BLACK PETREL.

107. Oceanodroma melania. 7½ inches.

These birds are sooty black all over, lacking the white rump of the two or three preceding. All of the Petrels have a very offensive musky odor, which is always noticeable about an island inhabited by them. The skins and eggs of the birds always retain this odor.

Nest.—Made in burrows similar to the others, but sometimes containing a small amount of nesting material; grass and roots.

Range.—Southern California southward to Mexico.
