A memorable survey. Common Sandpipers had long been expected, but this seems to be the first time the species has been recorded, in this case near the tug pier on the lower Yarra River. (There is a dead seal nearby on the riverbank.)
The female Musk Duck is also most unusual, although again one would expect this species to be present from time to time. No raptors and few New Holland Honeyeaters sighted, but Black-winged Stilts are back, and nesting, after an absence of some six months.
