The entire adult breeding population is believed to comprise 600 to 2,000 pairs, distributed among 13 breeding colonies on the island of Hispaniola (Haiti and the Domnican Republic). The black-capped petrel faces many potential threats to its continued existence, including human encroachment, deforestation, agricultural modification, offshore energy exploration and development, subsistence harvesting, predation by introduced species, pollution, mercury bioaccumulation and inadequate regulatory mechanisms. A principal foraging area appears to lie off the southeast U.S. coast, where birds may be found with relative regularity along the continental shelf or in the Gulf Stream off of North Carolina, South Carolina and Georgia. Around 90 percent of the known nesting areas are in Haiti, where deforestation continues to eat away at what little nesting habitat remains. Foraging birds are regularly found along the North American continental shelf and the Gulf Stream where nutrient-rich deep ocean waters reach the surface, which attracts favored prey items. Permits, Waterfowl The black-capped petrel is a long-winged petrel with gray to brown back and wing and white underpart. Black-capped petrels spend most of their adult life at sea, coming ashore only to breed. doi:10.1675/063.036.0213. The species has been seen year-round in the Gulf Stream. Many of these issues are inextricably linked with extremely challenging social issues, such as in Haiti where effective natural resource conservation may only occur through solving critical human health and welfare concerns. Underparts are mainly white apart from a black cap (that in some individuals extends to cover the eye) and some dark underwing markings. The Sibley Guide to Birds. These seabirds spend most of their lives in flight over open water, returning to land only to breed.

It picks food items such as squid from the ocean surface. DESCRIPTION: The black-capped petrel is a medium-sized seabird with a blackish-brown cap and collar, blackish-brown upperparts and a primarily white underside. The proposal identified areas where additional information is needed in better guide effective conservation responses. It is not known how far breeding petrels may range from nest sites during forays to provide food for chicks, nor how long they may remain away. Fish and Wildlife Service proposes Endangered Species Act protection for "little devil" Caribbean seabird | U.S. The Black-capped Petrel forages over deep waters along upwelling current edges, and is often seen in mixed-species flocks. Black-capped Petrel Working Group. The great shearwater is also superficially similar. A pelagic bird, it spends most of its time at sea, searching for food in warm waters. Intermediate birds showing features of both populations are known to exist. Predation by introduced species, such as Indian mongoose, Virginia opossum, feral cats, dogs, pigs, and rats have been noted as contributing to the decline and possible disappearance of black-capped petrels from multiple breeding locations in the West Indies.

Concentrations occur during winter, when breeding birds forage along the Gulf Stream as they migrate to and from breeding colonies. Black-capped petrel off the coast of Cape Hatteras, NC. Range and Habitat. Foraging adults may range widely, moving as far north as Maine, the Gulf of Mexico, and northern South America, though it is likely that individuals rearing young are more confined in their movements. Black-capped Petrel. Mercury concentrations in the species have been documented as seven to nine times higher than in other similar seabirds, suggesting that bioaccumulation of pollutants may pose a concern. The recent proposal by the Service to list black-capped petrel as threatened under the Endangered Species Act has heightened interest and attention. According to James Goetz, a former Cornell Lab researcher now with the Black-capped Petrel Working Group, the listing could open up new opportunities for funding conservation.
