Vultures are a crucial part of many of the world’s ecosystems, and without these specialist environmental cleansers many ecosystems wouldn’t function. In A Vulture Landscape we share a calendar year in the lives of these gargantuan raptors as they live, breed, feed and fly with effortless ease across the skies of the vulture landscape that is Extremadura in central Spain.

Author, Ian Parsons visited us at NHBS to answer some questions about these often maligned birds and also *signed a limited amount of copies of his new book.

*All signed copies have now sold

Could you tell us a little about your background?

I was born and grew up in Devon in south west England, as I grew up I became more and more interested in the natural world, I can remember becoming fascinated by slow worms when I was around seven years old, although I also remember my mum’s slightly horrified reaction when I happily brought one into the house to show her. I wanted to be a Ranger from an early age and after a countryside management course at college I became one for twenty years. When the time was right for a change, myself and my wife moved to Extremadura in Spain where we set up Griffon Holidays, running specialist bird tours in this amazing region that I had first discovered almost twenty years before.

Why did you chose to write about vultures?

Because they are brilliant! I am a massive natural history fan and geek and I’m passionate about all types of wildlife, I would say that trees and birds are my two main interests and when it comes to birds there is nothing like a vulture. Watching birds with a nigh on three metre wingspan gliding right past you is an amazing experience, they are masters of the air and take flight efficiency to the extreme, they can read the air and its movements and to watch them is mesmerising. In the book I mention several times how my favourite past time is Vulture Gazing, just sitting back and watching them drift across the blue sky above you, it is a great way to declutter your mind, everyone should vulture gaze!

What’s special about Extremadura and its fauna and flora?

Extremadura is a region in western Spain, it is roughly twice the size of Wales, but with only one third of the human population, it is relatively empty of people and full of amazing wildlife. It has long been known as a bit of a destination for birders and rightly so. There are Great and Little Bustards, two species of Sandgrouse, colourful stars such as the Blue Rock Thrush, Roller and Bee-eater, NHBS’s very own Hoopoe is abundant and then there are the birds of prey, five species of eagle, three species of kite, falcons, harriers etc. And of course there are the vultures, the Griffon Vulture, Black Vulture and Egyptian Vulture, the skies always have something interesting in them.

Spending time on the flower rich plains in the spring listening to the wall to wall surround sound song track of abundant larks whilst raptors drift by overhead is one of life’s pleasures.

What were the major challenges you faced while writing your book?

I think the biggest difficulty is knowing when to stop! When you are passionate about something it is very easy to get carried away.

What impact has Covid had and will continue to have on eco-tourism?

It has had a massive impact. I had to cancel the tours for 2020 which were fully booked, personally it is heart breaking to have to tell people that their trip which they had been really looking forward to is off. But everybody knew why the decision had to be made. I always put the clients up in a lovely Spanish town in a local family run hotel, they are lovely people and they are having to endure a really bad situation. As to the future? Who knows, the situation is so unclear at the moment, it is impossible to make any real plans.

Is it fair to say that vultures have a bit of an unfair reputation?

Vultures are associated with death, it’s what they do, they are scavengers and they eat dead things. We humans don’t like the subject of death, we actively avoid it and therefore anything that is associated with it tends to be seen in a negative light. But vultures need to be seen in a positive light, many of the world’s vulture species are critically endangered, the last category before extinction, they are in that position because of us. Vultures do an incredible job, they are nature’s environmental cleansers and they help keep ecosystems healthy and functioning, they can deal with diseases like bovine TB, rabies and even anthrax, they remove these diseases before they can become a threat to us, they help keep people safe. We should celebrate them and most certainly enjoy them, I hope my book will go some way to helping improve the image of these brilliant birds.

Recently a Bearded Vulture has had an extended stay in Britain, is this normal?

It’s not normal, it is only the second time that one of these majestic birds has been recorded in Britain (in 2016 one briefly visited Devon and South Wales). Vultures are not native to Britain, the climate for one thing is not conducive to them and it is noticeable that after an extended stay in the Peak District the bird has started moving south and east again now that the seasons are changing. Their appearance is the result of some fantastic conservation work carried out in the Alps where the bird has been successfully reintroduced after being persecuted to extinction over one hundred years ago. The new population is absolutely booming, and wild born young are being born in good numbers each year, in 2019 39 young successfully fledged. Vultures like the Bearded don’t breed until they are around five years old and after they become independent the young birds like to wander. For a vulture, distance is rather irrelevant, they often fly several hundred kilometres in a day’s foraging, and it is one of these young birds that has turned up in Britain this year, but the bird is just an avian sightseer and hopefully it will return safely to its natural range before very long. Whilst it will remain unusual for these birds to turn up in Britain on their travels, the continued success of the conservation work in the Alps means that there will be a chance that other wandering young will follow in the future.

