Wolves may kill and eat red foxes in disputes over carcasses. In areas in North America where red fox and coyote populations are sympatric, red fox ranges tend to be located outside coyote territories. The principal cause of this separation is believed to be active avoidance of coyotes by the red foxes. Interactions between the two species vary in nature, ranging from active antagonism to indifference. The majority of aggressive encounters are initiated by coyotes, and there are few reports of red foxes acting aggressively toward coyotes except when attacked or when their kits were approached. Foxes and coyotes have sometimes been seen feeding together. In Israel, red foxes share their habitat with golden jackals. Where their ranges meet, the two canids compete due to near-identical diets. Red foxes ignore golden jackal scents or tracks in their territories and avoid close physical proximity with golden jackals themselves. In areas where golden jackals become very abundant, the population of red foxes decreases significantly, apparently because of competitive exclusion.
