The Least Auklet (Aethia pusilla) is a small seabird belonging to the alcid family. A family that includes the puffins, murres, and murrelets. Least Auklets usually live in huge colonies (often up to a million birds!). They are highly social and very noisy. Listen to the sound of a Least Auklet colony.
Least Auklets lay their single egg in a rocky crevice, and both parents share the incubation and chick-feeding duties. Least auklets eat zooplankton, and parents bring these small prey back to their chick in a pouch in their throat (gular pouch).
