The Legacy of Tilly: A Beloved River Otter at Oregon Zoo
On April 30, 2025, the Oregon Zoo bid farewell to Tilly, its oldest North American river otter, who passed away peacefully at the age of 16. This event marks not only the loss of a beloved animal but also highlights the significant bond between such creatures and their caretakers. Tilly’s life story is a testament to resilience and maternal love that resonated with both zoo staff and visitors alike.

Found orphaned and injured along Johnson Creek in 2009, Tilly's journey began under dire circumstances. She was rescued by the Oregon Department of Fish and Wildlife and transferred to the zoo, where she would go on to become a remarkable figure. Jen Osburn Eliot, the overseer of the zoo’s North America area, reflected on Tilly’s difficult beginnings, stating how this little pup overcame adversity and grew into a nurturing mother for her own offspring and adopted pups.
Tilly’s parenting prowess was nothing short of exceptional. Throughout her life, she raised four pups, Mo, Ziggy, Tucker, and Nellie. In 2013, she was even honored with the "Mom of the Year" award at the zoo, not only for her devotion to her biological pups but also for her willingness to foster orphaned youngsters like Flora and Hobson. According to Eliot, “Young river otters are extremely dependent on their mothers, and Tilly not only raised her own offspring but others who lost their moms and needed a second chance.”

Aside from her nurturing role, Tilly's charm transcended the boundaries of the zoo. She gained national attention through her cameo in the popular sitcom "30 Rock," where she was noted for her comical resemblance to actor Tracy Morgan. This added another layer of fame to her already colorful story, captivating a broader audience beyond the usual zoo visitors.
As a geriatric river otter, Tilly was euthanized due to age-related decline, a difficult decision that her caretakers had to make considering her quality of life. With a median life expectancy of just 12.9 years in captivity, Tilly surpassed those expectations, living a full life enriched by love and care.
The legacy of Tilly transcends her physical presence; she represents the intricate relationship between animals and humans, reminding us of the responsibilities we hold towards wildlife. Tilly’s story invites reflection on conservation and the ongoing efforts to protect species that are still facing challenges in their natural habitats. Her contribution to educational outreach will remain as a loving memory for all who knew her.
