PACIFIC LOON.

10. Gavia pacifica. 30 to 32 inches.

This species differs from the [Loon] in having the crown gray, and white streaks down the back of the neck, and in the color reflections of the black on the head. It is a trifle smaller also.

Nest.—Similar to the former, the eggs being more of a greenish brown, with the black spots mostly on the larger end (3.10 × 2).

Range.—Western N. A., breeding in Alaska and British Columbia; winters along the Pacific coast to Mexico.
