. "EN" . "The Bermuda petrel (Pterodroma cahow) is a gadfly petrel. Commonly known in Bermuda as the cahow, a name derived from its eerie cries, this nocturnal ground-nesting seabird is the national bird of Bermuda, and a symbol of hope for nature conservation. For 330 years, it was thought to be extinct.The dramatic rediscovery in 1951 of eighteen nesting pairs made this a \"Lazarus species\", that is, a species found to be alive after having been considered extinct."@en . . . . .
