and desert hackberry. Avoids areas that have been heavily grazed, but may occur in suburban areas where houses are scattered and good vegetation remains.
Nest: Site is usually in low shrub or cactus, from a few inches to 7′ above ground; often in des
ert hackberry or mesquite. Nest (probably built by female only) is a deep open cup of dry weeds, grass, and small twigs, lined with fine grass and often with animal hair.
Eggs: Usually 4, sometimes 2-3. A century ago, may have typically laid clutches of 4-5 in Arizona. Eggs pale bluish white, unmarked. Incubation apparently by female only, length of incubation period not well known.
Young: Both parents feed nestlings. Young leave the nest about 8-9 days after hatching. 1 brood per year, or 2 in years with good rains.
Summer diet is mostly insects, especially caterpillars and grasshoppers, also other insects and spiders. Eats more seeds at other seasons, especially those of grasses and weeds, and winter diet may be almost entirely seeds.
Behavior: Forages mostly on the ground. Also forages up in low bushes, especially in summer
. Picks up items from ground or from stems of plants, and occasionally makes short flights to catch insects in midair. Usually forages in pairs or family groups, sometimes loosely associated with Black-throated Sparrows.
First specimens of the species were taken in 1872 in Arizona. Between 1872 and 1886, this species’ presence in Arizona declined and seemingly disappeared until 1915 before reappearing in the state.
