While hiking a quiet trail near Estes Park, Colorado, 34-year-old nature enthusiast Katie Wilmer froze when a dark, shadowy figure darted across the path. “At first I thought it was a small bear cub,” she said. “But then it stopped and looked right at me — that’s when I saw the eyes and the long tail.”
What she had seen was a rare black-phase red fox, sometimes called a silver fox, a color morph so uncommon that many lifelong hikers in the Rockies have never seen one in the wild.
She snapped several photos from a safe distance before the fox slipped silently back into the trees. The encounter lasted only about 20 seconds — but it left a lasting impression.
What Is a Black Fox, Really?
Despite the name, this isn’t a separate species. The black fox is a melanistic variant of the red fox (Vulpes vulpes), caused by a genetic mutation that increases dark pigmentation. These foxes can appear black, charcoal, or silver depending on the light — hence the nickname “silver fox.”
Historically, silver foxes were highly prized for their fur, leading to over-trapping in the 1800s and early 1900s. Today, they’re protected in many areas, and spotting one in the wild is considered a rare treat.
“They’re like shadows — sleek, silent, and usually gone before you can even lift your camera,” said a Colorado Parks and Wildlife officer.
Why It Matters
Although they are found throughout Colorado, melanistic individuals comprise a small percentage of the population. Seeing one, especially in daylight and near a human trail, suggests either a highly adaptable animal or shifting behavior patterns.
Wildlife experts say human encroachment into natural areas may be pushing some animals to adjust their ranges or habits. Alternatively, it could just be a lucky encounter with an unusually bold fox.
“Either way, it’s a reminder to stay alert and respect what’s out there,” said the officer.
If You See One
For those hoping to spot a black fox — or any wildlife — safely and respectfully, follow these tips:
- Keep your distance: At least 20 meters (65 feet) away
- Don’t feed or follow: It disrupts natural behavior
- Use zoom, not your feet, to get photos
- Report unusual sightings to your local wildlife office — it helps track populations
Katie, who’s hiked dozens of Colorado trails, says this was her most memorable sighting yet. “It looked straight through me. I don’t think I’ll ever forget that.”
