Broadbill Duck and Mystery Duck

Seen these broadbill ducks and this black duck that I never seen before. Does anybody know what type of duck or bird this is?
Thanks
Frank

The first one is a northern shoveler and the last one is a coot (mudhen).

I guess I got both wrong.
Thanks

Nice shots! Yes, Northern Shoveler and a Coot.

This is a real masterpiece! Looks like you like to photograph animals, tell me what camera you use to photograph birds!
