The Sacramento Zoo is currently mourning the passing of one of its most beloved residents, Ewell, a 54-year-old white-handed gibbon. Ewell was humanely euthanised on March 19, 2023, following a decline in health attributed to age-related conditions. His death comes just weeks after the zoo lost his daughter, Siidam, who passed away on March 2.

In an official statement released on Facebook, the zoo provided details about Ewell’s health struggles leading up to his demise. Caretakers noted they had been closely monitoring the gibbon’s wellbeing as he faced multiple age-related issues, including arthritis and deteriorating vision. The staff expressed how these health complications played a significant role in the decision to euthanise him.
Ewell had been a fixture at the Sacramento Zoo since 1976, making him not only a long-standing resident but also a favourite among both the staff and zoo visitors. The gibbon far exceeded the typical lifespan of his species, which usually ranges around 40 years, marking him as the oldest male white-handed gibbon in any institution accredited by the Association of Zoos and Aquariums (AZA).

The zoo’s statement highlighted the exemplary care Ewell received over the years, which contributed to his remarkable longevity. The commitment and professionalism demonstrated by the animal caretakers were acknowledged as critical factors in ensuring Ewell’s comfortable and extended life. Such dedication to animal welfare has made the zoo a welcoming and nurturing environment for its residents.
Ewell’s passing has left a significant void at the Sacramento Zoo. In their announcement, the management reflected on the profound impact both Ewell and Siidam had made during their time at the facility. They expressed deep sympathy for staff members who developed close bonds with Ewell and his family, calling for the community to support them through this challenging period.
The loss of Ewell resonates beyond the confines of the zoo, as many visitors fondly remember their encounters with him. His playful nature and charming personality have captured the hearts of countless families throughout the years. It is these shared experiences that create lasting memories for both the zoo’s patrons and the staff who have cared for him throughout his life.
In remembering Ewell, the zoo aims to celebrate his life and the joy he brought to all who encountered him. The staff is dedicated to honouring his legacy by continuing to raise awareness about the plight of white-handed gibbons and other endangered species. Educational programs at the zoo will highlight the importance of conservation efforts, ensuring that the lessons learned from Ewell’s life will not be forgotten.
As the Sacramento Zoo navigates through this time of loss, it remains committed to providing quality care for its remaining residents and fostering a love for wildlife in the community. The memory of Ewell, alongside the care and compassion displayed by the zoo’s team, will continue to inspire their mission of animal welfare and education.
