The Santa Barbara Zoo in California announced the death of the second of two red panda cubs born earlier this summer. The cub passed away over the weekend. This follows the death of another cub, which was found by zoo staff on July 21. These were the first cubs of the red panda named Ruby.
The zoo staff shared that red panda cubs experience a high mortality rate, with around 40% not surviving. The cubs were born on July 2, and the surviving cub was under intensive care, receiving attention from veterinary and animal care teams around the clock. Despite these efforts, the second cub could not be saved.
The cause of death is still under investigation. The zoo expressed deep sorrow over the loss, acknowledging the heartbreak felt by those who cared for the cubs and their supporters.
Ruby and her cubs were initially housed together in a nest box. The zoo intervened on July 19 when staff observed that the cub was not nursing properly. The cub was separated from Ruby and received critical care in a temperature-controlled environment, including tube and bottle feedings, antibiotics, and constant veterinary supervision.
The red pandas, Ruby and Raj, will not have another breeding opportunity until next year due to their seasonal breeding patterns. The zoo emphasized the importance of conservation efforts to protect endangered species like red pandas.
These animals are slightly larger than house cats and face numerous threats. According to the World Wildlife Fund, they are endangered largely due to habitat loss in the eastern Himalayas and accidental trapping in devices meant for other animals. The zoo estimates fewer than 10,000 mature red pandas remain in the wild.
Efforts to breed and care for red pandas in captivity are crucial to preserving the species, given the challenges they face in their natural habitat.
