Buller's Shearwater Ardenna bulleri

Sections

The Buller's Shearwater is a striking seabird of the Pacific Ocean. Its bright white underparts, blue-gray upperparts, and a black "M" pattern on the upperwings recall a Pterodroma petrel, from which it is easily distinguished by shape and behavior. It breeds on islands off the North Island of New Zealand, dispersing through much of the tropical and subtropical Pacific Ocean when not breeding. In the Neotropics it occurs along the Pacific coast of Central America south off northern South America to the Humboldt Current off Peru and northern Chile. This species feeds on fish, squid, and crustaceans, perhaps foraging more at night than other shearwaters. It associates with other seabirds and sometimes follows trawlers. It breeds colonially in burrows or crevices on forested slopes or cliffs.
