Polar bear rescued in Russia after getting tongue stuck in milk can

A polar bear roaming around an Arctic outpost in northern Russia has been rescued after getting its tongue caught in a can of condensed milk.

Residents of the remote settlement of Dikson sounded the alarm when the stricken 2-year-old female was seen wandering up to huts in the village on Wednesday.

A team from Moscow Zoo flew out to tranquillize the animal with a dart, remove the sharp metal from its mouth and treat the cuts to its tongue.

"The next important stage is her recovery from the anaesthesia. But our specialists will be nearby, watching the process," said Svetlana Akulova, director general of Moscow Zoo.

"We hope that everything will be fine. We left some fish near the bear because she had been without food and water for quite a long time," she said in remarks distributed by the zoo.

Mikhail Alshinetsky, a vet from the zoo, said the bear was thin and a little dehydrated but its injuries were expected to heal.

In a report this week, a team of Canadian and U.S. scientists warned that hungry polar bears are increasingly turning to garbage dumps to fill their stomachs as their icy habitat disappears due to climate change.

The scientists said human trash poses an emerging threat to vulnerable polar bear populations as the animals become more reliant on landfills near northern communities in places such as Russia, Canada and Alaska.
