, to guide the key tasks that they perform every day to survive in different types of habitats.  Different habitats present different challenges and to carry out tasks animals need different sorts of information. Birds have at their disposal a wide range of different sensory information, they are not just reliant upon vision. However, each species tends to be specialised for the gaining of certain types of information. Just as each species differs in its general ecology, each species also has a unique suite of information available to them. Sensory ecology is also a comparative science. It compares the information that different species use and tries to determine general principles that apply to the conduct of particular behaviours in different places. For example how different birds cope with activity at night or underwater.

Sensory Ecology also looks at why evolution has favoured particular solutions to particular problems.  I think the major result of this kind of approach is that it certainly challenges our assumptions about what birds are and also what humans are. We do not readily realise that our view of the world is very much shaped by the information that our senses provide. We are rather peculiar and specialised in the information that we use to guide our everyday behaviours. My hope is that people will come to understand the world through birds’ senses, to get a real “bird’s eye view”. In doing so we can understand why birds fall victim to collisions with obvious structures such as powerlines, wind turbines, motor vehicles, glass panes, fences, etc. We can then work out what to do to mitigate these problems that humans have thrown in birds’ way.

An understanding of how a species perceives its environment can be very useful in designing practical conservation measures. Could you give us some examples?

Yes, I have been involved in trying to understand why flying birds apparently fail to detect wind turbines and power lines, or diving birds fail to detect gill nets.  These investigations have led to a number of ideas about what is actually happening when birds interact with these structures and what we can do to increase the chances that birds will detect and avoid them.

How do you think that studying avian sensory ecology can enhance our understanding of our own sensory capabilities and interaction with the world?

It gives a fresh perspective on how specialised and limited our own view of the world is. We make so many assumptions that the world is really as we experience it, but we experience the world in a very specialised way. Sensory ecology provides lots of new information and facts about how other animals interact with the world, what governs their behaviour, but equally importantly sensory ecology questions very soundly our understanding of “reality”, what is the world really like as opposed to what we, as just one species, think it is like. This is quite challenging but also exhilarating. We really are prisoners of our own senses, and so are all other animals. Sensory ecology gives us the opportunity to understand the world as perceived by other animals, not just how we think the world is. That is really important since it injects a little humility into how we think about the way we exploit the world.

Could you give us some insight into how birds can use different senses in combination to refine their interpretation of the world around them?

Owls provide a good example. Their vision is highly sensitive but not sufficiently sensitive to cope with all light levels that occur in woodland at night, so owls also rely heavily upon information from hearing to detect and locate moving prey. The nocturnal behaviour of owls requires these two key sources of information but even these are not enough. To make sense of the information that they have available to them the woodland owls need to be highly familiar with the place in which they live, hence their high degree of allegiance to particular sites.  Other birds, such as ducks, parrots and ibises rely heavily upon the sense of touch to find food items. The degree to which this information is used has a knock on effect on how much the birds can see about them. So a duck that can feed exclusively using touch, such as a mallard, can see all around them, while a duck that needs to use vision in its foraging cannot see all around. This in turn has implications for the amount of time birds can spend foraging as opposed to looking around them, vigilant for predators. In many birds the sense of smell is now seen as a key source of information which governs not just foraging, but also social interactions.

Are there interesting examples of species that are specialists in one particular sense?

Usually birds rely upon at least two main senses that have become highly specialised and which are used in a complementary manner. For example, in ibises it might be touch and vision, in kiwi it is smell and touch, in some of the waders it is touch and taste, but in other waders touch and hearing.

Probably the most obvious single sense specialisations are found among aerial predators such as eagles and falcons, they seem to be highly dependent upon vision to detect prey at a distance and then lock on to it during pursuit. However, we really don’t know anything about other aspects of their senses and there is a lot left to learn about them.

Can you tell us about any species that you have studied that you find particularly fascinating?

Oilbirds; they are really challenging to our assumptions about what birds are, how they live and what information they have available to them.

