Feeding Behavior

Forages mostly while hopping on the ground, occasionally up in shrubs. Except when nesting, usually forages in flocks, sometimes mixed with other sparrows.

Eggs

3-5, usually 4. Pale blue-green, with dark brown spots usually concentrated at larger end. Incubation is mostly by female, about 10-14 days. Young: Both parents feed the nestlings. Young leave the nest about 7-9 days after hatching, jumping to ground and then scrambling into cover; unable to fly for about another week. 1 brood per year, sometimes 2.

Diet

Mostly seeds and insects. Diet is not known in detail, but feeds mostly on seeds at most times of year, especially those of weeds and grasses; also some leaf buds, catkins, berries. Also eats many insects, especially in summer, including caterpillars, grasshoppers, true bugs, ants, damselflies, and many others, as well as spiders. Young are fed mostly insects.

Nesting

Males sing in spring to establish and defend nesting territories. During the breeding season, adults often forage away from nesting area, unlike most songbirds which do all their foraging within the breeding territory. Nest site is usually very low, either on ground or in low shrubs, up to 5' high. In some areas, nests built early in season placed on ground, later ones higher. Local populations often specialize in nest sites; in one Manitoba study, almost all nests built in snowberry bushes; other common sites include rosebushes and clumps of grass. Nest (built by female) is open cup of grass, weeds, twigs, rootlets, lined with fine grass, rootlets, animal hair.
