Bird lovers will like to read black Tern facts.

Terns are a common group of birds that are seen all over the world. One of the most striking species among this family of birds has to be the black tern (Chlidonias niger).

Just by the bird's name, you already know that this species is covered with black or dark-gray plumage. These birds can be easily spotted in North America, Asia, and the coastal areas of Africa and South America.

In North America, the New York and Hawaii black tern population has been quite constant. During the winter months, the black tern makes the journey of migration to warmer places.

It is one of the many bird species that like to eat insects and small fish. These birds build nests and live in areas of thick vegetation such as in marshes and bogs.

Freshwater marshes form the favorite breeding grounds of this species. However, in South America and Africa, these birds may choose to live near marine or coastal environments.

The colonies formed by these birds can have hundreds or even thousands of individuals. The population of North American black terns has faced problems because of habitat loss, but conservation is underway.
