Due to severe frosts, thousands of swans are starving in China

A recently published video shows how thousands of swans in search of food are walking on the surface of the frozen Yellow River. The severe frosts established in the Chinese province of Shanxi cut off a huge population of swans from food sources.
Thousands of birds go on a hike in search of food. Local authorities do not stand aside and have already prepared tons of corn and other food to help the birds survive the hard times.
