Roseate tern  (Sterna dougallii)

The roseate tern was first identified in 1812 by Dr MacDougall of Glasgow, hence the specific name dougallii (2). Males and females are similar in appearance; during the breeding season they have a black forehead, crown and nape (2) and pale plumage with a rosy tinge to the breast, (3) which gives the species its common name (4). The grey tail is deeply forked with white long outer feathers called 'streamers' (3). In winter the forehead becomes white (3). A particularly vocal species on the breeding grounds, calls of the roseate tern include a 'chew-ik' and a 'kraak' when alarmed (2).
