No Graham, this isn't the Dry Creek bird. Quite a different site, b..
miles away, and not our bird, which, at last report , is still here.

Keith and all,
I have to disagree that there is nothing to discuss on this bird, or
more specifically on the identification of American Golden Plover. There
are a lot more characters to discuss on the separation of Pacific Golden
Plover from American Golden Plover, like head-shape, bill size, leg
length, primary projection (although there is some overlap, especially
when the bird is moulting, birds out of wing moult, e.g. juveniles in
their first 'winter' plumage are much more straight forward). In fact
I'd say that, at least to my ear and experience, call is one character
which I wouldn't rely on to id a 'Lesser' Golden Plover to species.
Sometimes though, it's a suite of characters that you have to consider,
not just one individual character. I do somewhat agree with Keith
though, that Mick's photo does not show enough features to identify it
as either species. One thing I am confused about - is Mick's photo the
bird at Dry Creek Saltfields, in SA of which there is another, much more
convincing photo here:

Cheers for now,
