Duck Identification

Hi all, I volunteer for a wildlife rescue beased in Kent. We are struggling to identify 2 ducks (?) that we have in our care. Can anyone help identify the species? 

Thank you

  • With the blue speculum feathers I would suggest it is mallard.in origin and may have interbred with domestic white ducks to give the white fleck/brown plumage. Maybe others can verify.

    Well done for all your volunteering efforts. Hope the ducks recover.

    Thank you for your reply.
    We thought mallard but they are a lot bigger than usual mallards, as you said there may have been some cross-breeding. We have had all sorts of birds passing through and have never seen these before.
