Black Terns (Chlidonias niger) wheat field Romania_w_1664

            The Black Tern is very social. It breeds in loose colonies and usually forages, roosts, and migrates in flocks of a few to more than 100 birds, occasionally up to tens of thousands.
An outlier in a world of white seabirds, breeding Black Terns are a handsome mix of charcoal-grey and jet black. Their delicate form and neatly pointed wings provide tremendous agility as these birds flutter and swoop to pluck fish from the water’s surface or veer to catch flying insects, much as a swallow does. Black Terns nest in large freshwater marshes, in small, loose colonies. They winter in flocks along tropical coastlines. In the last half-century, this species has lost about half its North American population.
The oldest recorded Black Tern was at least 11 years, 3 months old. It had been ringed in Wisconsin and was later found in Louisiana.
