California Murre
30. Uria troille californica. 15 to 16 inches.
This is one of the most abundant birds breeding on the Farallones. Large numbers of their eggs are taken yearly to the San Francisco and other market places and disposed of as a food product, and as yet the birds do not seem to diminish to any great extent.
Nest.—But a single white egg is laid on the bare ledges. They vary greatly in color, from nearly white without markings to a deep greenish blue with an endless variety of patterns in light and dark brown (3.40 × 2.00).
Range.—Pacific coast, breeding from the Farallones north to Alaska.
