China is a good place to see bitterns. In addition to the Great Bittern (the one familiar to European readers), it is also possible to see Black Bittern, Cinnamon Bittern, Von Schrenck’s Bittern and Yellow Bittern. Of the smaller bitterns, the Yellow Bittern is most numerous in Beijing with Von Schrenck’s also breeding in small numbers. Cinnamon is an occasional (and increasing?) late Spring visitor (and possible breeder?) and there is just one record of Black Bittern.
Below are some images of Cinnamon, Von Schrenck’s and Yellow Bitterns, all taken in Beijing or neighbouring Hebei Province.
First, the beautiful richly coloured Cinnamon Bittern.
Next up, Von Schrenck’s Bittern. The males and females look quite different.
Finally, the Yellow Bittern. A common breeder, including in the Olympic Forest Park and Yeyahu NR.
