Overview

Legs black. Nonbreeding plumage shows dark cheek patch. Found in marshier habitats than most other terns, in the Americas usually near the coast but not on the ocean (though also occasionally seen on beaches and mudflats); in Europe and Asia can also be found in wetlands well away from the coast.

Behavior
