To Castren:
Sorry but there are no photos of this bird. It was far away enough. It was adult bird. The bird was silent but Eglė heard voice of this bird just after it flew away and sayd that voice was not very similar to A. hypoleucos (it was more clear and had maybe more high tone).
The most important moving criterias – this bird never stoped to bob rear body. It stoped just after layed on the sand. The bird was alone in the middle of pond not near the water were another waders used to stay.
The most important plumage criterion – big black spots on breast and sides. One moment I even compared it to the falcon (hobby).

The top was whole-coloured, similar to that sand (grey-cacao) where it layed.
Another criterion very long sharp white supercilium.
The legs were not yellow they were dark grey-cacao colour. Bill was absolutely straight dark enough not yellow, however base was more light.
Tail was rather short. The projection of that bird was not similar such for example wood sandpiper; however it was most similar to green sandpiper. The top of the tail was grey, however the edge of the end was white.
The bird flew away very quicly one time the flying was interrupted as was similar as A. hypoleucos, however it flied high and disappeared.
Just after we saw this bird the first mind was that we had never seen this species before. The first picture that Eglė looked in the guide was the picture of A. macularia, because the first mind was that it is the same bird. There is no another bird with such big black spots as we know.
Bird was observed for about 15 min. with spoting scopes Vixen Geoma ED(20x60) the day was sunny sun was from back so we saw it clear. It was about 100 m away.
One time I tried to take a picture through telescope with my mobile phone. But it is very unclear.
