report of probable "cox's sandpiper" at Edenhope, SW Victoria

Dale Tonkinson tells me that saw what he considers was probably a "Cox's Sandpiper" at Lake Wallace in Edenhope, south-western Victoria, at 1800 hrs on saturday 5 March.  It was feeding on southern shore of the lake, and was often harried by Sharp-tailed Sandpipers (the only other migratory waders noticed on Dale's short visit).  Its plumage was closer to sharpie than Curlew Sandpiper and the bill length and shape were intermediate: severasl other plumage features were noted.  The bird fed by vertical probing, in the manner of Curlew Sandpiper.  There have been very few records of this hybrid in recent years, so it would be good if this gets confirmed.  Cheers, Richard.
