They like open fields with brushy edges. They enjoy the protection of brambles and shrubs or trees, but will nest on the ground in tall grasses.
Females build the nests out of twigs, coarse grasses, pine needles, moss, bark, and dead leaves. They line the nest cup with fine grasses and hairs. Incubation is 10 to 14 days, and fledging is in 8 to 10 days. The clutch size is 3 to 7 eggs, that are greenish, greenish-blue, or bluish speckled with reddish brown and heavier on the large end.
They eat mostly seeds from weeds, grasses, and grains from oats, wheat, barley and corn, and do consume large numbers of insects, like caterpillars, and beetles. Also fruits like blackberries.
