A rare mule deer fawn with striking blue eyes and a light-colored coat has been spotted near La Barge, Wyoming, captivating wildlife enthusiasts. The fawn, part of the Wyoming Range mule deer herd, is believed to have leucism—a genetic mutation causing reduced pigmentation—resulting in its unusual appearance.
Local wildlife observer Jeff Orvin first noticed the fawn on the herd’s winter range. Despite its distinctive look, the fawn appears healthy and well-nourished. Leucism differs from albinism; while both result in lighter coloration, leucistic animals can have partial pigmentation and typically retain normal eye color, whereas albinos lack pigmentation entirely and often have red or pink eyes.
The Wyoming Range mule deer herd, known for producing some of the largest bucks in the state’s history, suffered significant losses during the harsh winter of 2022-2023, with up to 80% mortality, including nearly all fawns. However, the herd is showing signs of recovery, with a notable increase in fawn numbers this year. The Wyoming Game and Fish Department reports approximately 82 fawns per 100 does, indicating a strong rebound.
While leucistic deer often face survival challenges in the wild due to their conspicuous appearance, which can attract predators, this particular fawn’s robust health offers hope for its continued growth and contribution to the herd’s resurgence.
