The Kathmandu Valley, encompassing the capital city of Nepal, is one of the fastest growing metropolitan areas in South Asia. Rapid population growth and urbanization in Kathmandu have degraded the urban environment affecting the native biota. Therefore, a detailed assessment of avian species richness and its distribution in potential green spaces of the Kathmandu Valley is essential. We assessed the avian diversity in different habitats of the Tribhuvan University area, a potential refuge for birds in the urban landscape, by the point count method in the winter and summer of 2020. A total of 71 bird species from 39 genera and 32 families comprising 10 orders - ‘including the globally endangered Steppe eagle (Aquila nipalensis)’ - were recorded. Of the 10 orders, Passeriformes (44 species), had the highest richness followed by Columbiformes, Piciformes and Cuculiformes (with four species in each). Among the feeding guilds, the insectivorous guild (with 28 species) had the highest species richness followed by omnivores and carnivores. A higher Shannon’s diversity index was recorded in forest habitats (3.51) than built-up areas (3.45) or farmland (3.42). Despite the small size, our study has shown that the Tribhuvan University area is an important greenspace for birds in the Kathmandu Valley. An extensive exploration, monitoring and management of greenspaces are crucial for maintaining the ecological integrity of the urban landscape of the Kathmandu Valley.
