At a Glance

This Eurasian species, rare in our area, is similar to Black Tern and usually associates with it. Most often seen with flocks of migrant Black Terns on the Atlantic Coast in late summer. It has also strayed from Asia to Alaska. There are a couple of instances of adults summering around marshes in the interior, and an adult once paired with a Black Tern in Quebec and nested there.
