CCTV News noted that May to September is the peak breeding season for tigers and leopards. Since August, two new Siberian tiger families have been recorded within the Park, bringing the total number of newborn Siberian tiger cubs to seven.
 
Monitoring records indicate that endangered wild animals, such as the Siberian tigers and Amur leopards are reproducing and growing steadily in the park.
 
In the latest monitoring data, an infrared camera captured the five-member family together in a single frame. It was the second time such footage has been recorded since the park launched its pilot work for nature reserves in 2017, according to the report.
 
This family was spotted in Hunchun Mountain, Northeast China's Jilin Province. A Siberian tigress was patrolling the mountain with her cubs when they triggered an infrared camera set up by the roadside. Under the camera’s flash, the tigress was seen walking to the water’s edge, bending down to drink, followed closely by her cubs.
 
Female Siberian tigers usually give birth to two to four cubs per litter, making four cubs in the wild is extremely rare, CCTV News reported.
 
Over the past decade, the strict protection of the national park system has steadily improved the habitat for wild tigers and leopards, according to CCTV News.
 
Populations of hoofed animals, such as sika deer and roe deer, which are the main prey of tigers and leopards, have also risen, boosting the survival rate of tiger and leopard cubs. 
 
The survival rate of wild tiger and leopard cubs has increased from about 30 percent to over 50 percent, said Duan Zhaogang, director of the Northeast China Tiger and Leopard National Park Administration.
 
A rare video of two tigers fighting was also captured by infrared camera.
 
In the footage, an adult Siberian tiger is seen walking slowly and sniffing the ground, seemingly aware of approaching danger. At that moment, another Siberian tiger unexpectedly appears in the frame, approaching from the opposite direction.
 
When the two tigers met, they engaged in a brief standoff before charging at each other, roaring and tussling. The first tiger defeated its opponent and drove it back.
 
Based on previously recorded videos, monitoring personnel believe that the two tigers are likely a mother and her daughter. The mother’s aggressive activity may be an attempt to encourage the young tiger to leave, become independent, and establish her own territory, the report said.

Since 2018, the park’s monitoring system has recorded 30,000 instances of wild Siberian tigers and 41,000 of Amur leopards, CCTV News reported.
