San Diego Zoo Wildlife Alliance is celebrating the birth of two Sumatran tiger cubs—the first of this endangered species to be born at the San Diego Zoo Safari Park’s Tull Family Tiger Trail habitat in seven years.

The cubs, a female and a male, were born July 12 to first-time mother Diana.

Wildlife care specialists are closely monitoring Diana and her cubs, and they report that Diana is an extremely attentive and gentle mother. The cubs appear strong, and are nursing frequently.

We are elated about the birth of these tiger cubs.”

“We are elated about the birth of these tiger cubs,” said Lisa Peterson, executive director, San Diego Zoo Safari Park. “It has been years since we’ve had cubs at Tiger Trail, and we can’t wait to share them with the community.”

Sumatran Tiger Species Survival Plan

The births are a result of a breeding recommendation through the Association of Zoos and Aquariums’ Sumatran Tiger Species Survival Plan (SSP).

Each SSP program, overseen by conservationists nationwide, ensures genetic diversity and healthy, self-sustaining assurance populations of threatened and endangered wildlife.

Sumatran tigers are listed as Critically Endangered on the International Union for Conservation of Nature Red List of Threatened Species.

Tigers face many challenges, including loss of habitat, challenges to human-wildlife coexistence and poaching.

Zoo officials say people can help protect tigers by avoiding products made with non-sustainable palm oil, an industry that harms tiger habitats; and by refusing to purchase items made from endangered wildlife.

Diana and her cubs will remain in her den for several weeks. This window of time is crucial, as it allows the youngsters to bond with and learn from their mother. When Diana is ready, she will bring her cubs out of the den. Wildlife care specialists estimate this will happen when the cubs are 8 to 10 weeks old.
