Song:
Song consists of a number of short whistled notes
followed by longer whistles: sweet-sweet chew-chew seet chew.
Distribution:
Breeds
from southern British Columbia, east to southern Saskatchewan and sections of
midwestern U.S., and south to southeastern California, northwestern Baja California,
southern Nevada, southwestern Utah, central Arizona, northern New Mexico, and
western Oklahoma. Winters from southern Arizona (scarce), south to portions
of Mexico.
Habitat:
Found in arid, brushy areas in canyons,
riparian thickets, chaparral and open woodlands. During
migration
and in winter, found in
open, grassy and weedy areas. Results of Idaho study conducted in cottonwood
forest found bunting most strongly associated with dense shrub layers, a willow
subcanopy, and herbaceous
ground cover; species
also avoided grazed areas.
Diet:
Species feeds on insects (grasshoppers,
caterpillars, beetles, ants, etc.), and seeds (wild oats, canary grass, needlegrass,
etc.).
Ecology:
Nests in shrub. After breeding, may form
flocks and move to higher elevations.
Reproduction:
Breeding begins late March in southern
range, early June in north. Female incubates 3-5 eggs for 12 days.
Nestlings are altricial
and downy, are either
tended by both parents or by female, and leave nest in 10-15 days.
