The golden-crowned sparrow (Zonotrichia atricapilla) is a large New World sparrow in the Passerellidae family, found in the western part of North America. It is a migratory species, breeding from north-central Alaska (including the Aleutian Islands as far west as Unimak Island) and central Yukon south to the northwestern corner of the US state of Washington, and wintering from southern coastal Alaska to northern Baja California.
In the winter, it is generally found in brushy areas, (particularly chaparral), usually in dense shrubs.
Like other Zonotrichia sparrows, the golden-crowned sparrow feeds on the ground, where it forages by pecking and scratching. It also occasionally leaps into the air after insects or gleans them from foliage. Its diet, particularly in the winter, consists primarily of plant material; items include seeds, berries, flowers and buds, as well as the occasional crawling insect. The species is an important destroyer of weed seeds on the Pacific Slope, with various ryegrasses, fescues, bromes, pigweeds, chickweeds, mulleins, filarees, common knotweed and poison oak among its known food sources.
