Hi Greg,
I counted 150 Nankeen Night Herons (67%) in June camped in Coolabahs on Marra
Creek, (Tributary of the Bogan River), Williewarina Station (North of Nyngan)
NSW in June. I reckon there might be hundreds of such events in western NSW
this season.

Subject: A siege of Nankeen Night- Herons, Yanco, NSW
Over the years I have seen the odd Nankeen Night-Heron up and down Oz but
usually alone and skulking along a river bank. Yesterday we saw a "siege"
(collective noun for herons, according to Wiki) of NNHs.
At Yanco just south of Leeton, NSW there is a weir on the Murrumbidgee. In
dry seasons it's a dam to feed water into the MIA but now it's a weir and
feeds overflow into a loop of the river. At about 3.30 pm a pair of NNH's
flew into a tree about 200m downstream from the weir. By the time we left
half an hour later we counted up to 100 birds had arrived at the roost and
more were arriving every minute. About one third were juveniles and
conditions in this neck of the woods are excellent at the moment.
I know herons are colonial birds but is this odd or are there large Nankeen
Night-Heron roosts up and down the inland rivers?
