A large number of migratory birds have returned to Harbin as the weather warms up in mid-May. More than 100 species of birds have stopped over in Harbin to breed from May to September, according to Professor Wang Huai of Northeast Forestry University.
Here is a guide to Harbin's migratory birds provided by professor Wang:
Eurasian coot
Eurasian coots usually fly back to Harbin in mid-April and stay until late October. The birds are easy to find in suburban water areas of the city.
Yellow bittern
Yellow bitterns usually arrive in Harbin in mid-May. The birds can fly particularly fast and like to nest and reproduce in the reeds.
