Avifauna in two different residential localities of Kolkata viz. Cossipore of North Kolkata and Dhakuria of South Kolkata was done in twelve months period from December, 2013 – November, 2014 to get some idea about the present avian diversity of the city. Total forty eight species of birds belonging to twenty five families were identified from the two sites and recorded along with their abundance in this study. Fluctuations in abundance of bird fauna between the study areas were also recorded which may be attributed to the loss of proper habitat for foraging and nesting due to continuous urbanization and increased pollution rates.
