Atlantic puffin

Puffins sometimes form large colonies on the grassy tops of oceanic islands. These birds winter at sea without returning to land. In subarctic regions, puffins occupy an ecological niche similar to that taken in Antarctica by penguins. They dwell in cold seas, feeding on fish, using their short wings for propulsion. Unlike penguins, puffins are capable of flight, although they are not particularly skilled fliers.
