Frank Lambert studied birds in Southeast Asian rainforests for his doctorate and in subsequent research. An avid world birder, Frank started his career working for various conservation NGOs, but in recent years has mainly worked as an international bird guide. Having lived in Asia for more than 20 years and travelled the globe in search of birds, Frank has seen almost all the species featured in this book.

Apart from seeing birds, Frank's main passion is to capture the sounds that they make. He has recorded the songs and calls of more than 5,000 bird species, most of which are freely available at xeno-canto.org.

The late Martin Woodcock was one of Britain's leading bird artists. A former chair of the African Bird Club, his greatest work was the art for the monumental Birds of Africa series, published between 1981 and 2007.

Martin was a great student of tropical birds, and his other works included the plates for Frank Lambert's Pittas, Broadbills and Asities, the second edition of which would be his final publication, with Martin completing the cover art before his passing in 2019.
