These birds have brown backs streaked with black, and distinctive head markings. Their cup nests, built by the female, are of plant material lined with fine grasses and constructed on the ground, low in a tree or bush, or in a niche in a wall.

The female lays brown-blotched greenish-blue or greenish white eggs, which she incubates for 12–14 days. The male helps in feeding the chicks.

Zonotrichia sparrows feed on the ground on seeds, fallen grain, insects and spiders.
