What type of ducks are these?

Some wild ducks have been hanging around my anconas and was wondering what breed they are

Two of them have the same colour markings and one is different so I was thinking that one could be the male?
Will attach a photo

I think maybe Canvas backs. Awesome!

Thank you for your answer but I searched the Internet and found that they are Australian wood ducks
