Sometimes, they hunt by day. They are the only canines that can climb trees. They seek refuge in trees and also climb to find food. The bark of the gray fox sounds like a hoarse cough. If you startle a fox, it may bark at you.
Foxes are omnivorous.
They eat small mammals, birds, insects, eggs, fruit, nuts, grains, and even human garbage. Rabbits are a preferred prey animal. In campgrounds, you might see them at night, picking through fire rings in search of morsels from campers' meals. They are frequently seen crossing roads at night. In towns, they often eat pet food.
