COMMENSAL ASSOCIATION IN PISCIVOROUS BIRDS

摘要

Studies on habitat use and foraging ecology of piscivorous birds were made on Nyari-I reservoir from September 1998 to October 1999. Foraging association between mass foraging cormorants and terns was recorded. The association was widespread in otherplaces as well. We could also observe Dalmatian Pelican, Intermediate Egret, Little Egret associating with mass foraging cormorants. We present indices of association to show the significance of association and also brief the significance changes in thebehavior of species joining mass foraging cormorants.
