I really appreciate all the help this forum is. The foreign ducks are not easy as I do not have the resource material to check, and don't quite know where to begin on the net, so would appreciate help with this final photos.
The photos between these two links are the last of the foreign birds I have photos from which I took in July when we visited Slimbridge. There are five photos following the domesticated geese.
One of the ducks were in the tropical house. The two smaller brown speckled ones.
