Pacific Black Duck, and more

At the same location as the previous White-faced Grey Herons, post.

A couple of ducks had been swimming about in the distance, and then had chosen to paddle between the rocks and find their way to another part of the river, further upstream.  This one is the Pacific Black Duck; with a difference. Seems it's a 'ring-in" - explained further, in Christian's comment.

can't be sure if male or female, so off 'it' goes now in the section where the leaves and litter gets choked up before the filtering concrete baffles you saw last post

and up pops this one looking out for it; hardly a pair, but they definately were sticking together as a team.  When looking at the photos here I noted the green bands on this one.  Is it a Muscovy? Later addition: Having since checked Google/Images on Muscovy ducks, it seems not.

..now I really want to know what kind of duck it is, though it's sure to be another hybridised version I guess

When this one caught up, the two  swam off together,

in the cleaner waters, where a Dusky Moorhen was also enjoying the late afternoon sun.

Much later notation added: Great info' from Alan Morris "The duck with the tags is a domestic duck so some person has put a plastic tag on it as are available for ringing poultry etc. As a domestic duck it does not have to be crossed with a  Pacific Black Duck although it would be a Mallard deriritive, possibly related to those white Peking Ducks which are descended from Mallards.."
