September 8th, 2007. Monterey Bay, CA.
Ashy Storm-petrel Oceanodroma homochroa. (c.1,500).

Impressive rafts of these with some Black Storm-petrels seen on a 'Shearwater Journeys' dedicated pelagic.

Images taken through Canon Powershot A540 using Leica 8 x 42 binoculars.

This may be a molting bird showing a tail shape closer to Least Storm-petrel than Ashy.
