This is probably a daft question, but as a relatively new bird watcher, it still puzzles me. I wanted to show off my new found skills to my brother recently, and took him to my local mere, where I told him I would be able to name all the birds we saw. I was able to do this, apart from this white duck. There is nothing like it in my field guide, yet it is very common, so what is it?
