Hi Geoff
Did you see this bird emerge from under the boat?
On this pic the wings look as if they have some rufous on them, which I'm pretty sure Striated never shows. It las looks like the wings/tail have blackish feathers, but I guess it could just be a trick of the light.
When you add the cmment about scalloping It gives weight to my gut reaction that this is a juvenile Black Bittern, but acknoledgign it ahrd to judge size from this pic I wouldn't yet rule out Cinnamon, with those rufous wing feathers
Cheers
Mike K
