Species at Risk Around Akwesasne

Black Tern - Chlidonias niger

Black terns are migratory birds that can be found along most waterways around Akwesasne from late spring to early fall. It is considered to be a species that is of special concern in Canada as much of the habitat it requires for nesting is being diminished. The tern is about 10 inches in length and is dark colored on the top half with white underside and almost resembles a small gull. Black terns migrate to South America for the winter months and make the trip up north in the spring time for breeding.

Black tern calls are high pitched shrills which can be heard as they fly over an area. The common tern, Sterna hirundo is another type of tern in the area but is white with an orange beak. Both birds are similar in size, shape, behavior and calls.

The habitat Black terns prefer are wetlands that contain floating mats of vegetation which they need to construct nest on. The nests are usually found on mats of cattails and are usually at water level and sometimes 12 inches above water level. The Black tern feeds on insects, mollusks, crayfish and small fish. The birds can be seen flying and diving for food along the water surface. Akwesasne has one of the largest breeding colonies in the east due to the abundant wetlands in the area and a rich food source available.
