Reproduction
& Life History:
The
swift fox is monestrous and usually breeds in late December or January.
After a mean gestation period of 51 days, a litter of 3-6 pups are
born in March or early April (Egoscue, 1979; Scott-Brown et al., 1987).
The pups emerge from the natal den at approximately 1 month and
continue to occupy the den throughout the summer, although their parents
may move them several times (Scott-Brown et al., 1987).
Dispersal of the young usually begins in August or September and
continues through the fall and winter.
Adult swift foxes usually live in pairs, although three adults may
sometimes raise a litter (Egoscue, 1979; Scott-Brown et al., 1987).
The swift fox has been described as the most subterranean of all
North American canids (Egoscue, 1979), and natal dens are usually located
on the more higher ground in an area.
The swift fox is primarily nocturnal, and diurnal behavior is
usually restricted to sunning activities around den sites (Kilgore, 1964).
