Gray foxes, Urocyon cinereoargenteus, are omnivorous members of the canine family. Their diet ranges from mammals and birds to invertebrates, fruits, and nuts depending on the season and what is available.
As you can see from the figure above, we didn’t catch any on camera from 7 a.m. to 6 p.m. There could be many factors that explain this. Gray foxes are really good tree climbers, and we didn’t have any cameras in trees. Also, this species of fox is primarily nocturnal. We have written about their tree-climbing ability as well as their avoidance behaviors here.
Above you can see that they didn’t overlap much with coyotes in space. It almost looks as though the coyotes have pushed the gray foxes closer to developed area. Gray foxes also tend to avoid coyotes in time, only overlapping 55% of the time. This strategy is used to avoid interactions with the much larger carnivore, the coyote.
We also found that gray foxes were:
- Present at 6 trap stations
- Found in 96 photos (30 independent observation)
- Nocturnal 96.67% of the time
