The Amur tiger named Ustin, released into the wilderness in June 2014, has returned to Russia after a month spent roaming in China.

Tiger Special Inspectorate spokesman Viktor Serdyuk said Ustin had crossed the border on 16 December. Currently, the animal is on the Russian part of Bolshoi Ussuriysky Island in the Khabarovsk Territory.

The tiger is being tracked by specialists of the Russian Academy of Sciences’ Severtsov Institute for Ecology and Evolution, the Tiger Special Inspectorate, and the Russian branch of the Wildlife Conservation Society (WCS).

Ustin reached Bolshoi Ussuriysky Island on 11 November and spent several days there before crossing over into China. Specialists say the animal was seeking a permanent habitat.

Ustin is the second tiger to return to Russia in the past two months. In early December, a tiger named Kuzya crossed back into Russia across the ice-covered Amur River. After spending some time on the river’s bank, he headed north. Currently, the tiger is at the Dichuk game reserve in the Jewish Autonomous Region.
