Gull-Billed Tern (Paperback)

High Quality Content by WIKIPEDIA articles! The Gull- billed Tern, Gelochelidon nilotica, formerly Sterna nilotica (Bridge et al., 2005), is a seabird of the tern family Sternidae. It is now considered to be in its own genus. It breeds in warmer parts of the world in southern Europe (and a very small isolated population in northern Germany and Denmark), temperate and eastern Asia, both coasts of North America, eastern South America and Australia. This bird has a number of geographical races, differing mainly in size and minor plumage details. All forms show a post-breeding dispersal, but the northern breeders are most migratory, wintering south to Africa, the Caribbean and northern South America, southern Asia and New Zealand.
