Thanks for the lovely comments
1) Pair of Whooper Swans coming into land at Martin Mere
2) Whooper Swan having a stretch
3) Mandarin Duck
Lovely images and tack sharp.
It's a pity this site doesn't have the EXIF information displayed for each image so we can look at how the image was taken?
As snowbear says, 'what noise'. I would agree that you can step down to 1/500 and to make the image better i would have cloned out the post and had the swan further to the left to make it a better composition.
