A more southern species; occurs occasionally on the lower California coast and islands.
Dark-bodied Shearwater
95. Puffinus griseus. 17 inches.
This is a southern species which, after nesting on the islands in the far south during our winter months, comes north and appears off the Pacific coast of the United States during our summer months, as far north as Alaska. They are a dark sooty gray, except for the under-coverts, which are whitish.
Nest.—Habits are the same as the others of the family. The single white egg is laid at the end of the burrows or in crevices under rocks (2.40 × 1.65).
