Abstract

The study started with an aim of preparing a Checklist of birds of Krishnanagar Govt. College, Krishnanagar, Nadia. A total of 30 species of birds belonging to 22 families were recorded in and around the campus of the College from January 2015 to December 2015.

Among the non-passerines, maximum richness was represented by the order Ciconiiformes (2 families, 3 species). Of the total diversity, 43.33% (13 species) are common, 30% (9 species) are Frequent and 20% (6 species) are occasional and 6.66% (2 species) are rare. Among the foraging groups, insectivores (30%) dominated the bird community followed by Omnivores (20%), Frugivores and Carnivores (16.66%), Fish eating and Granivores (6.66%) and Nectarivores (3.33%).
