The Socotra Cormorant, Phalacrocorax nigrogularis, is a threatened species of cormorant that is endemic to the Persian Gulf and the south-east coast of the Arabian Peninsula. It is also sometimes known as the Socotran Cormorant or, more rarely, as the Socotra Shag. Individuals occasionally migrate as far west as the Red Sea coast. Despite its name, it was only confirmed in 2005 that it breeds on Socotra.
