"A Field Guide to the Birds of Borneo" is the first comprehensive and accurate guide to the varied avifauna of this island biodiversity hot-spot, which comprises Brunei, the Malaysian states of Sabah and Sarawak, and the Indonesian states of Kalimantan. More than 630 bird species have been recorded in Borneo and, using the most up-to-date taxonomy and nomenclature, the guide includes all recently split species and also gives full coverage to the distinctive Bornean races where they differ from their counterparts on neighbouring islands or in mainland South-East Asia. Borneo is of particular ecological significance; the unique combination of its tropical latitude and the relief of the land, which includes high mountains and rainforests, has created many isolated micro-habitats which have enabled a remarkable number of different species of birds to evolve, many of which are endemic to the island. Every species recorded is described in detail with key identification characteristics and habitat information given, plus a colour distribution map. All species are illustrated in the 246-page full-colour ID section, with paintings by the same expert team of artists who worked on New Holland's celebrated "A Field Guide to the Birds of South-East Asia".
