buřňák růžovonohý Ardenna creatopus

Large shearwater, often messy-looking with smudgy brown neck and underwings. Underparts are usually fairly clean white, but sometimes mottled brownish or rarely all-dark. Look for pink bill with dark tip; namesake pink feet are hard to see. Relatively slow, lazy wingbeats compared with other shearwaters, with high arcs in strong wind. Common and widespread in the eastern Pacific, from Alaska to Chile. Occasionally seen from land, but prefers to stay offshore. Often gathers in large flocks, freely mixing with other species of shearwater.
