Kids enjoying a day off from school aren't the only ones who enjoy a snow day.

Reston photographer William O'Brien took these photos of a red fox near his home on appropriately named Foxcroft Way in Reston Tuesday morning. The neighborhood is near Soapstone Drive and Lawyers Road. One of the photos was originally published on the Reston Association Facebook page today.

Here's more about foxes in Fairfax County, courtesy of the county: Red foxes (Vulpes vulpes) are 35 to 48 inches long (nose to tail), stand higher than a large cat or small dog, and weigh 7 to 17 lbs. Body color ranges from grayish-red to bright red in color and have a white tail tip.

Gray foxes (Urocyon cinereoargentus) are smaller than a red fox, are 31 to 44 inches long (nose to tail) and weigh 7 to 10 lbs. Body color ranges from dark gray to reddish-gray and have no white on their tail tip.

Behavior

Foxes generally pose little threat to humans, their property or pets. Large red foxes have been known, in some cases, to prey on small cats. It is always advisable to feed pets indoors and to keep small pets inside or securely penned at night.

Foxes are primarily nocturnal. Foxes are highly adaptive and can become increasingly active during the day in urban areas.

Foxes establish bonded pairs to breed in January or February and raise young together. Gestation is 7 to 8 weeks. Red foxes establish maternity dens in previously used sites. Gray foxes establish maternity dens in hollow logs, rock piles, or small caves. Dens are only used to rear young. Young foxes become independent by 6 months of age. Diet
