Nankeen Night Heron

I have not yet identified this bird photographed at the Fishing Boat Harbour early today. It was quite tame enabling me to get up close. (the red background is the hull of a ship)

Some information from my friend and Blipper Roger The Dodger...

"Its a Nanking Heron Bob. A pair used to come and roost on my boat when I lived in the fishing boat harbor. Now all they do is come and eat the fish in my ponds. Beautiful luma"...Thanks Rog

More info - It seems it is a Nankeen Night Heron (Nycticorax caledonicus)
