A puffin is a seabird known for its colorful beak and distinctive appearance. These birds are part of the family Alcidae and are commonly found in the North Atlantic Ocean. Puffins are excellent swimmers and divers, using their wings to propel themselves underwater while hunting for fish. Puffins primarily feed on small fish, such as sandeels and herring. They nest in colonies on coastal cliffs and islands, where they create burrows for their eggs. Puffins are social birds, often seen interacting with one another, and they are known for their charming, clumsy flight.
