Jeff,
At the moment, there is an adult? Red-necked Stint in full breeding
plumage in Ballina. First seen on South Ballina Beach on 30th Nov in
full breeding plumage, & possibly the same bird in similar full breeding
plumage was seen last week in North Ck, Ballina. None of the other
R.N.Stints have any obvious signs of breeding plumage, so this bird
really stands out.
Is this reverse breeding plumage? , or is it as you say, a bird that
moulted into full breeding plumage at the normal time in Apr/May, but
then didn't migrate & hasn't moulted since?
Cheers
Steve

"reverse breeding plumage" describes a bird with breeding plumage in the
wintering grounds and I would guess winter plumage on the breeding
grounds,
not that I have ever seen photos of a winter plumaged bird on the
breeding
grounds.
It may well be a myth as the bird at Werribee in 2008 was clearly in
appropriate plumage for that time of year, just wrong location and a
number
of other Australian records also look suitably plumaged for the time of
year. There may well be a scenario where young birds moulting too late
into
their first breeding attire or not gaining appropriate body weight for
the
migration, hang out down south instead of making the arduous flight
north.
As a consequence their plumage remains in good condition and the
pressure
for an austral spring moult into winter plumage could be delayed or even
skipped. I suspect "reverse breeding plumage" could very well be a myth
and
a simplistic answer to something that is actually a little more complex.
Cheers Jeff.

In looking up Little Stint in Pizzey, he states records of little stint
are
"mostly in reverse breeding plumage" I googled this and came up with
nothing.
can anyone shed some light on this?
Thanks Gary
