Distinguishing features
It is an all-black to sooty brown storm petrel with a plumbeous gloss on its head, neck and mantle in fresh plumage. Its ventral area, caudad from the neck, and wing lining are blackish brown, and become almost fuscous with wear of the plumage. External edges of wing coverts in the bird become whitish with wear, but are normally brown; the whitening produces a broad grayish bar that generally extends closer to the wing's bend than what Robert Cushman Murphy observed as a somewhat similar mark in the black petrel Oceanodroma melania. Its iris is brown, and its bill and feet are black with a deeply forked tail. (Wikipedia)
