This is the fully revised and updated third edition of an acclaimed field guide to the birds of Borneo, covering Sabah, Sarawak, Brunei, and Kalimantan. The result is the most up-to-date, comprehensive, and user-friendly guide to the island's remarkably diverse birdlife. The book covers all 673 species living or reported on Borneo, including all 59 endemic species. Each species is superbly illustrated in 141 color plates containing more than 2,000 full-color bird images, which provide multiple large views of each species, including most of the sexual variants and immature forms of polymorphic species. Each plate is accompanied by facing-page species descriptions covering taxonomy, size, call, range, distribution, habits, and status. Distribution is also shown with 567 detailed color thumbnail maps on facing pages. Other features include seven habitat plates, twelve regional maps showing Borneo's top 90 birding sites, fast-find identification plates to the birds of Kinabalu and other habitats, and a full overview of Borneo's vegetation, climate, and ecology. This is a guide that any outdoor visitor to the island will treasure.
