Ecology & Habitat

Habitat

Very adaptable; may be found in most habitats. Prefers wooded riparian habitats. Also in suburban areas. Abandoned burrows, buildings, hollow logs, and tree cavities are generally used for den sites. In southeastern New York, all weaning dens were in burrows; weaning dens were in more densely vegetated habitats than were nonweaning dens (Hossler et al. 1994).

Ecology

Populations typically include a high percentage of young. Winter density was 1/9.9 ha and 1/44.5 ha at two locations in Tennessee (Kissell and Kennedy 1992).

Reproduction

U.S. mating season January-July. Commonly 2 litters/year, sometimes 3; usually 1/year in north. Gestation lasts 13 days. As many as 23 offspring may compete for 13 or so teats. Average of 8-9 young are weaned after 10-12 weeks. Sexually mature at 9 months. Juveniles experience a high rate of mortality (Hossler et al. 1994). Females seldom live through more than one reproductive season.
