About These Birds
Tufted Puffin
Tufted Puffin, 36–41 cm, is the largest North Pacific puffin, breeding on grassy slopes of islands from California to Kamchatka. Jet-black body, white face, massive orange-red bill, striking golden head tufts. Piscivore; carries multiple fish crosswise in bill. Pelagic in winter across North Pacific.
Cassin's Auklet
Cassin's Auklet, 21–23 cm, is a small, almost entirely dark grey auklet breeding in burrows on rocky North Pacific islands from Baja California to the Aleutians. Feeds almost exclusively on zooplankton — euphausiids and copepods — at night. Highly colonial; winters near shore.
