We had the most unafraid blue-tongued lizard ever visit us just now. It was sunning itself right by the front door, the dog walker came and opened the screen door nearly on top of it and it just didn't care!
We heard a terrible squawking noise out in the back yard, and it turned out to be a pair of Indian myna birds swooping this poor blue-tongued lizard. :( There was blood down the one side of its face, but as far as I could see it was just superficial scratches and nothing major. I managed to shoo out from the open where it disappeared under the fence and into the long grass of the neighbour's lawn and I think the mynas have lost it as this point.
