Two of the San Francisco Zoo’s most recognizable residents were euthanized today, leaving staff and regular visitors grieving the loss of an aging lemur and a one-of-a-kind penguin. Eno, a 34-year-old red-bellied lemur, and Freckles, a 19-year-old Magellanic penguin, were both put down after suffering from serious health problems that could not be reversed.
In a statement to KRON4, the San Francisco Zoo said Eno had been diagnosed with kidney disease and was euthanized after a rapid decline, with pathology testing still pending. The zoo believes Eno was the last red-bellied lemur in North American zoos, and he had been a familiar face at the institution for decades. According to the zoo, Freckles developed neurological symptoms and breathing issues beginning in mid-December that did not improve despite intensive veterinary care.
Eno’s Final Days and Legacy
Keepers said Eno’s health deteriorated steadily, and his advanced age combined with his medical problems meant he was no longer able to rebound to a quality of life the staff considered acceptable. Over the years, he served as an ambassador for his species to countless zoo visitors, and his death further shrinks an already limited population of red-bellied lemurs in captivity. Staff are waiting on postmortem test results to better understand what may have triggered his sudden downturn.
Freckles’ Struggles and His Mate Frenchie
Freckles stood out in the penguin colony because of his leucism, a genetic pigment variation that left him mostly white with black spots. The zoo told KRON4 that he had fathered four offspring. In his final weeks, caretakers observed neurological signs that left him disoriented and at serious risk of drowning if he were allowed into the colony pool, which led to the difficult decision to euthanize him. His longtime mate, Frenchie, is being closely watched by animal care staff as she adjusts to his absence.
Staff Reaction and Next Steps
Zoo leaders said both animals played an outsized role in educating and inspiring millions of visitors over their many years at the park. Veterinary teams will continue diagnostic testing and plan to share results with the public once they are available. For now, keepers say they are focused on monitoring the rest of the colony and offering extra attention to animals that may be affected by the losses.
For official updates and detailed statements, the public can visit the San Francisco Zoo. The institution said it is grateful for the community’s concern as staff complete postmortem testing and mourn the passing of Eno and Freckles.
