Cassin’s auklet

Cassin's auklet (Ptychoramphus aleuticus) is a very small, chubby seabird belonging to the auklet family (Alcidae). These birds are commonly found along the Pacific coast of North America, ranging from the Aleutian Islands to Baja California.12

Auklets are known for their breeding plumage, which often includes head ornaments and brightly colored bill plates, similar to puffins. Cassin's auklet is described as the plainest and grayest species within this family. They typically nest in crevices near the sea and lay a single egg, with the young remaining in the nest until they are fully fledged.2
