BEIJING -- A rare Siberian tiger released into the wild by Russian President Vladimir Putin is keeping farmers in northeastern China on edge.
China's official Xinhua News Agency said Wednesday that the animal, named Ustin, bit and killed 15 goats and left another three missing on Sunday and Monday on a farm in Heilongjiang province's Fuyuan county.
Xinhua said the farm's owner, Guo Yulin, was stressed about the tiger, but that he would be compensated by the local forestry department for the loss of the 18 goats.
According to Xinhua, Russian experts rescued five tiger cubs two years ago. Ustin was one of three released by Putin in May in a remote part of the Amur region, which straddles the border between far eastern Russia and northeastern China.
Two of the tigers entered China. They were fitted with tracking devices and are monitored by Chinese wildlife protection workers.
The other tiger to enter China, Kuzya, was believed to have raided a farm and eaten five chickens last month in another Heilongjiang county.
Guo told Xinhua that he was alerted by dog barks on Sunday night, but that his check turned up nothing unusual. He said he woke up the next morning to find two goats dead and three others missing.
Xinhua said the goats' skulls were crushed by the tiger and that a hole the size of a human finger was visible on each goat's head.
The farmer said the tiger returned the following night but made no noise at all.
"When I opened the goat house in the morning, dead goats were everywhere," Guo said, according to Xinhua.
Local experts found the tiger's footprints around the goat house and on its roof, Xinhua reported. Guo was asked to either relocate his goats or reinforce his farm, it said.
In 2009, a Russian environmentalist reported that a Siberian tiger fitted by Putin with a radio-tracking collar vanished.
Last month, Putin - who topped Forbes' "Most Powerful People" list this year-- celebrated his 62nd birthday in the wilderness of Siberia. The Russian leader has often brandished his tough-guy image with widely publicized wilderness romps during which he hunts, fishes or rides horses - often while shirtless.
