Ducks in flight (1 Viewer)

[Atomsplitter]

Having a hard time identifying from these flight pictures. I do better when they are sitting and closer to me. All the same flock of waterfowl. Just different lighting conditions from the morning sun. Photos taken 10/6/23 in Indiana.
Thanks.

First two shots, the birds look to have a white speculum so Gadwall?

Second lot look like Wigeon?

I'm so out of practice with UK birds!
