Well I'd have to say in reply that the bill isn't yellow - it has an red/orangish base to the lower mandible which is a feature of breeding WR. The leg coloration isn't yellow either - I imagine is just slightly brighter due to the light.

I would agree with Streatham; odd reflectance off the legs, but still a White-rumped Sandpiper. Long primaries, extending well past tail, some chevrons in the side streaking; streaking on a pretty whitish base color. Good jizz, bill for WRSA.
CHEERS, JOE G
I tried hard but I really couldn't make this bird a White-rumped Sandpiper 
For me it's more like a 1st summer Pectoral Sandpiper (possibly a female) :
- heavily worn grey coverts and tertials are indicative of 1st summer
- legs are pale (even if pale legged White-rumped Sandpiper exist)
- tibia is really too long for White-rumped Sandpiper but is fine for Pectoral Sandpiper this makes a shape quite unusual for a White-rumped Sandpiper (but ok for Pectoral Sandpiper)
- bill is too long with wrong shape and too pale for White-rumped Sandpiper but is fine for Pectoral Sandpiper
- primary projection is very long but tertials are worn (there is one tertial missing on left wing ??).
- breast is not well streaked for a Pectoral Sandpiper but that's would be ok for 1st summer bird which "forgot" to moult (or just a poorly marked female).
This is my analysis, in my humble opinion, the bird is a Pectoral Sandpiper.
(A possible female because of smaller bill and lighter breast)

White-rumped for me.

First I thought to my self, is Th_SQ the only sensible person on this Tread Because first summer female Pectoral was my emediate impression. But the long wings, jizz, especially in pic.2, and lower scapular pattern had me change to WRS. It does look long-legged and with greenish legs, which is not such a big deal, greenish legs I mean, though I have seen WRS with similar long-legged appearance! There are a slight tendency to chevrons on the flank, and obvious streaks on rear flank as well, good for WRS, but shared with many PS. Looking at pic.3 and the lower scapulars, they would be a perfect match for WRS. On each feather there´s an obvious pale base, quite typicall for WRS and to my knowledge, not seen in such an extent in PS.
So I think WRS on this one.
Have a look at this one, just to compare bill pattern, to mention one similarity:

It is worth pointing out too that JanJ's White-rumped example also shows the pale legs featured on the mystery bird, as well as the bill coloration. I agree that it is a White-rumped, though perhaps the posture shown in the photo (i.e., upright and alert) imparts a somewhat Pectoral Sandpiper feel that we've all noticed.

Never seem a a pec look like that plumage-wise but am willing to believe its possible. What about the structure... leg length, bill shape, body shape......? WRS always look low, horizontal and "cringy/creepy" to me - having remarkably little height from ground to the top of back. Unless its just bad luck that the three pics show it upright and perky looking. Also curious as to how it can have flecking on sides of the rump just above the tail feathers.
How was it in the field, did it move like a WRS or a Pec?

Hi All.
Here is my measured reply.
1) Pectoral basically has no wing projection so that should rule out Pectoral.
2) Pectoral's paelr base to the bill is on upper and lower mandible and extends slightly further on the upper than the lower. Here it seems only to be confined to the lower mandible, also ruling out Pectoral.
3) Pectoral has a notable downcurved bill - not seen on this bird.
4) The pale tips to scapulars leave a clear line down the back on Pectoral - also not ssen here.
5) Juv White-rumped has bright rufous and buff edges to upperparts and a contrastingly pale hind-neck - seems ok for this bird.
6) WRS has bill black with base of lower mandible tinged greenish or yellowish-brown - Ok for this bird
7) WRS has black legs that can be sometimes fintly tinged greenish.- Depends on the photo colour tone etc but may explain the non-blak legs.
8) Shorebirds does state that the uppertail in some plumages of WRS may be lightly marked brownish or greyish - May explian some of the markings that seem to be seen on some shots of this bird.
9) Assume this was taken today, looking at the feather wear etc. Firstly there is no greyish suffusion on the breast so it is not juvenile. That would mean it is not juv yet it has the juv paler hind neck. The coverts seem fairly well worn and look alot more like winter plumage but there are breeding plumage feather comming through strongly on the mantle. Might this not then be a first summer Adult bird with some traces of the juv plumage not yet moulted out? (I think I can see a few greyish spots on the breast which would be traces of the juv suffused grey on the streaked breast). That might explain non-standard feather patterns some people have referred to?
10) If shorebirds pics are very very accurate, WRS shows a more collared effect at the top of the streaked breast which is seenhere and is not equally represented in Pectoral Sandpiper.
I would say White-rumped Sandpiper.
Cheers.
Doug.

also at first glance thought Pec but WRS for me also on most of the above ... primary projection alone would rule out Pec
