Each day, move to surrounding scrub communities for morning feeding, returning to dense, shady riparian areas by mid-day. In fall and winter, disperse to open shrub habitats on sloping and rolling terrain. They avoid rocky habitats and steep slopes. Move to riparian areas in summer. Home range size varies tremendously depending on season, age, sex, geographic location, and population density.
Summer ranges are smaller than winter ranges.
Home ranges of males and females overlap. Stable female groups do not form, unlike wild horses. Mating occurs yearlong, but peaks from May-July. The precocial young reach sexual maturity as yearlings. Native ungulates, in particular mountain sheep, are adversely affected by feeding activities.
