Learn more about our Gulf Stream signature species and why it is possible this could actually be two or more cryptic species! Black-capped Petrels, or Diablotins, are present in the Gulf Stream off of Cape Hatteras year round. These gadfly petrels nest on Hispaniola in the mountains between the Dominican Republic and Haiti. It is likely there are other nesting sites in the Caribbean, like Dominica, but an actual nesting burrow away from Hispaniola has yet to be discovered. They occur in a number or variations and have most recently been treated as two or more species by Howell and Zufelt in their Oceanic Birds of the World photo guide. We still just use the terms white-faced and dark-faced Black-caps to differentiate the two extremes of the spectrum. There are a number of birds showing intermediate traits.

Black-capped Petrels were recently added to the Endangered Species Listing here in the United States in January of 2024. Hopefully this will lead to more protection and conservation in the places they nest and also protect their critical habitat here east of us on Cape Hatteras at the western edge of the Gulf Stream. This of course means bringing them in to conversations about wind energy development offshore of the continental shelf to the east of the mid-Atlantic states!

Currently there are a number of projects working with Black-capped Petrels offshore of Hatteras and in the Caribbean. Please find links below to blog posts about Black-capped Petrels plus projects that concern them!
