Greater or Lesser Scaup-USA

Attached are several photos of some scaup that were seen on Lake Mendota in Madison, Wisconsin, USA. The photos were taken October 19th of this year.

In the field I ID'd them as Greater Scaup due to head shape. Greaters are unusual for this location (I have only ever seen Lessers there previously). What do you think?

Thanks.

I would say Greater too, as that is a very rounded head.

Thank you all for your input. That is what I thought, but as they are uncommon in WI away from the great lakes, I figured I would check.
