Sea swallow is a colloquial term used to describe a type of bird known scientifically as Sterna hirundo, or the common tern. It belongs to the family Laridae, which includes other species of terns. The sea swallow is characterized by its slender body, long, pointed wings, and forked tail. It has a white underbelly and a bluish-gray upper body, with black caps on its head during the breeding season. These elegant birds are primarily found near coastlines, estuaries, and the open ocean, where they can be seen swooping and diving into the water to catch small fish.
The name "sea swallow" is derived from their graceful flight and aerial hunting behavior, resemblant of swallows. Their ability to hover and plunge into the water with great agility resembles the way swallows dart through the air. Additionally, the sea swallow's diet primarily consists of small fish, making it even more reminiscent of these aerial insectivores.
Sea swallows are known for their extensive migratory patterns, traveling from their breeding grounds in the northern hemisphere to warmer regions during the winter months. They nest in colonies on coastal beaches or islands, often in large numbers. These birds are highly vocal, emitting high-pitched calls to communicate with their mates or alert others of potential threats. The sea swallow is a symbol of freedom and adaptability, mesmerizing observers with its elegant flight and gentle presence along the shorelines.
The common tern; the stormy-petrel.
