Colombian Weasel

Mustela felipei

Also known as Don Felipe's Weasel

Colombian weasels are exceptionally secretive montane carnivores distinguished by extensive webbing on their feet, an adaptation suggesting strongly semi-aquatic habits along mountain streams. Their rich dark brown pelage contrasts sharply with an orange-buff belly marked by a distinctive dark spot on the chest. Known from barely a dozen recorded encounters in high-elevation cloud forests, they rank among the rarest and least understood small carnivores in South America.

Support conservation
Avoid disturbing stream banks, keep noise to a minimum, and share exact coordinates only with researchers.
Responsible observation
  • Riparian scouting: Watch quiet, densely vegetated stream banks in high-elevation cloud forest reserves.
  • Camera trapping: Position motion-activated cameras near undisturbed mountain creeks and fallen logs.
  • Report sightings: Document any photographic encounter with local conservation biologists and park rangers.
