Bermuda Petrel
From Biocrawler, the free encyclopedia.
Commonly known in Bermuda as the cahow, this seabird nests in burrows in the rocky outlying islands that remian free of cats and rats. Initially common throughout the islands, introduced species and mass killings of the birds by early colonists decimated numbers. This was mainly due to the low number of chicks being raised, and the easy harvesting of the birds by men, especially at night. Believed to have been driven to extinction, a few were sighted on nonsuch island, and a program has been set up to build concrete burrows for the nesting sites in order to help facilitate breeding.
