CLOSED: Duck ID

Can't find these ducks in my Bird book. Anybody able to ID them?

I was thinking Black-bellied Whistling Ducks but I'm not 100 %.

Agree with Black-bellied Whistling Duck's, the white wing patch is noted in my field guide while their in flight.

Thanks, Pelle and Burd.

here's a close up for you

Thanks, Donna.
