Yes, this bird is unusually pale.
It doesn't look quite as pale as the bird photographed at Mai Po last year (http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1). I don't know whether it may be the same bird in adult plumage, or if not whether it's related somehow. Author: Bandrew Time: 30/08/2017 20:13
Thanks for the information. I hadn't seen those pictures before so it was interesting to compare them.
I think the bird I saw was not as light as that and was more of a cream to light sandy brown. As you say it could be the same bird as Mai Po but in adult plumage. Still very impressive in the sunlight!
