贾瓦哈拉尔·尼赫鲁大学校园是一个独特的campus which habours not only the natural ridge ecosystem but also a huge avifaunal biodiversity. The survey was done for a period of three years from January 2013 to December 2016. Data was collected using line transects in different habitats all across the campus. A total of 114 bird species belonging to 19 orders and 52 families were identified during the study period, including 3 near threatened species, 2 vagrants, 3 summer visitors, 4 passage migrants, 26 winter visitors and 79 resident species. Of these, 47 species were insectivorous, 33 species were omnivorous, 14 species were carnivorous, 7 species were frugivorous, 6 species were gramnivorous, 4 species were herbivorous, 2 species were piscivorous and 1 species was nectarivorous. It was observed that the Jawaharlal Nehru University campus supported very rich and diverse avian fauna assemblages all year round due to the presence of the ridge ecosystems. Long-term conservation programmes must be adopted in order to protect the natural ecosystems and bird diversity present in the campus.
