Red Fox Vixens Preparing Dens
With their breeding season nearly at an end, red fox vixens are preparing for the arrival of a litter of pups in March or April. This involves locating and cleaning several dens, and then choosing one in which to give birth and raise young. An adult female red fox may use the same den year after year; eventually one of her daughters may take it over.
While specific den locations vary, most are on sandy hillsides, often in the woods but close to an open area, and usually there is water within 300 feet or so. A den typically has several entrances, with the main one measuring about ten inches in diameter. At this time of year (if there is snow on the ground) it is relatively easy to locate fox dens, due to soil that has been removed and scattered on the snow.
Vixens often renovate an abandoned woodchuck burrow, but occasionally den underneath an outbuilding, in a hollow log, rock pile or other sheltered area. Pictured are a typical hillside den as well as an abandoned beaver lodge that has been renovated by a fox. Scat (located about 2 o’clock in the photo) deposited near the entrance of the lodge indicates that this may well be a den that will be used for raising young.