After a well-earned rest, are there any plans or works-in-progress that you can tell us about?

I am currently involved in a great new project that aims to rewild your inbox! Purple Crow sends out a mixture of great photography and great writing to your inbox throughout the week, the idea is to inspire people with stunning images and inspiring words, see purplecrow.co.uk for more details. Book wise I am working on a book looking at the wildlife of Britain through the seasons.

Once a familiar sight motionless above road verges, the population of kestrels has sharply declined, a decline which continues as the intensification of agriculture and the populations of other raptors increases.

Richard Sales comprehensive new study investigates the decline, after first exploring all aspects of the kestrels’ life, from plumage and diet through breeding to survival.

The book includes data from Richard’s recently completed four-year study in which video cameras were installed to watch breeding behaviour in a barn in southern England.

Richard visited us to sign copies of his new book and answer our questions about how his expertise in physics and engineering have been used to find out more about this illustrious falcon.

Could you tell us a little about your background?

I am from Somerset and have maintained my West Country accent all my life, though I haven’t lived there for many years. I did physics as an undergraduate, then did an MSc in theoretical physics (studying energy loss from general relativistic stars), then a PhD in astrophysics flying a large (50kg) gamma-ray telescope suspended under a 3 million cubic foot balloon filled with hydrogen. The telescope flew at 105,000ft and discovered the first-ever gammar-ray pulsar. I then worked as a glaciologist in Switzerland for a while, and then took a job in the UK power industry.

When did you develop an interest in birds?

My father was bird lover and tailored our family holidays around the breeding season, so we went to Exmoor to watch buzzards and so on, rarely going anywhere near a beach and more often than not learning how to survive in poor weather. Both my brother and myself believe we owe our interest in birds to those trips. My father taught us how to watch birds, not just to learn their names so we could impress other people, but to really watch them. That has stayed with me ever since. I was more academic than my brother (who is a chemist – not a pharmacist, a chemist) and Dad wanted me to study zoology, but I chose physics. I also chose climbing as a primary hobby when I was teenager, first rock faces, then mountains, which is why I finished up in Switzerland when I was offered a post that allowed me to live at the Jungfraujoch and climb every weekend.

We lost our grant money in Switzerland, so I had to find another job. But as the years went by birds became more and more important to me. The dual love of birds, and snow and ice drew me to the Arctic and eventually I took very early retirement – I was only in my 40s – so I could spend more time travelling in the Arctic, supporting myself by starting a physics consultancy and writing books. One of the first Arctic-based books was a Poyser on Gyrfalcons which I co-authored with a Russian friend, Eugene Potapov. For that book I was watching gyrs in the Canadian Arctic. There was breeding pair and I watched the male hunting Arctic Ground Squirrels. He was coming from very high and a long way off and I noticed that he was not travelling in a straight line and couldn’t understand why not since the shortest route is the quickest. That lead me to investigate the eyes of falcons and also to build my own Inertial Measurement Unit (IMU) so I could track hunting falconry birds.

Has data from the Inertial Measurement Units (IMUs) you have developed been used in your books?

I flew my first generation IMUs on all four UK breeding falcons – each time on falconry birds. The unit I flew used the satellites to give me track position and had a barometer for height data (as height from satellites is only accurate if there are a lot of satellites in view, which is sometimes not the case on Scottish moors where I was flying on peregrines). The IMU also had a tri-axial accelerometer, gyro and magnetometer. All the data was stored on a flash drive on the bird so I crossed my fingers each time I flew one that the bird would come back.
In 2018 I co-authored a monograph on Steller’s Sea Eagles, the world’s largest eagle, with two Russian colleagues, and was lucky enough to find a captive Steller’s in this country which I could fly the unit on. That was a seriously interesting time. Steller’s are huge. I remember seeing them for the first time in the wild – in Kamchatka – which was awesome, but the size only became apparent when I saw them above sea ice over the Sea of Okhotsk when they flew with White-tailed Eagles. The White-tailed Eagles are the biggest raptors we see over here, but they were dwarfed by the Steller’s.

I also flew the unit on Merlins for the book published earlier this year. By then I was flying second generation units. These are much smaller, weighing only 3g, and much faster, tracking at 13Hz and collecting tri-axial data at up 1.6kHz. How much I can reduce the weight is important because every additional gram affects the bird in some way, and so particularly for Merlins getting the weight down is vital. Speed of data acquisition is also important because Hobbies, for instance, are incredibly agile and so the unit has to be fast to follow every twist and turn. Flying on a hunting Merlin was a strange experience. On the first flight we put the IMU on, released the bird and it flew 60m and attacked a Blackbird in a hedge. After a short fight the Blackbird escaped. For the rest of that day and several other days, the Merlin didn’t catch anything.

