Razorbills are seabirds belonging to the family Alcidae, which also includes puffins and guillemots. They are characterized by their black and white plumage, a stout body, and a distinctive, thick bill with a sharp edge. Razorbills primarily inhabit rocky coastal areas in the North Atlantic and are known for their excellent diving abilities, often reaching depths of up to 120 meters in search of fish. These birds typically breed in large colonies on cliffs and rocky shores, laying a single egg each year. During the breeding season, they engage in elaborate courtship displays. Razorbills feed mainly on small fish, such as sandeels and herring, and are often seen diving in pursuit of their prey.
