Re: Golden-Plover Species, South Carolina, USA 7/4/09Hello, folks. A second photograph of the unknown Golden-Plover in South
Carolina, USA on 4 July 2009 has been added at the link below: http://www.carolinabirdclub.org/gallery/amgp_giduz.html I have not received as much feedback so far as I might have hoped, but I also acknowledge that the photos taken by the observer are not terribly good for such a difficult identification. I have been pointed towards Pacific Golden-Plover by a few experts, both on this ListServ and via personal emails. But of course, I recognize the possibility that a 100% certain ID may not be possible given the photos. If more become available I will keep this group informed.

Re: Golden-Plover Species, South Carolina, USA 7/4/09It would be interesting to read the opinions of those who wrote privately so
that we can all learn from their arguments. This bird is a wonderfull example of confusing all camps. Lee points at the rather long tibia which may favour PAGOPL. AMGOPL however has tibia that vary in length some of which seem to overlap with PAGOPL as in my opinion is the case with this bird. The long wings extending clearly passed the tail favours AMGOPL since the wingtips of PAGOPL barely exceed the tip of the tail. So my vote goes to AMGOPL probably a female.

Re: Golden-Plover Species, South Carolina, USA 7/4/09Ken,
On an initial glance, I don't see too much wrong for American Golden Plover, so I would respectfully disagree with Lee's comments about the bird being a Pacific..or maybe I'm just not seeing it. The overall shape looks OK for AGPL and there seems to be rather a lot of whitish-tipped feathers on the upperparts and wings and the wingpoint looks long and extends past the tail quite a bit. I often have an impossible time trying to use bill length as an indicator. Again, tough from one image. The second question would be to age the bird...are we sure it's an adult? Could it be a 2nd cal-year bird? The wingtips look long, too long for a Pacific but it's hard to judge the wear - they don't look too frayed and warn, but appear brownish. American Golden Plovers molt into breeding plumage later than Pacifics (May), so one would expect AGPL in July to be rather crisp and stunning, whereas Pacifics attain breeding plumage earlier and so by late summer would be more worn. The bird is rather tatty for an American Golden Plover in July, but maybe it's due to poor health or just a bird in advanced plumage. Maybe Kevin Karlson, or Peter Pyle could add something relevant on molt of this bird since that may hold a clue to it's identity? best, Julian Hough, CT, USA jrhough1@... www.naturescapeimages.net ----- Original Message ----- From: "Ken Blankenship" <kenhblankenship@...> To: <BIRDWG01@...> Sent: Thursday, October 22, 2009 6:32 PM Subject: Re: [BIRDWG01] Golden-Plover Species, South Carolina, USA 7/4/09 Hello, folks.

At this risk of agreeing with Lee again, I think the bird is probably a Pacific. Looking in 'Tundra Plovers' it says "projected backwards, the bill reaches well beyond the eye in Pacific, but barely across the eye in American.....". Commencing body moult in early July would also be fine for Pacific, but outside the typical range for adult and 2nd cal year American.
Cheers,