Why did you choose Kestrels as the subject for your latest book?

The UK is very lucky in the four falcons we have as breeding species. Peregrines are renowned for their high-speed stoops, Merlins for their fast chases and ringing flights, Hobbies for their agile flights after dragonflies and Kestrels for their ‘hovering’ search for mammals. A different hunting technique for each. I was particularly interested in Kestrels as in hovering – the official term for the technique is now ‘flight-hunting’ – the head must be held stationary for successful hunting so the body has to absorb the phenomenal forces caused by gravity, beating wings and the drag of gusting wind. I was anxious to investigate how they did it.

Did you encounter any challenges collecting data for your new book: Kestrel?

It required a lot of very sensitive equipment and some skilled operators. We borrowed two hi-speed cameras insured for £250,000 and set them up head-on and side-on to a flight-hunting falconry male Kestrel which carried the IMU. The cameras were running at 800fps and were filming 4k images, vast amounts of data were being collected and stored. The unit on the bird was collecting tri-axial data at 800Hz. It was also collecting satellite timing data, so to align wing, eye and head position we had to have a special time code generator which took a signal from the same satellites and stamped each frame of the film with a time measured in microseconds. The results are impressive in terms of how stable the head and eye position are. We are now preparing a paper for the scientific literature of body orientation relative to head position. It would have been good to have had that in the book as well, but the maths is so complex it is hard to make it easily accessible.

Your book features a four-year study to observe breeding behaviour; can you tell us anything about the methods and findings?

For four successive years we set up an array of video cameras filming breeding Kestrels in a barn in Hampshire. We had one camera filming the comings and goings of the adults and, later the fledglings, and two cameras in the nest box watching egg laying, incubation, hatching and chick growth. We filmed 24 hours every day, turning on IR lights to film at night. We measured egg laying intervals to the nearest minute, found accurate hatch times and watched every prey delivery. We also set up live traps where we knew the male hunted so we could weigh the local voles and mice and estimate how many kgs of rodent it takes to make 1kg of Kestrel. The filming was interesting – over the years the adults brought in slow worms, lizards, frogs and moths, as well as voles, mice and shrews. One male also brought in a weasel. This has long been suspected, but never-before filmed.

Can you tell us about any projects you are currently working on?

Because of COVID there is less money about, and writing books also takes lots of time and hard work. I have already decided I will not do a Peregrine book as there are already enough on the market (though none of them cover flight dynamics the way I would). I had planned to do a Hobby book because their flight is so fascinating, but if 2021 is another COVID year l might not be able to.

This comprehensive, clearly illustrated field guide, looks at all 815 bird species of Malaysia and Singapore. The main identifying features of each species are described and key facts cover size, voice, range and status and habitat. Distribution maps provide a view of where the birds can be found. The book also includes information on taxonomy and nomenclature, the breeding cycle, migration, conservation and key bird-watching sites of the region. This guide is essential for any naturalist interested in this region of the world.

Recording and observing such a rich diversity of birds, with over 800 species of birds including endemics in abundance is a huge undertaking.  How does such a daunting project come to fruition?  We asked contributors: Lim Kim Seng, Yong Ding Li and Lim Kim Chuah to answer some questions about themselves and the creation of A Field Guide to the Birds of Malaysia & Singapore

 Can you tell us a little bit about your backgrounds within ornithology and conservation?

Kim Seng – I started birding when I was about ten years old. I grew up in a family farm in Sembawang, in the northern countryside of Singapore. Together with my four other brothers, we explored the streams, hills and swamps and grew to love nature. One day, I saw a large kingfisher with a brown head, bright red beak and blue wings. It was my first Stork-billed Kingfisher and I was hooked. I was able to identify it through a book that I found in our National Library Natural History Section. Five years on, I joined the then Malayan Nature Society (now Nature Society (Singapore)) as a student member and just four years later, I led my first official society birdwatching outing at Rifle Range Road, together with my other birding brother Kim Chuah. With the help of other dedicated members, I learned a lot and was able to play my part in nature conservation, documentation, research and outreach, and have been an active member since then.

Ding Li – I have been birdwatching since my primary school days, after finding what I later discovered, to be Magpie Robins near my home in Kuala Lumpur. Subsequent visits to the mangroves of Kuala Selangor introduced me to the colourful world of birdwatching. Through various research projects, I have professionally studied birds in diverse settings ranging from Malaysian rainforests and the mountain forests of Sulawesi (Indonesia), to Australian woodlands. I now work full-time for BirdLife International, coordinating projects on bird conservation in Southeast Asia.

