Sterna forsteri (Forster's Tern)

Language: French; Spanish

Wikipedia Abstract

The Forster's tern (Sterna forsteri) is a member of the tern family, Sternidae. The genus name Sterna is derived from Old English "stearn", "tern", and forsteri commemorates the naturalist Johann Reinhold Forster. It breeds inland in North America and winters south to the Caribbean and northern Central America. This species is rare but annual in western Europe, and has wintered in Ireland and Great Britain on a number of occasions. No European tern winters so far north.
