Chipping Sparrow (Spizella passerina) 5.5 inches
Seen in northern parts of the country only during the breeding season, some Chipping Sparrows are year-round residents of southern Arizona. Their numbers are probably augmented by migrants during the winter. Adults have streaked brown wings and back with an unstreaked gray breast and belly. A dark line through the eye sets off a crown which is rusty-colored April through August and streaked brown during the non-breeding season.
Chipping Sparrows are ground foragers feeding on insects, spiders, and seeds. They form small flocks and may join mixed-species groups in the winter. In winter Chipping Sparrows may be confused with Brewer's Sparrows that winter in southern Arizona, Texas, and Mexico; the facial pattern is the main distinguishing feature to look for, with the brown crown and black eyestripe marking the Chipping Sparrow.
