binomial_authority = (Nichols & Mowbray, 1916) The Bermuda Petrel, "Pterodroma cahow", is a gadflypetrel .Commonly known in
Bermuda as the Cahow, a name derived from its eerie cries, thisnocturnal ground-nestingseabird is the national bird of Bermuda, and a symbol of hope fornature conservation. It was thoughtextinct for 330 years. Its dramatic rediscovery as a "Lazarus species", that is, a species found to be alive after being considered extinct for centuries, has inspired documentaryfilmmakers .Initially superabundant throughout the
archipelago , the Cahow is a slow breeder, but excellent flier, and spends itsadult life on the opensea s. At five years old it returns to its former nesting place and begins breeding, laying only one egg per season. Cahows mate for life.The Cahows' eerie
nocturnal cries stopped the early Spanish seafarers settling the Islands out of superstition, as they thought the Isles were inhabited by Devils. Instead they put ashore hogs as a living foodstore for passing ships, and so began the onslaught on the Cahow's existence. Following Bermuda's colonisation by the English, introduced species likerats ,cats anddogs , and mass killings of thebirds by early colonists decimated numbers. Despite being protected by one of the world's earliest conservation decrees, the Governor's proclamation "against the spoyle and havocke of the Cohowes," the birds were thought to have been driven toextinction since the 1620s.In
1951 , 18 surviving nesting pairs were found on rockyislets in Castle Harbour, and a program was set up byDavid B. Wingate to build concreteburrow s and wooden bafflers for the nestingtunnel s in order to keep out the slightly larger, competing 'Bermuda longtail', and to restore the nearby Nonsuch Island to be a future viable base for thespecies .Enjoying legal protection, the species has started to make a good recovery, The main threat for the future is lack of suitable breeding habitat.
Hurricane Fabian destroyed many nesting burrows in2003 , and recently the larger and ecologically-restored Nonsuch Island is being repopulated with chicks, their translocation timed so they will imprint on these surroundings.

Nonetheless, the global population of this bird in2005 was only about 250 individuals.References
