The Crested Auklet is a seabird and a member of the Auk family, meaning they are related to species like the Razorbill, Atlantic Puffin, Xantus's Murrelet, and the extinct Great Auk.
Both male and female Crested Auklets sport a crest of bristle feathers on the top of their heads. The size of the crest varies between individuals.
Crested Auklets are also known for a peculiar citrus-like odor they develop during breeding season.
Crested Auklets eat plankton and fish larvae. They feed by diving under the water in search of their tiny prey.
