DARK-BODIED SHEARWATER. 
95. Puffinus griseus. 3 7 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 x 1.65). 
SLENDER-BILLED SHEARWATER. 
96. Puffinus tenuirostris. 14 inches. 
This is much smaller than the preceding, otherwise resem¬ 
bling it in color and markings, being a little lighter under the 
throat, and the bill more slender in proportion to the size of 
the bird. Bill and feet nearly black, as is also the one above. 
Nest. —Nesting habits and range of the bird are the same as 
the Dark-bodied Shearwater; it is not found on the N. A. 
coast as commonly as the other.
