Need confirmation but we think that this is a Green sandpiper – seen this morning at the Darvill Sewerage Works outside Pietermaritzburg. Note the prominent eye-ring with no supercillium behind the eye (not a Wood Sandpiper); the barring on its tail; the lack of a white shoulder patch (thus not a Common Sandpiper); the dark back with white speckling faintly visible. When it took off the rump only was white (not up the back) and there was distinct barring on the end of its tail.
