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. It was thought extinct for 330 years. Recently, the Cahow's touch-and-go existence has inspired documentary filmmakers. A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the human (diurnal) schedule. ...

Initially superabundant throughout the archipelago, the Cahow is a slow breeder, but excellent flier, and spends its adult life on the open seas. At five years old it returns to its former nesting place and begins breeding, laying only one egg per season. Cahows mate for life. An archipelago is a landform which consists of a chain or cluster of islands. ...

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 British, introduced species like rats, cats and dogs, and mass killings of the birds 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 to extinction since the 1620s.

In 1951, 18 surviving nesting pairs were found on rocky islets in Castle Harbour, and a program was set up by David B. Wingate to build concrete burrows and wooden bafflers for the nesting tunnels 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 the species. 1951 (MCMLI) was a common year starting on Monday; see its calendar. ... Castle Harbour is a large natural harbour in Bermuda. ... Dr David Balcombe Wingate OBE, is an ornithologist, naturalist and conservationist. ... Binomial name Phaethon lepturus Daudin, 1802 The White-tailed Tropicbird Phaethon lepturus, is a tropicbird, smallest of three closely related seabirds of the tropical oceans. ... Nonsuch Island (originally Nonesuch Island) is part of the chain which makes up Bermuda. ...

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 in 2003, and recently the larger and ecologically-restored Nonsuch Island is being repopulated with chicks, their translocation timed so they will imprint on these surroundings. This work is being undertaken by the present Bermuda Conservation Officer Jeremy Madeiros assisted by the Australian petrel-specialist Nick Carlile.
