El Diablotin, also known as the Black-capped Petrel is a real crowd pleaser. It brings the effortless flight of Petrels and Shearwaters and takes it to another level. These birds fly hundreds of miles sometimes without having to flap their wings only to get a snack. They are super fast and graceful and can be seen harassing jaegers so they are pretty badass. One of the best places to see them is out in the Gulf Stream off the coast of North Carolina. Even if you dip on everything but a Black-capped on a pelagic, it is still a good trip.
This one was especially dark.
