Ecological investigation of species diversity and abundance of birds was conducted from May 2014 to February 2015 in and around North Orissa University Campus. Transect count and point count methods were used to investigate the abundance of birds. Observation was conducted by periodically walking along the study area early in the morning and late in the afternoon. Different diversity indices and statistical methods were used to analyze data collected during the field survey. A total of 130 bird species grouped under 94 genera and 50 families were recorded. Terrestrial habitat contributed much in terms of species composition (74.09%) than aquatic habitat (25.91%). We observed that terrestrial habitat had higher number of birds (589 individuals, 79.23%) than water birds (206 individuals, 20.77%). Shannon's diversity index indicate that terrestrial habitat had higher species diversity (H’ = 3.421) than aquatic habitat (H’ = 2.222). The overall birds’ diversity for both terrestrial and aquatic was (H’=3.707). Appropriate management of bird attractant sites is very important to discourage birds from the university campus
