Wild condors inhabit large territories, often traveling 250 kilometers (150 mi) a day in search of carrion.[25] In the early days of its existence as a species, it is thought that the California Condor lived off of the carcasses of the "megafauna", which are now extinct in North America.
They still prefer to feast on large, terrestrial mammalian carcasses such as deer, goats, sheep, donkey, horse, pigs, mountain lions, bears, or cattle. Alternatively, they may feed on the bodies of smaller mammals, such as rabbits or coyotes, aquatic mammals, such as whales and sea lions, or salmon. Bird and reptile carcasses are rarely eaten. Since they do not have a sense of smell,[26] they spot these corpses by looking for other scavengers, like smaller vultures and eagles, who cannot rip through the tougher hides of these larger animals with the efficiency of the larger condor. They can usually intimidate other scavengers away from the carcass, with the exception of bears, which will ignore them, and Golden Eagles, which will fight a condor over a kill or a carcass.[14] In the wild they are intermittent eaters, often going for between a few days to two weeks without eating,[25] then gorging themselves on 1–1.5 kilograms (2–3 lb) of meat at once, sometimes to the point of being unable to lift themselves off the ground.[27]
