Abstract: The study aims to explore the diversity of breeding birds in the main urban green areas of Lhasa. The investigated composition of the bird community was collected by direct counting method from seven observation points of five urban green areas/ parks (Longwangtan Park, Potala Palace Square, Norbulingka Park, New Campus and Old Campus of Tibet University) in May and June from 2016 to 2019. 46 species (belonging to 10 orders and 24 families) were recorded. For the bird fauna, there are 39, 6 and 1 species that belong to the Palaearctic, Oriental and Cosmopolitan species respectively. For the resident type, there are 31, 14 and 1 that belong to resident, summer visitor and passage migrant birds, respectively. Considering habitat and spatial distribution the bird diversity index in forest and lake areas are relatively high. The fluctuant results indicate that urbanization may have had certain impact on the diversity of bird population in urban green area of Lhasa.
