BLACK-CHINNED SPARROW.

565. Spizella atrogularis. 5½ inches.

This is easily identified by the black chin, throat and forehead. It is quite common in parts of southern California, and south into Arizona and New Mexico. The habits are similar to those of the Field Sparrow, their eggs differing in being unspotted and are a bluish green (.65 × .50).
