This odd-looking bird is a Noisy Friar-bird. Friar because of the hood? If so, this friar has a very messy white clerical collar.
I have lots of them here but have never been able to catch them with the camera, as they move very quickly and seldom stay still for long.
But the days are hot and the bird bath is tempting. This one allowed a wattlebird to have a brief drink at the same time and then harangued it loudly, beak open and red eye sparking, until it left.
These birds more frequently drink at my dam, as I described in The Woman on the Mountain:
My small dam in front of the house is a great meeting place — hanging out at the local pool. As always when different gangs meet, there’s a lot of showing off, like the wattlebirds daredevil-diving from a high branch to skim the water and up to a tree on the other side. I sometimes see strangers, such as a lone cormorant or heron, stop by for a drink or a swim. Wood ducks from my big dam try too, but the magpies hustle them on their way, protesting, quacking and flapping.
Some of the get-togethers down there sound like unsupervised group therapy. The weird friar-birds, with their bald black heads and knobby beaks, have a scale of maniacal cackles straight out of bedlam, and over the top of them loudly boast the wattlebirds, ‘I got the lot, the lot, the lot!’ The racket goes on and on, up and down, back and forth, apparently reaching no satisfactory conclusion — a bit like parliament on one of its less than statesman-like days.
