Behaviour
It is mostly nocturnal and crepuscular, with normal daylight activity at times. It uses habitats including woodland, brushy edges, farms and wooded suburbs. It feeds on small mammals, insects, fruit, birds and carrion.
Foxes hunt with hearing and scent, often pausing to listen before pouncing on prey hidden in grass or leaf litter. They also eat fruit and insects, so their diet shifts with season.
Gray foxes are the only North American canids that routinely climb trees.
Why they matter
Foxes suppress populations of mice, voles and other small mammals while also dispersing seeds from fruit. They are flexible mid-sized predators in both rural and suburban food webs.
A fox's large ears are not decoration: precise sound localisation helps it detect prey it cannot see.
Reproduction and lifecycle
Mating — mainly winter, often December through February, later in the north.
Gestation — about 51–53 days.
Pups — commonly 3–6 are born in a den in late winter or spring.
Dependency — pups begin emerging after roughly 4–5 weeks and remain with the family through summer.
Dispersal — young usually leave the natal area in autumn.
Living around people
- Keep small pets supervised, especially around dawn, dusk and night.
- Secure pet food, rubbish and fallen fruit so foxes do not learn to forage beside homes.
- Give dens with pups quiet space; parents may move young if repeatedly disturbed.
- Drive carefully on rural and suburban roads at night.
Misconceptions
- A fox seen in daylight is probably rabid. Healthy foxes may be active by day, especially when feeding growing pups; concern should focus on neurological signs rather than the clock.
- Foxes are looking for people to attack. They normally avoid close contact and focus on small prey and available food.
- Feeding a fox helps it survive. Regular handouts can reduce normal distance from people and increase conflict risk.

| Notes | Peak courtship and mating season; pairs may travel and vocalise more. | Mating continues and females begin pregnancy. | Pregnant females select dens; some litters are born late in the month. | Pups remain close to dens while adults make frequent food trips. | Growing pups begin appearing outside dens and playing nearby. | Family groups range more widely as pups learn to hunt. | Young continue developing hunting skills and eating more solid food. | Juveniles travel farther from the den and family movements broaden. | Young begin becoming more independent. | Autumn dispersal increases road crossings and unfamiliar sightings. | Adults settle into winter ranges; prey and fruit remain important foods. | Courtship activity begins increasing again late in the month. |
