Male American wigeon in TBT

American Wigeon would be a first for Hong Kong, although is a likely visitor here.
There is a slight complication that hybrid wigeon (American x Eurasian) have been reported on several occasions.
For example, see:
http://www.hkbws.org.hk/BBS/view ... &extra=page%3D7
Did you note any features that confirm this as pure American Wigeon? Are there any photos of the bird?

I am not saying your bird isn't American Wigeon - I hope it is! Certainly it will be worth keeping a look out among the wigeon flocks in the coming days.

The picture certainly looks promising for American Wigeon - congratulations!

I recommend everyone should keep a look out for this bird - hopefully more birders/photographers will be able to find the bird and confirm the ID.

This link shows some examples of hybrid wigeons, to show the variation

Key features to check if you see the bird are the exact head pattern, extent of pink on flanks and, if possible, wing pattern (underwing and upperwing)
