Abstract

Breeding season of avifauna is initiated from mating choice and nesting step. Nest is an important aspect in cormorant survivability. Prior entering breeding season, male cormorant construct nest to lure the females. Size and composition of nest directly determine the success of breeding and birdlings survivability. In this study, we examined nest constructions within 5 plots consisted of 15 stands for nest occurrence and 10 stands for nest characteristics at Tanjung Rejo, Deli Serdang, North Sumatera. The results showed that black cormorant preferred to place their nests on 4 stand species: Exocoecaria agallocha, Rhizopora apiculata, R. mucronata,and R. stylosa. Black cormorant nests shaped like concave bowl and placements are not considered specific to certain site of stands. Twig characteristics are from straight-branched, straight-unbranched, branched, falciform-branched and falciform-unbranched. The conclusion of this study is that selection upon nest tree species, placement and structures are important part of the breeding success of black cormorant.
