The birds of Thailand represent nearly one thousand species. At least seven bird species previously found in Thailand have since been extirpated, and approximately fifty of the country's species are globally threatened. In 1991, it was estimated that 159 resident and 23 migratory species were endangered or vulnerable due to forest clearance, illegal logging, hunting and habitat degradation, especially in the lowlands. The birds of Thailand are mainly typical of the Indomalayan realm, with affinities to the Indian subcontinent to the west, and, particularly in Southern Thailand, with the Sundaic fauna to the southeast. The northern mountains are outliers of the Tibetan Plateau with many species of montane birds, and, in winter, the avifauna is augmented by migrants from the eastern Palearctic and Himalayas. The Java sparrow has been introduced by humans, and the cattle egret (pictured) has naturally colonised. The white-eyed river martin, known only from its single wintering site in Thailand, is probably extinct. (Full list...)
