Abstract
A study was conducted on the nesting behaviour of Indina Pond Heron in Sitakunda, southeastern region of Bangladesh between January, 1995 and December 1996. Indian Pond Heron is a solitary bird on its feeding grounds. It forms colonies when nesting. Eight species of plants were used for nest building in three colonies. Colonical nesting is an anti-predator adaptation in the Indian Pond Heron.
