Tens of thousands of wild geese and other migratory birds have arrived at the wetlands that strech along Yellow River in central China.

Staff at the Yellow River Wetland National Nature Reserve in Changyuan City of central China's Henan Province said that the flocks arrived about one week later than previous years due to the warm weather this winter.

So far, over 50,000 birds have been recorded in the reserve, with more on their way.
