Sometimes also called the Sea Swallow, the Common Tern is 34–37cm long with a 70–80cm wingspan. It breeds in temperate and sub-Arctic regions of Europe, Asia and east and central North America. A strong migrator, the Common Tern winters south in coastal tropical and subtropical regions, including the north and east coasts of Australia.
Breeding occurs in colonies on coasts and islands and often inland on suitable freshwater lakes. When breeding the Common Tern is white with a black crown. When not breeding, the forehead is white. Common Tern's can be quite defensive of their nest and young, see the following clip for a demonstration: http://www.youtube.com/watch?v=9rbDg6C2YIw
Sterna hirundo are known to reach an age of 23 years. They feed by plunge-diving for fish, from either the sea or freshwater lakes and large rivers. The offering of fish by the male to the female is part of the courtship display.
The call of the Common Tern is a clear piping.
