Went down for a quiet couple of hours beside the pond before the chattering groups arrived, and came to the conclusion it should be called the Namadgi Day Care centre. Whichever direction you look there were juveniles. Some feeding themselves (grebes, rufous whistler), others being fed (superb fairy-wrens and magpie larks). As for the grebes, I saw three juveniles and no adults. There were plenty of dog/fox footprints in the mud at the edge of the pond, and the Island is not an island at present. It does not bode well for things that sleep amongst the reeds. The wood ducks and masked lapwings did not stay very long, so I gathered they did not have young to nurture.
Leaden fly catchers and white-throated gerygone were very vocal.
