Grey Fox

Physical Description

The grey fox is a smaller species with short, grizzled, grey fur with reddish highlights. Their average length from nose to the tip of their tail is 31-44 inches, and they will weigh anywhere from 7-13 lb.


Common predators they face are coyotes, bobcats, and large raptors, but they are known for being good at escaping. They will use their sharp claws and teeth to defend themselves.


In the wild, their average lifespan is 6-8 years, but in human care, they can live up to 15 years.


Usually, they will begin to form mating pairs in late winter and will breed in the spring. Grey Foxes are monogamous for the breeding season, and the couple will work together to support the offspring as they grow. The female will prepare the underground den while the male hunts. Their gestation period is approximately 2 months, and about 2-7 kits will be born.

Fun Facts

  • Their nickname is the “tree fox” because they are able to climb trees! They are 1 of only 2 species of the Canidae (dog family) able to climb trees.
  • They are primarily nocturnal but will hunt at dawn and dusk as well.

Conservation Messaging

Gray Foxes are not considered to be a threatened species but they do face habitat loss. Since these foxes live in areas with dense human populations, they are being driven out of their natural habitats by means of new development.
