A puffin is a type of seabird belonging to the family Alcidae. Puffins are best known for their distinctive colorful beaks, which are particularly striking during the breeding season. Their body is stocky and features a black and white plumage, adapted for life at sea. Puffins primarily feed on fish, which they catch by diving underwater. They are social birds, often nesting in colonies on cliffs or coastal islands. Puffins are also known for their ability to fly great distances and are often referred to as "clowns of the sea" due to their playful appearances and behaviors.
