Wader mystery revisited

I posted a photo of two small wading birds, photographed at Mungalla Station near Ingham Qld, a fews weeks ago (see Mungalla Station part 2).



In this post, I had assumed the bird on the far left was a Red-necked Stint and wondered what the apparently smaller bird just to its right might be. The sizes can be judged relative to the Sharp-tailed Sandpipers on the right.

Since then, I have re-examined the original images and run them past a few colleagues and the longer we look at them the less sure we are.

The main problem is that the legs are not black. I initially passed this off as due to mud but closer examination makes this questionable. The legs appear to be a dull yellow. As you can see from the image above, the late afternoon light gives an exaggerated yellow in the photograph so I went back to the original raw files and neutralised the colour-balance. Here are the only 4 images I took of these two birds with no other manipulation (apart from colour balance neutralised).

And here's the "smaller" bird by itself taken just a few minutes before the sequence above.


So, any suggestions for what species they may be?

Update 25 Nov:
Thanks to all those who emailed me on this. Consensus of opinion is that the two birds are Red-necked Stints, most likely first year birds with worn plumage (it's a long way from Siberia your first time!)
