Black Tern

Horicon Marsh, Wildlife Refuge, Horicon Wisconsin

The black tern (Chlidonias niger or Chlidonias nigra) is a small tern generally found in or near inland water in Europe and North America. As its name suggests, it has predominantly dark plumage.
Adults are 25 cm (9.8 in) long, with a wingspan 61 cm (24 in), and weigh 62 g (2.2 oz). They have short dark legs and a short, weak-looking black bill, measuring 27 mm (1.1 in), nearly as long as the head. The bill is long, slender, and looks slightly decurved. They have a dark grey back, with a white forewing, black head, neck (occasionally suffused with grey in the adult) and belly, black or blackish-brown cap (which unites in color with the ear coverts, forming an almost complete hood), and a light brownish-grey, 'square' tail. The face is white.