Kim Chuah – I grew up in a farm in rural Singapore in the ’60s and the surrounding woodlands and marshes were my playground. During my many sojourns into the wilderness, I started to notice some of the birds that lived around me – White-breasted Waterhen, Yellow-vented Bulbul, Common Tailorbird etc. That’s how I became interested in birds and it became my life-long passion. I’ve been volunteering in the Bird Group of the Nature Society (Singapore) since I was an undergrad. I participated in many of the birdwatching activities organized by the Bird Group including regular bird census and bird surveys. The data we collect helps towards a better understanding of birdlife in Singapore and is useful in building our case for better protection of habitats in Singapore.

How long has this project been in the making?

Kim Seng – My friend Dana Gardner, the illustrator of this book, got me interested in doing another book. We had successfully collaborated on a first field guide to the birds of Singapore in 1997 and were keen to work together again. Dana had a friend who was a publisher and we decided to a do a single volume field guide to the birds of the whole of Malaysia, since none existed. This was in 2010. Unfortunately, our publisher pulled out not long after that and we were left stranded. Luckily, through my fellow collaborators – Kim Chuah and Ding Li – we managed to get John Beaufoy interested in our project. A contract was signed in 2016 and as they say, the rest is history!

 What was the biggest challenge in creating this field guide?

Kim Seng – Each of us had different ideas on how to do the book and also other personal commitments. We as the writers also had to contend with differences in writing styles. Luckily, we decided to stick with a standard format, came up with a list of who was writing what chapters and what bird families and managed to more or less stick to our deadlines. Another challenge was the impressive work done by our illustrator. He had to do illustrations of all 829 species all by himself. To ensure accuracy, he would send us completed plates for comment, and we duly responded if changes were needed. Not an easy task, as we were based in Singapore and he, in the USA.

What features do you hope will make your field guide stand out from any others?

Kim Seng – This book is compact and contains all the necessary information you need to identify any bird species you see in the listed countries. The text is crisp and the illustrations accurate and there is also a detailed site and habitat guide to get birders to the most interesting places quickly and see those fascinating birds, based on the authors’ many years in the field.

Have the travel restriction due to COVID – 19 presented any threats or opportunities for the avifauna of Malaysia and Singapore?

Kim Seng – Well, COVID-19 has placed tremendous restrictions on travel in both Malaysia and Singapore. You could bird in certain areas but only with social distancing and other safe practices in place. Initially, we could only look at the birds from our balconies or backyards but this was an opportunity for some of us to study some of the neglected urban birds and understand a little better. I actually published two blogs based on my observations of urban birds from my balcony! In the last couple of months, restrictions have been eased and we are allowed to go birding in our favourite birding places, but I’m still waiting for the day when I can travel freely and bird in Malaysia again.

 Do you think eco-tourism is beneficial to conservation?

Kim Seng – Definitely. I believe ecotourism brings a lot of attention to the tremendous beauty and biodiversity of the natural habitats in both countries. It also brings revenue and employment opportunities to the local community who in turn will help to protect these wonderful places for a long time to come.

 What in your view are the best reasons to visit Malaysia and Singapore if you are a birdwatcher or an ornithologist?

Kim Seng – Three reasons – good birds, good food and good company. All three are never in short supply in these two amazingly friendly countries. The people are generally very friendly and the variety of local food is really incredible. Of course, the fascinating diversity of birds, with over 800 species of birds and Bornean, Peninsular and Sunda endemics in abundance are dreams to savour for birdwatchers and ornithologists alike.

Are you working on any other projects you can tell us about?

Kim Seng – I am currently working at putting up an adult learner’s module or course on “Birdwatching for Beginners”. It’s something I had worked on in the past and I want to continue my work in getting people of all ages interested in birdwatching as I believe it is a healthy and useful pastime. It should be fun as there are outdoor trips as well.

Ding Li – I am currently working with a team of designers to develop a board game on the migratory bird species of Asia. Such a concept to promote bird conservation has not been done in this region, so I am quite excited to see the final project materialise. I am also working with a team of international researchers to review the state of all of Asia’s migratory birds. If all goes well, this will be published in early 2021, and will bring together lots of new insights from all over the region and how migratory birds can be better conserved.

Kim Chuah – I am currently organising the 36th Singapore Bird Race. It will be interesting to see how we can organise the race during this pandemic. We will use the social media and available digital tools to make the race as exciting as in previous years. I am also working on action plans to better protect and conserve the critically endangered Straw-headed Bulbul in Singapore.
