- Puffinus subalaris
Identification
The Galápagos shearwater has dark brown upperparts, undertail and partial underwing. The rest of the underparts is white. Sometimes, the underparts have also a dark colour. Both sexes and juvenile after fledging are alike.
It's a slender-bodied shearwater, about 29 to 31 cm in length and a wingspan of 63 cm. 123 to 225 g in weight.
Distribution
It is an endemic breeder of the Galápagos Islands, and is largely sedentary, although individuals are commonly seen as far as the Oaxacan coast of Mexico.
Taxonomy
Until recently it was considered to be a subspecies of Audubon's Shearwater, but it is actually one of two members of a very ancient lineage of the small Puffinus species, the other being, as indicated by mtDNA cytochrome b sequence data, the Christmas Shearwater (Austin et al., 2004).
Habitat
Open ocean and breeding on Galápagos islands.
Behaviour
The Galápagos shearwater is a gregarious species and will feed at sea with other shearwaters and boobies. It flies low over the water and feeds on squid, fish and offal.
