Extinct.\u00a0 Formerly bred on St. Helena in the South Atlantic.<\/strong><\/p>

The cause of extinction is not known, but the apparent swiftness of its decline and the correlation to settlement of the island tend to indicate either rats or the cats introduced to control them as the presumptive cause.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Identification<\/strong><\/span><\/p>

A mid-sized gadfly petrel whose closest relatives, as determined through genetic analysis, are the Cape Verde<\/strong><\/a> and Desertas Petrels<\/strong><\/a>.\u00a0 There appears to be no surviving evidence to provide details of its appearance.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
