Spizella passerina
Thanks to its association with manmade habitats, the Chipping Sparrow is a familiar species. The sexes are similar but there is seasonal plumage variation. Breeding adults have a brown back with dark streaks, and buffish-brown wings with two whitish wingbars. The tail is dark and the pale gray rump is usually seen only in flight. The head pattern comprises a chestnut crown, a white supercilium, and a dark eye stripe. The throat is whitish and the underparts are otherwise pale gray. Non-breeding adults are similar, but the brown crown has a pale central stripe and the supercilium is paler buff. Juveniles are like a non-breeding adult but are heavily streaked; by their first winter, they resemble a pale non-breeding adult.
The Chipping Sparrow is present as a breeding species across most of central and northern North America, mainly from May to September. Most of the population migrates south in fall, boosting resident numbers in the south; its winter range extends to Central America. Outside the breeding season it often forms flocks. In town parks and gardens, birds are often tame.
