These are superbly illustrated in 141 color plates with more than 2,000 full color bird images, including most of the sexual variants and immature forms of polymorphic species. Each plate is accompanied by species descriptions covering nomenclature, length, voice, range, distribution and status and habits, with distribution shown by detailed thumnail maps. There are seven habitat plates, 12 regional maps showing Borneo's top 130 birdwatching sites, fast-find graphic indexes to the birds of Kinabalu and other habitats and a full overview of vegetation, climate and ecology. Indonesians refer to Borneo as as "Kalimantan". However, for people outside of Indonesia, Kalimantan refers to the Indonesian part of the island of Borneo. Borneo is surrounded by the South China Sea to the north and northwest, the Sulu Sea to the northeast, the Celebes Sea and the Makassar Strait to the east and the Java Sea and Karimata Strait to the south. To the west of Borneo are the Malay Peninsula and Sumatra. To the south is Java. To the east is the island of Sulawesi (Celebes). To the northeast is the Philippines.
