Dear Tun Pin Ong,
I haven't spent much time looking at your earlier photos (I don't
subscribe to birding-aus) and not terribly interested in vagrant birds
and don't go out of my way to chase them.
However I have looked at a number of your photos this time and have no
doubt that the bird you have photographed is an American Golden
Plover. I last saw this species in 1994 in northern NSW, the only
record accepted for NSW (another observer submitted the record, not
me). The AGP has an obvious difference from the PGP in its jiz, as
obvious as the difference between Wandering and Grey-tailed Tattlers.
An interesting comparison between the two species is that Wandering
Tattlers often have a late moult of the primaries (when compared with
Grey-tailed Tattlers). This often attracts attention to the North
American bird, apart from the obvious difference in colour and jiz.
However, returning to American Golden Plovers, I don't remember the
state of primary moult in the 1994 bird.
It is a pity that it takes the arrival of a vagrant before people
start taking a close look at our common birds, to compare plumages. I,
and other members of the AWSG, are interested in obtaining good, high
resolution, photos of any of our shorebirds through the year for the
purpose of aging and sexing birds in the field. We have aged a lot of
birds in the hand from close examination of plumage. However with the
improved technology of digital photography we can now see finer
details of birds in the field. If anyone has a good series of high
resolution photos of any of our shorebirds I would love to have a CD/
DVD of them (obviously not doing anything with them without the
approval and acknowledgement of the photographer).
Keep up the good work
Cheers,
