Egretta novaehollandiae - White faced heron.
I was lucky enough to have this fellow fly over my head and land in a tree, then having got my attention, fly to a pond and begin wading about. Most of the surface was dull at this hour, but there was a sweet spot, so I waited as he did his rounds skulking through the murk and waited for him to pass through the pools of color from the (just turning) autumnal foliage.
