Fish hang out of the beak of an Atlantic puffin, on its way to feed its young chick.

Atlantic puffins spend most of their lives at sea, returning to land only to form breeding colonies during spring and summer. The Atlantic puffin’s beak appears a dull shade of grey during winter, but it changes to a bright orange when spring returns. This change earns it a nickname of “sea parrot.”
