Black-vented Shearwater


(Puffinus opisthomelas)

Black-vented Shearwater is the smallest commonly seen shearwater off the Pacific coast, where it not uncommonly ventures to within a few miles from shore, often in large flocks. It is easy to recognize with its dark vent sharply contrasting with its clean white underside. The dark legs and dark bill further distinguish it from the also common Pink-footed Shearwater which has pink legs and pink bill. Manx Shearwater is similar in size, but has a white vent and occurs in the Pacific only in very small numbers.
