It was observed that Cormorants roosted on Bamboo clump, Bombax ceiba, Mangifera indica, Syzygium cumini, Cocos nucifera, Tamarindus indica, Albizia procera, Acacia nylotica, Amoora rohituca, Swietenia mahogany, Dulbergia sissoo trees. Local small fish species like glassy fish, bele, tengra, shrimp, pale carplet, corica soborna, telapia, spotted snakehead, kakila etc. are the food materials for Cormorant in the study area. Most species (local birds) commence their nesting operations beginning of March but Indian Cormorant starts their nest July to September and laid two eggs of each pair.
