Petrel, Ashy bird picturesASHY PETREL
108. Oceanodroma homochroa. 7 inches.
This species breeds most abundantly on the Farallone Islands, sooty gray in color, their plumage matching their surroundings so closely that, unless one is looking for them, they will easily be overlooked.
They sit very close when nesting, and will even allow themselves to be removed from the nest by hand, so tame are they.
They build in burrows or in any crevice of the rocks, laying their single white egg on the ground or rock without much, if any, lining to the nest.
