Identification

POWERED BY MERLIN

A distinctive white swan with a bright, rather ducklike bill. The black wingtips are usually concealed when swimming. Most likely to be confused with white domestic waterfowl. Fairly common but sometimes local on lakes, slow-moving rivers, wetlands with open water, estuaries, and inshore coastal waters. Often in groups and associates readily with Black-necked Swan. Cygnets are dirty brownish with a black face mask, but young look much like adults within a month or two after hatching. Name comes from slightly gruff, honking “kós-ko roa” call.
