Born on June 13, the cubs are currently bonding with their mother, Sakura, in a nest of bamboo within the Zoo’s red panda facility, under the careful observation of wildlife care staff through nestbox cameras.
Sakura, the only red panda at Toronto Zoo, was considered to be in retirement after previously being deemed less likely to conceive due to age and a history of unsuccessful breeding seasons. Unexpectedly, Sakura became pregnant following her last breeding period with her former mate, Arun, before her transfer to Toronto. The zoo’s reproductive science team confirmed her pregnancy through hormone analysis of her fecal samples.
Per the media release, determining pregnancy in red pandas involves complex challenges due to their unique reproductive traits, including pseudopregnancies and delayed implantation. Sakura’s pregnancy was confirmed via ultrasound only a week before she gave birth, a method that revealed the development of the cubs late in the term due to the species’ reproductive peculiarities.
Red pandas are notoriously difficult to breed in captivity and have a high rate of cub mortality. Studies indicate that up to 40% of pregnancies in red pandas result in early loss, and the survival rate for cubs is similarly low. These challenges are compounded by the threats of illegal hunting and habitat loss in the wild, underscoring the importance of conservation efforts.
In response to these challenges, Toronto Zoo has engaged in a partnership with the Red Panda Network to support conservation initiatives aimed at stabilizing and eventually increasing the red panda population in their natural habitats, which are estimated to number between 2,500 and 10,000.
