CALAVERAS WARBLER.

645a. Vermivora rubricapilla gutturalis. 4½ inches.

Found in the Pacific coast regions, breeding from central California north to British Columbia. Winters south to Mexico. In Oregon and California, these birds are quite common in favorable localities on the mountain sides. They build their nest on the ground in a slight depression, making it of twigs and grasses, and usually well concealed with overhanging grass or brush. Their four eggs are a creamy white, with fine spots of brown and lavender, forming a wreath about the larger end (.60 × .45).
