Nice, I like the way that the Mallard are flying against the blurred background, but not against any distracting parts. I take it that they were gliding in to land rather than flapping their wings like mad. If they were not, I'd be even more impressed!

Really liking your bird images Mats, what lens are you using
Nice framing Mats,
If I have one small suggestion; it would be that if mine, I would desaturate and reduce contrast on the green bank slightly - not by much - just enough to make the green area on left a similar shade to how it is over on the right hand side.
All the best, Dave
