Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment.

The birds formerly bred on Ascension Island itself, but the colonies were exterminated by feral cats introduced in 1815. The birds continued to breed on a rocky outcrop just off the shore of the island. A program conducted between 2002 and 2004 eradicated the feral cats [67] and a few birds have returned to nest on the island. [68] [69]
