Our leaders are a mix of Asian-based and Asian nationals, whom lead both our scheduled and custom tours.
On top of the broad range of scheduled tours offered, we offer a range of custom tours, whether it be extensions to the advertised scheduled tours, but also stand-alone tours. Using Birdtour Asia in-house expertise we can tailor the custom tours to suit your requirements. We use a number of locally-based guides for this, and are actively encouraging and promoting the use of young, keen guides throughout the region. Some of our most popular guides are below, though we also have several other guides who lead custom, private tours with us.

James Eaton - throughout the region

James's teenage years eventually led him to Asia, thinking nothing of skipping college lessons for a long trip with Rob to India!
Residing in Malaysia, he has built an enviable, intimate knowledge of the identification, vocalisations and behaviour of the birds throughout the whole continent. This has resulted in the discovery of at least five undescribed species to science in Indonesia (two now described!), as well as numerous rediscoveries during his visits to over 70 islands within the archipelago.
The culmination of his field-time has resulted in the publication of over 95 manuscripts and articles, over the past 20 years, and lead-author of the Birds of the Indonesian Archipelago.

James has a PhD, having studied taxonomically cryptic species and their conservation status. A keen conservationist, with a particular interest in trying to put an end to the bird trade through surveys and research, and a member of the IUCN Asian Songbird Trade and Hornbill specialist groups. On top of that, he is the eBird reviewer for Indonesia and East Malaysia.
Like all our leaders, James has more than a passing interest in the mammals of the region, and is attempting to see all of Asia's megafauna and primates (a very slow, drawn-out and often frustrating process!).

Rob Hutchinson - throughout the region

Rob began birding almost as soon as he could lift a pair of binoculars and foreign travel soon developed this into a passion for world birding, with a special interest in the birds of the Oriental region. Since graduating with a BSc in genetics he has travelled throughout the region, visiting many remote areas in search of the regions very rarest birds.

Rob is an accomplished photographer and keen sound recordist who has authored many scientific papers on the vocalisations, distribution and taxonomy of the region’s birds including several elevating little-known forms to species rank. His main interested is his adopted country of the Philippines where he has seen most extant species and co-authored A Naturalists guide to the birds of the Philippines, and is passionately involved in the conservation of the islands. His travels across the region have netted more than 2,800 species - likely more than anyone else - and he enjoys sharing his knowledge and enthusiasm with others.

Wilbur Goh - China, Southeast Asia

Wilbur is a Malaysian who started birding in his early teens, an obsession which has blossomed into a lifelong love affair with the region’s birds. Having travelled the length and breadth of the country for birding, Wilbur knows intimately the habits and calls of Malaysian birds. He has led numerous trips and field surveys as a member of Malaysian Nature Society, spending hours in the field honing his field skills, before deciding to be a full-time guide.

Birding in other countries throughout Asia has also helped him to broaden his experience, and though Malaysia will always be his specialty, he's one of the more experienced guides in Papua, and other areas of eastern Indonesia now. Whether in the field or out of it, he is always keen to share his knowledge and passion for the local avifauna.
His easy going, relaxed attitude, even during the most intense birding days has made him an extremely popular guide.

Shashank Dalvi - India

Shashank is a researcher, conservationist and entrepreneur from India with more than 20 years of field experience and an immense knowledge of the natural history of the country. His work has led to the discovery of the new bird species, Himalayan Forest Thrush, apart from several rediscoveries and range extensions across almost all vertebrate taxa in India. His research work on birds also includes understanding biogeographic barriers on population genetics and the impact of land use change on bird communities.

Shashank was also instrumental in exposing the mass-scale hunting of Amur Falcons in Nagaland and subsequently designing a conservation action for the species. In 2015, Shashank completed a Big Year in India, with 1,128 species seen just within the country. This led to him developing a mobile application called Vannya to get more Indians to actively start watching birds. The application is now used by more than 50,000 people across the world. For 15 years, Shashank has been juggling all his research, conservation and education work with guiding bird tours because he enjoys the challenge and the constant reminder of the reason he fell in love with India's wildlife. He is also the only birder to have spent time on all the main Nicobar islands, during his research projects over several months in recent years.

