Up until the latter half of the 19th century, the black-capped petrel was relatively common within its breeding range (3) (10). Around this time, a burgeoning human population in the Caribbean islands and consequential habitat loss, harvesting for food and predation by introduced mammals, saw petrel numbers crash almost to the point of extinction. Indeed, for several decades prior to the early 1960s, the species appeared to have vanished completely. Fortunately, in 1963, an estimated 2,000 breeding pairs were discovered at the existing colonies in Haiti (7). It soon became evident, however, that these populations were under the same pressures that extirpated the breeding populations on other islands. By the turn of this century, the estimated number of breeding pairs had declined to 1,000, with a total population size of approximately 5,000 birds (3). Despite increased awareness, the population in Haiti is likely to continue to decline as a result of continued conversion of broadleaf forest to cropland and pasture at Parc La Visite. Sadly, this downward population trend on the breeding grounds may be further exacerbated by proposals to develop oil and gas fields within petrel foraging grounds off the coast of the USA (2) (15).
