Spotted
A North American tern often found in freshwater or brackish marshes, the Forster's Tern is characterized by its relatively long legs and a shaggy black cap in breeding plumage. It possesses a bright orange bill with a black tip.
Where to spot
Primarily found in North America, breeding in freshwater marshes and along coasts. They winter along the coasts of North and Central America.
How to spot
Look for its orange bill with a black tip, long legs, and white primary feathers that are visible from below in flight. They are often less vocal than Common Terns. The slightly shaggier black cap in breeding plumage is also a good clue.
When to spot
Best observed during their breeding season from spring to summer within their North American range. They are migratory, so they can also be seen during migration periods or in their wintering grounds.

Unlike many terns that prefer saltwater coasts, Forster's Terns frequently breed in freshwater marshes, building floating nests made of vegetation.
