Galapagos Shearwater

Puffinus subalaris

Very small black-and-white shearwater of warm tropical waters. Can be seen from shore off the coast of Oaxaca. Often in flocks, sometimes of thousands, resting on the water and in feeding flocks with Brown Boobies, Black Terns, and other shearwaters. Flight quick and low, with hurried wingbeats and only short glides. Smaller and shorter-winged than Black-vented Shearwater and rare Townsend’s Shearwater. Black-vented has messier brown colors on the side of its head, without distinct dark cap of Galapagos. Townsend’s is blacker above with white patches (saddlebags) at sides of rump.

识别特征

The Galápagos shearwater has dark brown upperparts, undertail and underwing flight feathers, the rest of the underparts plumage being white. It sometimes has a dark collar. Both sexes are alike, as are the young after fledging.<p>It is a slender-bodied shearwater, about 29–31 cm long, with a wingspan of around 63 cm and weighs 123-225 g. The species closely resembles the tropical shearwater, although the latter is typically blacker and has a longer tail.
