Saturday (8-13), a Santa Clara Adubon Society pelagic trip to the
Farallones led by David Wimpfheimer, Bob Power and myself found a
probable HAWAIIAN PETREL several miles south-southwest of South
Farallon Island. The bird was an obvious Pterodroma (angled wings,
high-arching flight) with little or no contrast on its brownish-gray
dorsal, a pronounced black margin on the ventral surface of the
wings, and an interesting black strip that led away from the wrist
toward the hip of the bird. No markings on the flank were evident.
The tail was longish and tapered to a point, and the cap was strongly
dark, and sharply demarkated from the white face and forehead.
The location was:
8.67 miles SSW of Farallon Islands
N 37 degrees 36.87 minutes
W 123 degrees 04.36 minutes
Images of the bird, which was found shortly after midday in a large
flock of Shearwaters, can be found on Dave Kutilek's blog: http://
