A den used by a family of foxes has been discovered less than 20 feet from Burr Elementary School.

A school employee called police last Friday after a red fox was spotted behind the school at 1960 Burr St., and animal control officers found the animal’s den. There have been no encounters reported between the foxes and students or anyone else in the neighborhood, police said.

School officials were advised by the state Department of Energy and Environmental Protection to call a wildlife specialist in order to relocate the foxes

According to the DEEP website, red and gray foxes are both native to Connecticut and, if healthy, pose no danger to humans.

The red fox can often been seen in forest and open fields, and it is not unusual for the animal to be spotted during the daytime. A human presence will often inhibit red foxes from inhabiting an area.

The gray fox is seen less frequently, because of its reclusive and nocturnal nature.

Pets should be kept indoors as a precaution if there is a fox nearby, according to the DEEP.
