Shoveler's shoveling.

Interesting behavior to watch as they do a circling pattern together to feed.

Both ducks are sharp and nice eye contact. the male whites look like they were overexposed and then recovered in post?
I like that you have eye contact for both, you got a nice low angle too. IMO this image would be stronger with both ducks and their heads parallel to the back of the camera.

Very intimate photo of the birds vortexing. I'm actually trying for a similar photo with one of our Aussie ducks that use the same behaviour to stir up the tidbits.

I agree with Arash's comments regarding the whites.

I like how you can see the eyes of both birds. White in the under-tail look as if you have cloned some grey on them.

Like both eye looking at us! Might consider a bit CW rotation and pano crop.
