Actually, last Friday could have been called Black Cockatoo Friday, as I was lucky enough to encounter another* flock's sortie into suburbia. I watched (in pedestrian awe) a dozen or so glide around the creek, making crows look like sparrows in their wake.
Googling led to this illustrated post.

I loved the recent post: In Praise of Trees
but the most recent posts liveblog the floods.
