Title: White-breasted Waterhen 白胸苦惡鳥

101 White-breasted Waterhen 白胸苦惡鳥
Mai Po 米埔
A white-faced "Moorhen" wandered on MaiPo Deep Bay mudflat with four other Moorhens.

Is it really a Moorhen? Why is its face white?

The face is white because it is a young bird.

Thanks for sharing.

But is there any reference book/material about the white face? I would like to know more about the transition due to aging. I cannot find any material on internet or books I have.

That was the first time I saw a white-faced moorhen. The white area on the face was so large that it looked quite different from the other moorhens. Furthermore, its size was as large as the other moorhens too. So, it is quite interesting to know when the transition starts.
