Mallard ducks

A few days ago I wrote about a recent visit to Peterborough in the mid-north of South Australia. During that visit I spent a short time birding in the Victoria Park, a delightful spot next to the local swimming pool and caravan park. Because of the artificial lake and trees planted in the park there is usually a good range of local birds, including a few water birds in and around the lake.

Included in this range of birds are a few introduced species, notably and large flock of Mallard ducks. I have shown several in today’s photos. In the photo below is a completely white duck, species unknown. If any of my readers can enlighten me I will label it correctly. It is obviously an introduced species, one of many ducks kept in captivity here in Australia. The closest I can come to a name is Pekin Duck. Any ideas, please?
