Aleutian Tern in Detail.

Aleutian Tern (Onychoprion aleuticus) are a small sea bird mostly gray in color with a black-capped head and black strap that extends from their cap across their eyes to the rear of their black beaks. They have long pointed dark gray tails, which extend out from a white rump and black legs. When feeding the terns plunge and dive for fish.


Aleutian Terns nest on the ground laying 2-3 eggs. Conflicts of land with livestock grazing on Kodiak Island sometimes turn problematic for the terns.

Habitat & Range

The Aleutian Tern can be found on Kodiak Island and Afognak Island where populations are declining.

Aleutian Terns winter in the South Pacific around Indonesia and Malaysia