Mike Nelson - throughout the region

Mike has been a birder since he was six, when he became fascinated with the birds in his English garden. With a father in the oil industry, he grew up in the Middle East and the Caribbean, eventually settling in the United States in 1980. Having lived in and travelled to over 40 countries he is an experienced world birder and as an avid sound recorder, he has logged over 12,000 sound recordings.

Mike developed a particular interest in Asia during his birding travels and having led numerous tours in Asia, working as a full-time guide for Birdtour Asia was a natural progression to share his knowledge and enthusiam on tours throughout our region. He is now a firm favourite on several of our tours where he now spends far more time on tours than he does at home!

Yeo Siew Teck - Borneo

Born and raised in the Malaysian state of Sarawak in Borneo, it was little surprise that Yeo grew up influenced by the natural world. He was involved in numerous expeditions to remote areas of this rich island, and he can include the rediscovery of Black Oriole among his achievements. Although his first love has always been birds he is renowned for his all-round expertise in Borneo’s organisms, including finding a new species of pitcher plant, Nepenthes appendiculata, and was the first person to record the sound of a rare, fossorial frog species - Gastrophrynoides borneensis.

Yeo is a keen conservationist, heavily involved with the Malaysia Nature Society and the Sarawak Forest Department, for whom he surveys the states National Parks. A Sarawak tour with Yeo will not only be productive birdwise, but an all-round nature experience as he enjoys sharing his knowledge with participants.

Wichyanan Limparungpatthanakij - Thailand

Growing up in Thailand's lush countryside, Jay has been a wildlife enthusiast for as long as he could remember. As a young kid he explored the seasonal floodplains armed with a pair of cheap plastic binoculars and the famous Lekagul & Round's field guide published in 1991. Bird identification has become one of his lifetime obsessions, culminating in the publication of Birds of Thailand in 2018, which he co-authored with the renowned Uthai Treesucon.

Having seen over 940 species in Thailand, he's the regional eBird reviewer for Thailand, and a member of both the Thai and Philippine Rarities Committees. On top of his, he studied his MSc on the ecology of mixed-species flocks, and is an avid researcher, his publications can be viewed here.

Khaleb Yordan - Indonesia

Born and raised in the metropolis of Jakarta, Khaleb was soon venturing outside of the urban sprawl while still a kid, where he soon gained an appreciation for birds and mammals. Since then he has gained an intimate knowledge of the endemics and specialities of Java, Bali and Sumatra with a particular emphasis on west Java, where he has shared many of his adventures with his brother, Boas.

He has been involved in several bird research monitoring projects, including taking boats off Java for Burung Laut Indonesia as a member of the Seabird Working Group, and avifaunal studies in the Moluccas. Khaleb is the perfect guide for custom tours throughout Java, Kalimantan and Sumatra, and increasingly the rest of Indonesia as he's now becoming increasingly experienced in Papua and Wallacea.

Martin Kennewell - Eastern Palaearctic

Martin, like the rest of us, has been a birder since childhood, cutting his teeth around the gravel pits of the Trent Valley in Nottinghamshire. His travels have taken him to all parts of the globe and he’s amassed well over 8,000 species worldwide.

For nearly 20 years he’s been based in Asia, mostly in Singapore where he was involved in the discovery of several country firsts and numerous other rarities. This gave him the opportunity to travel extensively throughout Asia and build up an excellent knowledge of the region which he now shares on several Birdtour Asia tours with a focus on the Eastern Palearctic including Middle East, across to Mongolia, China and Japan.

Following his early retirement (from his professional work, not birding!) he lives with his family in the Philippines where he is already an active member of the birding, Odonata and Lepidoptera communities.

Otani Chikara - Japan

Otani was born and raised in Tokyo, with a few years in London during his formative years. His loves for nature and birds began in childhood and he's been studying and enjoying birds ever since.

After graduating from the University of Tokyo, his life has evolved around nature, working as researcher for nearly 40 years and as a bird guide for much of that time. His passion has led him across the world in pursuit of birds (even rediscovering Roborovski’s Rosefinch in the process!), though it’s in Japan where his in-depth knowledge has been of most value, culminating in him authoring the ‘Birds of Japan’ field guide.

With such a background, Otani is the perfect guide to make any birding trip to Japan a memorable experience.

Sayam Chowdhury - Bangladesh
