Introduction to Swift Fox
The Swift Fox is small, sand-coloured and lives in open shortgrass prairie with nowhere to hide. It survives by using burrows year-round — the only North American canid that does — so the cover it lacks above ground it keeps below it.
How to identify a Swift Fox
Why Swift Fox are interesting
- It is the only canid in North America that uses burrows all year rather than only in the breeding season.
- It can run at around 50 km/h in short bursts, which is where the name comes from.
- It was nearly eliminated from the northern prairies by the 1930s and has been re-established in parts of Canada by reintroduction.
- A single fox maintains several dens across its range and moves between them, which limits how well any predator can predict it.
- It is roughly half the weight of a Red Fox, at about 2-3 kg.
02
Adaptations and biological abilities
03
Why does Swift Fox behave this way?
- Very small fox, about the size of a domestic cat
- Sandy buff coat with black patches either side of the muzzle
- Large ears and a black-tipped bushy tail
- Uses dens year-round, not only for raising young
Mostly nocturnal, resting in a den through the day and emerging around dusk, though it will sun itself at a den mouth in cold weather.

Why Native range keys: north_america. Shortgrass and mixed-grass prairie of the Great Plains?
Habitat: Native range keys: north_america. Shortgrass and mixed-grass prairie of the Great Plains, on flat open ground with soil loose enough to dig. The habitat has essentially no above-ground cover, which is what makes the burrow strategy necessary rather than optional.
Native range: Native range keys: north_america. Shortgrass and mixed-grass prairie of the Great Plains, on flat open ground with soil loose enough to dig. The habitat has essentially no above-ground cover, which is what makes the burrow strategy necessary rather than optional.

05
Why this diet?
Rabbits, prairie dogs, ground squirrels, insects, birds and grasses, hunted mostly at night. Foraging in the open at night, with a den never far away, is the pattern the whole life is built around.
06
Activity, rest, and lifespan
Mostly nocturnal, resting in a den through the day and emerging around dusk, though it will sun itself at a den mouth in cold weather.
Three to six years in the wild, and up to fourteen in captivity.
07
Swift Fox reproduction
Four to five kits born in a den in spring. Both parents provision them, and the family moves between dens through the summer as the kits grow.
Males and females look alike; males average slightly larger, by a margin not usable in the field.
08
Predators, threats, and defense
Coyotes are the main cause of death, plus Golden Eagles and badgers. Coat colour helps a little; the dens do most of the work, and having several of them is the reason a coyote cannot simply wait one out.
09

Where to find them
Where to find Swift Fox
To find Swift Fox in the wild, focus on the exact habitat patches that match its body design and daily behavior, not just the broad country where it exists. You usually do better by working one good piece of habitat inside native range keys: north_america. Shortgrass and mixed-grass prairie of the Great Plains, on flat open ground with soil loose enough to dig. The habitat has essentially no above-ground cover, which is what makes the burrow strategy necessary rather than optional. than by covering too much ground.
- Open grassland edges, lightly wooded plains, or raised ground where you can scan long distances
- Burrow systems, sandy banks, fallen logs, or ground with clear den entrances
- Protected habitat blocks within native range keys: north_america. Shortgrass and mixed-grass prairie of the Great Plains, on flat open ground with soil loose enough to dig. The habitat has essentially no above-ground cover, which is what makes the burrow strategy necessary rather than optional.