Oilbirds are the most nocturnal of all birds, roosting and breeding deep in caves where no light penetrates, emerging only after dusk and then flying over the tropical rain forest canopy to find fruit. But they are a form of nightjar! In the complete darkness of caves they use echolocation to orient themselves and calls to locate mates. When searching for food in the canopy they use their sense of smell to detect ripe fruits, they have long touch sensitive bristles around the mouth. And their eyes have sensitivity close to the theoretical limits possible in vertebrate eyes.  They seem to rely upon partial information from each of these senses, and use them in combination or in complementary ways. They really are marvellous, but in truth the senses of any birds, and how they are used, are fascinating and intriguing, it is a matter of delving deep enough, and asking the right questions.

In what kind of direction do you think future sensory ecology research is headed?

We now have available a lot of techniques to find out about the senses of birds, from behavioural studies, to physiology and anatomy. Armed with these techniques, and also with ways of thinking and measuring the perceptual challenges of different tasks and different environments, there are so many questions to investigate. We have some fascinating findings but we have only just scratched the surface with regard to species and it does seems clear that senses can be very finely tuned to different tasks. I like to compare the diversity of the bills that we find in birds with the same diversity in the senses in those species.

Every bill tells a story about form and function, about evolution, ecology and behaviour. The senses of birds show the same degree of diversity and tuning. So to me sensory ecology is a wide open field with lot of questions to investigate. To appreciate the world from a bird’s perspective will, of course, give us a much better understanding of how to mitigate the problems that humans have posed to birds by shaping the world for our own convenience.

Birds of the Indonesian Archipelago: Greater Sundas and Wallacea is a new field guide dedicated to this major region which contains a massive 13% of the world’s avian biodiversity. Featuring over 2,500 illustrations, it describes all 1,417 bird species known to occur in the region.

Co-authors James Eaton and Nick Brickle share some of their birding insights and in-depth knowledge of the region’s avifauna in this interview with NHBS.

Could you tell us a little about how you became interested in birding and what drew you to this region in particular?

James – My Grandmother gave me a copy of Benson’s Observer’s Book of Birds when I was six, and, wanting to see some of the birds in the illustrations in real life, my father agreed to take me to the local nature reserve to look for them, and from that point on it became an obsession!

Nick – Similar story. I got hooked before I was 10 years old, partly thanks to Choughs, Peregrines and my dad’s old binoculars on family holidays to Pembrokeshire. Ten years later and I found myself surveying White-winged Ducks in Sumatra and never looked back.

What inspired you to create a field guide that covers the entire Indonesian Archipelago? It must have been quite a challenge to cover such a diverse region.

All four of us are pretty obsessed with the region’s birds, both as a hobby and professionally, and all of us have travelled pretty widely in the region over many years. During this time the region has gone from having no bird field guide at all, to having a variety of books covering different parts of it; some now already long out of print. We all decided it was time to put our passion into a project that could do justice to the spectacular diversity to be found here, and so agreed to work together to create the new guide.

Could you explain a little about the unique biogeography of the region which makes it such a biodiversity hotspot?

Hard to sum it up in a sentence! It’s a fantastic combination of Asian and Australasian bird families, spread across 1000s of islands, with Wallace’s famous line running down the middle, and spectacular endemism throughout. For more, read the biogeographical history section in the introduction to the field guide!

Who is your target audience for the book?

Birds of the Indonesian Archipelago: Greater Sundas and Wallacea

Anyone with an interest in the birds of the region! Visiting and resident birdwatchers are the obvious user, but given that it includes over 13% of the world’s birds, anyone with an interest in birds should enjoy it. In due course we also hope to produce an Indonesian language version of the guide, so as to make it more accessible to the growing number of local birdwatchers.

For someone visiting the area for the first time, what are some of the most exciting sites, and the key species that you recommend looking out for?

