Gould, P. J. 1964 Sooty Storm Petrel 1 February 11--Pacific Ocean, Grid Area SW Johnston Island One bird seen at 0915 by Jim Ludwig definitely did not have a white rump. It was all black. He did not see any light bars on the wings. The bird came within 50 yds of the ship in good light. It flew like a Harcourt's Storm Petrel and was about the same size, perhaps a trifle larger.
