Spatial Relationships Between Coyotes and Red Foxes in Eastern Maine
Journal of Wildlife Management
We studied area use and spatial relationships among sympatric coyotes (Canis latrans) and red foxes (Vulpes vulpes) in eastern Maine during 1981-84. Foxes established home ranges outside of coyote territories or in boundary areas between adjacent coyote groups. Fox home ranges were associated with lakeshores or riparian zones, but foxes did not use these habitats within coyote territories. Foxes were never captured (>7,000 trap nights) within core portions of coyote territories. The presence of resident coyotes appears to limit the available habitat for red foxes in eastern Maine. Smaller spatial requirements enable foxes to persist in boundary areas between coyote territories and may prevent their complete displacement from regions occupied by coyotes.
