Normally I send this kind of information only to my co-observers but this bird was so popular that I thought to post it on Birding-Aus, Eremaea and here in order to reach all observers. Earlier today I got an e-mail from Tony Palliser with the following news:

"Submission No 766: American Golden Plover Pluvialis dominica Boat Harbour, NSW. 12th January 2009 to 28th March 2009.
Submitted by: Tun Pin Ong, Nikolas Haass, Graham Buchan and David Stowe.
Verdict: Accepted.
...
This is the 3rd confirmed record for Australia. The first was a worn and faded juvenile seen and photographed at Byron Bay, NSW on 8 November 1994 (BARC case no. 189) and a well photographed individual at the Dry Creek Saltfields, SA in November 2006 (BARC Case No. 529)."

The full acceptance letter with detailed information on the acceptance process has been uploaded onto the BARC website:

(klick on "Index of Decisions and Case Summaries" and scroll down all the way to #766).

Best wishes,

Nikolas

P.S. Yes, I know that the bird was reported on Birdline NSW as late as 3rd April 2009 and on birding-aus as late as 5th April 2009.
