About the Black Tern
The black tern (Chlidonias niger) is a small tern generally found in or near inland water that breeds in Europe, Western Asia and North America. In winter the birds migrate to coastal areas of Africa and South America. The black tern was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Sterna nigra. Linnaeus specified the type location as Europe but it is now restricted to Uppsala in Sweden. The black tern is now one of four species placed in the genus Chlidonias that was introduced in 1822 by the French naturalist Constantine Rafinesque. The genus name is from Ancient Greek khelidonios, "swallow-like", from khelidon, "swallow": another old English name for the black tern is "carr (i.e. lake) swallow". The species name is from Latin niger "shining black". As its name suggests, it has predominantly dark plumage. In some lights it can appear blue in the breeding season, hence the old English name "blue darr".
Two subspecies are recognised. These are listed below with their breeding ranges. Adults are 25 cm (10 in) long, with a wingspan 61 cm (24 in), and weigh 62... Wikipedia →
