Abstract
Bird species diversity of the altitudinal belts of the Eastern Himalaya was analyzed in the early spring of 2005 and 2014. The species richness is decreasing from the belt of subtropical mixed and coniferous forests to the alpine belt. Specific species not beyond the borders of the appropriate belt are characteristic of three of four altitudinal belts. Avifauna of two adjacent belts also has a lot of common species. One hundred thirty three bird species registered in both seasons belong to 6 faunal complexes, the majority of species are Himalayan endemics and subendemics, as well as Palearctic species. Abundance of background species was determined for each altitudinal belt.
