It faces a high risk of extinction in the wild over the medium term. See full glossary

The Socotra cormorant is a black cormorant with greenish sheens, endemic to the Persian Gulf and the Arabian Sea. Despite its name it barely breeds on the island of Socotra: its main colonies are on islands in the Emirates, Bahrain and Oman. It forms feeding flocks of tens of thousands of birds, among the largest concentrations of seabirds on the planet.

Fun facts

  • Its feeding flocks are among the largest concentrations of seabirds in the world: columns of tens of thousands of birds advancing over the sea on fronts several kilometres wide in pursuit of fish shoals.
  • Despite being named after Socotra, almost its entire population breeds on islands in the Persian Gulf and off Oman, and its presence on the island it is named for is marginal.
  • Urban and port development around the Gulf has destroyed several of its historic colonies, and its population has fallen markedly over recent decades.
