Cahows (Pterodroma cahow), also called the Bermuda petrel, are the national bird of Bermuda. There are only 300 cahow birds left on Bermuda, and they breed nowhere else in the world.Fox News: Bermuda says rare national bird born on reserve (April 17, 2009)
Efforts to reestablish a colony on in a protected reserve on Nonsuch Island in Bermuda have been ongoing since 2004, with fledgling birds purposefully moved on to the island. In April 2009, scientists reported that they had found the very first fledging born on Nonsuch Island, believed to represent a step in the recovery of the species.Fox News: Bermuda says rare national bird born on reserve (April 17, 2009)
Reviving the Cahow
The cahow is a seafaring bird, returning only to land to mate and raise chicks. Once abundant, they nearly died out after the introduction of pigs, dogs, cats and rats to Bermuda in the 16th and 17th century.Ocean Wanderers: Bermuda Petrel (Pterodroma cahow)The species was rediscovered in 1951, when 18 nesting pairs were discovered.Ocean Wanderers: Bermuda Petrel (Pterodroma cahow) Renowned conservationist David Wingate became involved in the Cahow Recovery Programme and a special facility was built for the birds on Nonsuch Island, with 100 artificial concrete burrows.IUC Redlist: Pterodroma cahow
Between 2004 and 2005, a total of 105 cahow chicks were moved to Nonsuch Island and fitted with tags. Of those, 102 successfully fledged from the island and flew to sea. In April, 2009, the first fledgling born on Nonsuch Island was discovered.Bermuda Sun: First cahow chick on Nonsuch since 1620 (April 17, 2009)