Where to start! Within Indonesia, the best places for an introduction are probably the mountains and forests of West Java, which are easy to visit from Jakarta, and where many of the most sought after Javan endemics can be seen; or perhaps North Sulawesi, where a trip to see hornbills, endemic kingfishers and Maleo can be combined with beaches and diving; or Bali, where one of Indonesia’s rarest and most spectacular birds – the Bali Starling – can be seen with a short trip from the beach resorts.

Another choice for an easy introduction is the Malaysian state of Sabah in the north of Borneo. Here many spectacular and endemic birds can be seen from the comfort of first-rate hotels, including Great Argus and the completely unique Bristlehead. After that, the opportunities are limitless!

How do you kit yourself out for a birdwatching trip to the region, and can you recommend a great birding gadget or app?

At the simplest, you don’t need much more than a pair of binoculars (and maybe a rain coat or umbrella!). Beyond that it depends a bit on where you are going and what you’d like to see: a telescope can be useful, but is rarely essential, sound playback or recording equipment can be very useful, a camera if you like to take photos, camping equipment if you plan to visit very remote regions. If you plan to explore off the beaten track (and there are lots of parts of the region that qualify as this!) then a phone and google maps can be a surprisingly useful way to look for patches of forest, and then all you need to do is try and make your way towards them!

Do you have any favourites among the species in the guide? Are there any that proved particularly elusive or challenging to observe?

James – Difficult question, can I give two answers? One would be Helmeted Hornbill. Such an iconic bird that symbolises the region’s rainforests. You know when you hear the bird’s incredible mechanical laughing call you are in the rainforest, but equally you are reminded how it is disappearing from many areas due to illegal hunting for its casque. Another would be Bornean Ground Cuckoo. Once a mysterious bird, largely unknown due to its shy nature, feeding on the rainforest floor, but now as our understanding of the species has grown it is possible to see it. Nothing gets the adrenalin pumping quite as much as looking for this species.

Nick – Too many to choose from! For me it would have to be something that walks on the ground… pretty much any pitta, pheasant or partridge is a candidate. Maybe Banded Pitta (any of the three species…)? Or the spectacular Ivory breasted Pitta? Then of course there is Rail Babbler… Actually, more often than not my favourite is the last new species that I have seen, or the next new one that I want to see!

With so many endemic species, there must be some that fill very specific ecological niches?

Endemism is very high in the region, and many species are only found within very small ranges, such as Boano Monarch on an island only 20km wide, or Sangihe Island, only 40km long at its widest point, and with five endemic bird species. Damar Flycatcher too, found in the dark understorey of a tiny island that requires two days’ boat travel from the nearest city. Kinabalu Grasshopper Warbler is only found on the top of two mountain tops in Borneo. When it comes to specific niches, however, small island endemics are often the opposite, in that they often expand their niche due to the absence of competitors. Birds filling very specific niches are probably more a feature of the large islands groups like Borneo and Sumatra, where the overall diversity is much greater.

It is quite well publicised that one of the biggest threats to the conservation of all Indonesian species is rapid deforestation to create palm oil plantations. Are there other threats to bird species which also need to be highlighted?

Deforestation is a big issue. There has been a huge loss of forest over the last decades, but vast areas still remain, and their value is finally starting to be more widely recognised. Hunting for the captive bird trade also remains a huge threat, particularly to those species most desired as pets, such as songbirds and parrots. Local and international groups are working hard to try and reduce this trade, in particular the public demand, but there is still much work to be done to change attitudes.

How can the international community help to support conservation efforts?

As birdwatchers one of the simplest and best things you can do is to visit the region and go birdwatching! Coming here, spending time, spending money, staying in local hotels, eating local food, using local guides, all serves to create a value to the forests and the wildlife that lives in them. This is not lost on local people or the regional governments. Beyond that think carefully about the products you buy from the region, to make sure they come from sustainable and fair sources. If you have money invested make sure that is not going to support destructive or exploitative practices in the region. Finally, support a good cause! There are many, many local NGOs established and emerging in Indonesia and the wider region, all working and lobbying hard to protect the region’s forest and wildlife. Your support will help them achieve this.
