Abandoned sites: Boon or bane for urban bird nesting-A case study from Tirunelveli, Tamil Nadu (India)

A short duration observation on birds' nesting in an abandoned bungalow premise in the heart of Palayamkottai, Tirunelveli district in Southern Tamil Nadu is reported as a case study.Three species of water birds namelyBlack-crowned Night Heron (Nycticoraxnycticorax), Intermediate Egret (Mesophoyxintermedia), and Little Cormorant (Phalacrocoraxniger) were found to show mixed roosting. Recently infrastructural modification of the premise was undertaken, which influenced the nesting site of these colonial birds, considering their high sensitivity to disturbance.
