Grappige hybride, iets van Carolina eend x Kuifeend of zo? Gokje uit de losse pols...
Andere opties uit dezelfde pols....
Carolina x tafel
of iets met krooneend

Alcedo atthis

Carolina eend x Aythya sp. , may well be Kuifeend. (But I am wondering about the relative darkness of flanks?)

Not x Krooneend, wrong bill colour .

I was also wondering about that. That´s why I thought of Tafeleend as an option instead of Kuifeend. But the flanks of Tafeleend aren´t that dark either....

 a hybrid with Taffeland would have the scapulars paler and with a vermiculated pattern.

I think the Aythya involved must be one with black scapulars... if that is right we would have to choose between ringnecked duck, tufted duck and New zealand scaup. maybe there are  a few more options but i would tend to exclude hardhead , baers pochard and ferrugineous duck?!

And Rosybill (Netta peposaca ) is out , as that would have a more swollen bill basis...

The grey parts look like a male Gadwall ....
