Scientists have taken new photographs of the tigress Serga. Prime Minister Vladimir Putin helped fit her with a satellite tracking collar in 2008. This effort is part of the Amur Tiger Programme implemented by the Severtsov Institute of Ecology and Evolution, part of the Russian Academy of Sciences.

The pictures, which show her in the company of three cubs all around 3-4 months old, were taken on January 17, 2011, by camera traps in the Ussuri Reserve. Serga reproduced successfully in 2008: giving birth to two male cubs and one female cub. One of her cubs, named Boxer, was caught on October 26, 2009 so a satellite collar could be fitted, shortly before he left the area inhabited by his mother.

Serga spent most of the autumn in the southern part of the Ussuri Reserve, probably because she had a lair there where she was nursing her cubs.
