“Rare Dalmatian pelicans, a threatened species, are dying of cold and hunger amid freezing weather in Russia’s usually warm Dagestan, where the birds are currently wintering,” says this article RiaNovosti.
The birds flew to Makhachkala last week from the frozen deltas of the Volga and Terek rivers up north.
Unfortunately, temperatures of minus 20-30C (-4 to -22 F) have swept Russia’s southern latitudes, leaving the Caspian Sea coated in a thick layer of ice.
