Wolf 907F is the alpha female of the Junction Butte pack in Yellowstone’s Northern Range. Her advanced age and continued reproductive success have made her a notable figure among researchers studying wolf populations.

An Impressive Record of Reproduction

Since becoming sexually mature, Wolf 907F has given birth to a litter of pups every year for the past decade. This consistent reproduction is likely a record for wolves in Yellowstone, showcasing her extraordinary vitality.

Challenges of Aging in the Wild

The average lifespan of gray wolves in the wild is three to four years, making Wolf 907F’s 11 years of life, combined with her ongoing reproductive success, particularly remarkable. Very few wolves reach this age, and even fewer continue to reproduce.

Survival Against the Odds

Only about 1 in 250 wolves in Yellowstone make it to 11 years old. Wolf 907F is one of the oldest wolves recorded in the park, with her longevity attributed to both her resilience and the support of her pack.

The Role of Experience

Older wolves like Wolf 907F bring valuable experience to their packs, especially in navigating territorial disputes and hunting. Her knowledge and skills have likely contributed to the success and stability of the Junction Butte pack.

Defending Territory and Leading the Pack

As the alpha female, Wolf 907F plays a critical role in defending the pack’s territory and leading them in hunts. Despite her age and physical challenges, her leadership remains a cornerstone of the pack’s survival.

Life with One Eye

Wolf 907F has been living with only one functioning eye since before she turned 4. Researchers do not know the cause, but her impaired vision has not hindered her ability to thrive and lead her pack.

Smaller Litter Size with Age

This year, Wolf 907F gave birth to a smaller litter of three pups, which is fewer than the average litter size of four to five. A decrease in litter size with age is expected among older wolves.

Raising the Next Generation

Despite Wolf 907F’s successful reproduction, many of her pups do not survive to adulthood due to the harsh realities of life in the wild. Predation, disease, and competition are constant threats.

The Significance of Elder Wolves
