Gull-billed tern
The gull-billed tern (Gelochelidon nilotica), formerly Sterna nilotica, is a seabird of the tern family, Sternidae. It is now considered to be in its own genus. The genus name is from Ancient Greek gelao, "to laugh", and khelidon, " swallow". The specific '' niloticus'' is from Latin and means of the Nile.
