Last month I had reported a Golden Plover at Boat Harbour that has some 
features indicative but not diagnostic of American Golden Plover. 

Yesterday I visited the site again and found that the bird has moulted most of

Pacific Golden Plover. I think the bird will still develop it feathers and 
hopefully its ID will become even more apparent, in this case I think towards 

I have updated my observations in international Bird Forum which requires a 

Also to summarise it and to facilitate viewing the birds in different stages of 
moulting taken from different trips, I have compiled the photos according to 

My first sighting. It still retained the very worn primary

Feel free to comment to further support its ID whether PGP or AGP. Also would 
appreciate whoever visiting Boat Harbour soon for Great Knot or other 
interesting shorebird could help me to keep an eye on this greyer, short-legged 
Golden Plover. This is because I will most unlikely be able to visit the site 
in near future and I would like to see the bird has moulted more convincely 
into a PGP.

Hope this as well as inputs from others will be a learning to those who are 
looking for suspected American Golden Plover in Australia in future.
