Problems with ID

The conclusion is that this is in fact a little stint - probably a ssp that we are not used to

---------------------------------------
Seen near Dur on the eastern shore of Bahrain in a small wadi being used to dump semi treated water - (smells a lot but the birds like it) as always when you get a problematic bird its always too far or badly placed in respect to the sun to get a good photo; this bird was both - just didn't look right for the usual little stint as seen around such pools - have ruled out the bigger sandpiper and Temmicks which it certainly isn't. The camera can lie but looking at the pics am at odds to possitively identify the bird.
THE PROBLEM BIRD

JUST FOR REFERENCE our normal model - Little Stint

same Little stint as above but keeping company with a Kentish
