Common Tern Migration

Summer Range: Common Terns arrive on northern breeding grounds from late April through mid-May; many adults are already paired when they arrive. The birds breed from Alberta and Northwest Territories of Canada southward to Montana, and eastward through the Great Lakes region to Newfoundland and New Jersey, and southward along Atlantic Coast to South Carolina and Louisiana. Breeding colonies are called terneries.

Winter Range: Common Terns typically migrate in small flocks in mid- to late October, spending winter along both ocean coasts from the southern United States to southern South America.
