About These Birds
Least Auklet
Least Auklet, 15–16 cm, is the smallest auk, breeding in immense colonies (millions) on rocky Aleutian and Bering Sea islands. Dark above, streaked white below; a tiny white plume above the eye. Planktivore; sieves copepods and euphausiids at sea. Makes loud buzzing display choruses at colony.
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.
