Common Tern
The Common Tern breeds from northern Alberta, Ontario and Newfoundland, south to the Dakotas, Great Lakes (rare) and Gulf of St. Lawrence; as well as along the Atlantic Coast south to the Carolinas. They winter in the tropics, rarely on the Gulf Cast.
Common Terns are medium-sized (14 1/2"), slender swallow-like tern with a blck cap and a deeply forked tail. Their flight is swift and graceful.
They hover ands dive for small fish.
They nest in large colonies on islands, beaches, sandbars, gravel banks, and occasionally marshes. They lay their eggs in a simple scrape on open ground.
They will vigorously attack predators and human intruders in their colonies, and may even strike with their bills!
