On 3 July 1972 an Ashy Petrel (Oceanodroma homochroa) was found incubating an egg in a rock crevice on Bird Rock, Tomales Point, Marin County, California. In addition, a petrel egg, the size, color and shape of an Ashy Petrel’s, was found cracked and deserted in a second crevice. This was donated to the California Academy of Sciences, San Francisco.
