The Western Himalaya is recognised for its biological diversity and ecological values. An attempt was made to understand the avian diversity distribution in Forest, Agriculture and Water stream habitats of Dehradun (Western Himalaya) Uttarakhand. A total of two hundred and thirty one species belonging to 54 families were encountered during the survey. Out of these, one endangered species (Egyptian Vulture, Neophron percnopterus) and three near-threatened species Alexandrine Parakeet (Psittacula eupatria), Black-necked Stork (Ephippiorhynchus asiaticu) and River Lapwing (Vanellus duvaucelii) and one vulnerable species Woolly-necked Stork (Ciconia episcopus) were sighted. Three avian species, Mistle Thrush, Sulphur-bellied Warbler and White-rumped Munia. have been recorded as isolates in the study area. The presence of these species indicates the habitats extension in Dehradun District of Uttarakhand. The present study provides significant records in the study site and provides a baseline data for future study with reference to conservation in Dehradun Region.
