Black-capped Petrel Working Group
The Black-capped Petrel (Pterodroma hasitata), also known as the Diablotin, is one of the Caribbean’s most fascinating seabirds, and one of its most threatened. Spending most of its life at sea, this species comes to land only to breed, nesting in burrows or crevices which they visit only in cover of darkness. Almost wiped out by overhunting, the species only persists in remote mountain areas of a few Caribbean nations.
It is perhaps unsurprising that this bird has long been enigmatic and poorly-understood. Even the basics of its range and life history remained shrouded in mystery: where do they nest? how many are there? what threatens their survival now?
Recently, through the pioneering use of new techniques like radar observation and old-fashioned field work, great strides have been made in understanding this bird. Nesting sites have been located on Hispaniola and individual nests have been located and studied. On the island of Dominica, a breeding population was confirmed for the first time in over 150 years. And the Black-capped Petrel was recently featured in ZiNG Magazine, LIAT Airlines in-flight magazine.
It is a truly fascinating time to study the Black-capped Petrel. This Working Group is currently using multiple methods to learn more about the nesting sites and nesting behavior of this species. This information will be used to guide conservation plans and help ensure the survival of this remarkable seabird.
