The birds of Thailand included species as of Of them, 7 have been introduced by humans, and eight have been extirpated. 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. That Thailand's habitats are contiguous with those of neighbouring countries explains the low number of endemic species. In , it was estimated that resident and 23 migratory species were endangered or vulnerable due to forest clearance , illegal logging , hunting and habitat degradation , especially in the lowlands.
The species most affected are large water birds whose wetland habitat has been largely lost to agriculture, and forest species, as deforestation for agriculture and logging have removed and degraded portions of the woodlands.
