The Forster's Tern is a medium-sized bird belonging to the family Laridae, which includes gulls and terns. It is characterized by its slender body, long wings, and a distinctive black cap on its head during the breeding season. The bird's plumage is mostly white with a grayish back, and it has a sharp, pointed bill that is ideal for catching fish. Forster's Terns are commonly found near freshwater and coastal habitats across North America. They are known for their graceful flight and diving skills, often seen hovering above the water before plunging to catch small fish. These terns typically nest in colonies, using marshy areas or sandy islands for breeding.
