Comments: Carrion; feeds primarily on a variety of small, medium and large mammal carcasses, including those of weasels, kangaroo rats, sheep, cattle, deer, ground squirrels, horses, coyotes, rabbits, etc. (Collins et al. 2000; Terres 1980). Apparently very few birds and reptiles are scavenged (Collins et al. 2000). May eat 1-1.3 kg of meat/day (Terres 1980). Prefers fresh meat. Feeds on ground. Requires fairly open terrain for feeding (to facilitate take-offs and landings). Regularly locates food by presence of eagles and ravens (Matthews and Moseley 1990).
