Golden or American Golden (1 Viewer)

Up the boro!
This juv plover just showed up today outside of Banagher, Co. Offaly. I can't give it a firm id, what do you folks think? it was fairly confiding and on it's own.

cheers

Hmm, I'm not sure this is a juvenile first of all. It seems to show quite a mixture of fresh and worn feathers on the upperparts. I'm finding it hard to call it as anything other than European Golden - it looks rather short legged and the primary projection and tertial length seems okay. I'd expect an adult American Golden at this time of the year to have a lot of black on the underparts but a lot of European Goldens have already lost theirs.
 
looks like a 1st-summer American to me, extremely long winged even taking into account the worn tertials although they look like they once had big pale notches like American.

I think I'd tend towards AGP for this. Dark plumage, prominant supercilium and long primary projection all seem to fit.

Doesn't seem massively long legged though... depends how long the grass is, spose.

I'd also go for American Golden Plover, but it has been a long time since I saw one. I can tell you it definitely isn't a Pacific Golden Plover.

For all the reasons already mentioned- long primaries, prominent super, greyish plumage and the tertial pattern I'd say American. Seems a little ittle slimmer and less bulky than Eurasian Golden. Also seems quite small-billed and longer-bodied than the other two species. Not sure long legs is always an American trait, though certainly is for Pacific.

I think if I saw this I'd be looking at it hard to see what its underwing coverts looked like, but I'd be a little surprised if they are were grey. Its an adult. I'm having trouble making out the tertials - I think its dropped at least one, and I certainly can't see the coarse notching I'd expect on AGP. Adult EGP have corking supercilia in Summer plumage.

I think I'm with Andrew!

Below is an adult American Golden Plover I saw in Lewis in early September last year. Even at that stage, it retained a great deal more of its breeding plumage than the Irish bird shows. On the other hand, I saw around 50 European Golden Plovers on Sunday and most had already lost their black underparts. The Irish bird seems to have retained its summer head pattern to some extent, which is much more contrasting and AGP like. But I can't see this as anything other than a fairly normal moulting adult European Golden Plover.

but 1st-summer American shows little or no black below. I know Eurasian can show variable wing length but I've never seen one with wings like this and all other observable features fit American very well IMHO. Would be interested to see any pics of July Eurasian that match this bird, i.e. strong contrast between upperparts and underparts (including upperparts with some plain brown feathers), diffusely grey-barred flanks etc.

Hi Andrew.

Can we really use the state of the birds moult from summer to winter plumage reliably? I mean, they're all going to be different; some with near summer plumage, some with near winter, and some with a mix. Also, aren't induvidual birds going to vary?

Also, would a EGP ever have this much black and this little gold in the plumage?

I don't think you could use this 100% reliably but it's a very useful guide. I think it would be a very atypical for an adult AGP to look like this at this time of the year. I would expect that most, if not all, would be more-or-less in full breeding plumage. EGP on the other hand would quite typically have lost most of its breeding plumage.

I'm not sure what you mean by 'this much black' - it doesn't look to have very much. And compare with my picture of an AGP. As you say, birds vary and EGPs vary in plumage tone a great deal. Quite grey looking birds are not unusual. This bird also shows a somewhat thicker bill than the AGP in my picture.

I can't see anything much in favour of this being an AGP.
 
OK. Shant take this any further; you seem to know what your talking about, lol! I've only seen one AGP, and was with a very good birder so I think I learned alot. However, theres still much more to understand, as this shows. Also, I reckon I've forgotten most of what he told me!

Jason
 
thank you all very much for your thoughts. i have a few other very bad shots i can post if you wish - on one of them a wing is raised and it does appear to be white under there. ill let you know what other people think round here if they see it. thanks again

Don't worry Jason - I've not seen a huge number of AGPs myself. I know that there are a lot of pitfalls for IDing one, some of which I've fallen for myself. One is that European GPs sometimes retain the contrasting head pattern, with a whitish supercillium and dark crown, after they've lost much of the rest of their breeding plumage. I think that's what's happening with this bird.

would like to see the underwing shot Jaimie!

here's a ref for 1st-s American, albeit earlier in the season:

really dodgy photos - but thought they might help clear this up. one of it feeding, to give a better idea of shape, and the only shot i got of it with wings raised - sorry! he only did this once in the hour and a half i watched it.

The white on the underwing in the later picsdoes give it away but...given the amount of wear much of the plumage and limited breeding plumage feathers, I wouldn't be surprised if this isn't a 1st summer rather than ad EGP - I've seen birds like this before.

Moult can be quite useful in picking up ad AGP amongst EGP as AGP is a long-distance migrant which tends to moult mostly once it reaches the wintering grounds, therefore ad vagrants in the UK often have much more bredding plumage than the EGPs they often associate with. EGP moults right through from July to Oct, so although you can still get odd ones later in the autumn in breeding plumage the majority are well moulted.

Cheers,
Andrew
