The late Clive F. Mann (1942–2022) taught biology in schools in Africa, South-east Asia and England. During the course of extensive fieldwork carried out during long sojourns in the tropics, he studied the population dynamics, breeding cycles, zoogeography and migration of birds, and the subject of his PhD was the taxonomy of passerines. Clive was a Fellow of the Linnean Society and a member of the British Ornithologists' Union, and he served for many years on the Committee of the British Ornithologists' Club, becoming its chairman from 2001 to 2005. He was also a trustee of the Trust for Avian Systematics (previously the Trust for Oriental Ornithology) for more than 20 years. He wrote numerous papers in scientific journals, The Birds of Borneo BOU Checklist and was a co-author of the Helm Identification Guide: Cuckoos of the World.
Robert A. Cheke is Professor of Tropical Zoology at the Natural Resources Institute of the University of Greenwich. Before university, he qualified as a grade A bird ringer and worked as a field assistant at the British Trust for Ornithology. After graduating with a PhD in zoology at the University of Leeds, he held various posts in academia before becoming employed at the Centre for Overseas Pest Research (then part of the Ministry for Overseas Development). Robert's work has frequently taken him to sub-Saharan Africa, where he has been able to follow his passion for sunbirds. He is the co-author of The Birds of Togo (1996), has edited or co-edited six further books and published more than 500 scientific papers. Robert was awarded a DSc by the University of Greenwich for his extensive research work in 2021.
Richard Allen won the British Birds Bird Illustrator of the Year award in 1993, and since then his work has appeared in various books and journals including Sunbirds, Cuckoos of the World and Birds of Paradise and Bowerbirds. He lives on the Essex coast and often escapes the studio to sketch the waders and wildfowl that throng the local estuaries. Richard was elected to the Society of Wildlife Artists in 2016 and he won the Birdwatch and Swarovski Optik Artist of the Year award in 2023.
