A Polish zoo recently announced the birth of four critically endangered Sumatran tiger cubs after initially keeping the news under wraps to ensure their survival.

The WrocÅ‚aw Zoo, located in southwestern Poland, revealed that the cubs were born on July 22. 

Polish Zoo Celebrates Birth of Endangered Sumatran Tiger Cubs

Zoo officials held off on sharing the news until the cubs had grown stronger and received necessary vaccinations. According to The Washington Post, this birth marks a significant milestone for the conservation of Sumatran tigers, which are critically endangered with only around 400 remaining in the wild.

The zoo has been breeding Sumatran tigers for decades and sees these births as crucial for conservation efforts.

"We wanted to make sure the cubs were strong and healthy before announcing their arrival," explained Weronika Łysek, the zoo's spokesperson. 

Since their birth, the four cubs, who are the offspring of mother Nuri and father Tengah, have shown excellent progress. Each cub now weighs over 8 kilograms (around 18 pounds), twice the size of an average domestic cat.

Male Cubs Bring Hope for Sumatran Tiger Population

Sergiusz Kmiecik, acting president of the Wrocław Zoo, shared his excitement about their development.

"The cubs are active, playful, and healthy, which is a fantastic sign of their growth," he said.

Father Tengah has taken an active role in caring for the cubs, a behavior that is uncommon for male tigers.

Paweł Sroka, head of the zoo's predatory mammals department, noted this rare occurrence. "Tengah has been gentle and supportive in caring for the cubs, something we don't often see in tiger fathers," he explained.

The litter consists of three males and one female, an important development as there is currently a predominance of females in European zoos. The arrival of the male cubs could help improve genetic diversity within the captive population. 

The zoo has yet to decide on names for the cubs and is considering involving visitors in the naming process. For now, the focus remains on ensuring the health and well-being of the cubs.

As MailOnline noted, Sumatran tigers continue to face significant threats from habitat destruction and poaching in the wild, and the Wrocław Zoo remains committed to their conservation through breeding programs and its dedicated tiger protection foundation.
