The Least Tern is a small species of tern that lives in the Americas. Most breed in parts of North America; they are migratory and spend the winter in southern North America, Central America, and northern South America.
Least Terns eat a diet of mostly fish. They hunt by hovering on the wing until prey is found. They plunge into the water to capture prey items.
The population trend for the Least Tern is decreasing, but because of its widespread range the conservation status is Least Concern as of June 2013. In the United States, the Least Tern is listed as threatened or otherwise a species of concern in most states, primarily due to loss of breeding habitat.
