Life Cycle

Least AukletThe least auklet leaves the open ocean in June to return to its breeding grounds. Least auklets gather in large colonies on boulder-covered beaches and on scattered locations on cliff faces. The female least auklet lays just one egg in a crevice. The egg hatches in about a month. The least auklet carries food for its chick back to the colony in a special throat pouch. The chick fledges in a month.


Least auklets only come on land to breed.
