Food Comments
Forages on the ground; eats insects, seeds, and waste grain.
Reproduction Comments
Breeding begins mid- to late May (Harrison 1978). Clutch size is 3-7 (usually 4-5). Incubation lasts 12 days (Terres 1980). Nestlings are altricial and downy; young are tended by both adults. Gregarious; may nest only 30 meters apart (Terres 1980).
Ecology Comments
Territory size in northcentral Colorado was 0.5-1.1 hectares (Wiens 1970, 1971; Finch et al. 1987). In South Dakota, territory size averaged about 0.2 hectares in idle mixed-grass and alfalfa fields (Pleszczynska 1977). However, territory size may be difficult to measure because unmated males will display within other males' territories (Finch et al. 1987).
