Inga Brennan of Golden submitted this photo in March 2008 of a "silver/red fox hybrid" ("very likely a genetic mix between wild red fox and fur farm escapees generations ago.") She writes that "this fox is on Lookout Mountain where there used to be fur farms back in the 40s and 50s. Some animals escaped to breed with wild populations, and occasionally one may see an unusual coat color. I have also seen a pure black one here, as well." "This silver male has bred with a red female who is denning under my deck and we believe she has recently given birth. It will be exciting to see the kits & what colors they turn out to be!"
