Also, the Teal is a Gadwall.
The status of Mute Swan in Europe is confused - some argue that they are introduced, others that they are native. Personally, I see no reason that they should not be native (the main problem seems to be that they were farmed and eaten - this also applies to Mallard and Greylag Goose, which are undeniably native to Europe).
PS. The second duck is clearly a Red-crested Pochard, Mike. It looks nothing like a Common or Black Scoter ;-)
