Red foxes (Vulpes vulpes) avoid areas used extensively by coyotes (Canis latrans), apparently to reduce encounters with coyotes and possible injury or death. It is conceivable that kit foxes (Vulpes macrotis) behave in a similar manner. We used telemetry to examine the spacing patterns and interactions among 24 coyotes and 38 San Joaquin kit foxes (V. m. mutica) in California during a period of declining and low prey abundance (1989–1991). Coyotes showed either territorial (n = 13) or transient (n = 11) spacing patterns, whereas all kit foxes were territorial. Spatially and temporally, coyote home ranges overlapped >30% of each fox home range. Both species used the overlap areas more than expected (P < 0.001), possibly because prey such as kangaroo rats were more abundant in these areas. Fifty-five percent of the areas used extensively by foxes during their nocturnal activities were overlapped by coyote nocturnal-use areas. Concurrently monitored coyotes and foxes that occupied overlapping home ranges (n = 25 combinations) were neither farther apart nor closer together than expected (P = 0.09–0.87), even when the coyote was in the fox's home range. Kit foxes did not avoid coyotes and may be able to coexist with them by exploiting certain prey species better than coyotes and maintaining numerous (≥20) dens throughout their home ranges to facilitate escape. Apparent differences in coyote – red fox and coyote – kit fox relations may be partially attributed to differences in resource selection and predator-avoidance strategies among fox species.
