Interesting. I had the privilege of one of these in my garden in Canberra in July & August 2007. It was only the second ever record in the ACT (the first was at Jerrabomberra wetlands a few weeks earlier). It was seen by me everyday for nine weeks and something like 60 people came to see it. Lots of photos taken by many people and I and other have hours of video taken of it. It was astonishingly reliable and generally the longest daytime period that anyone had to wait to see it was about 20 minutes but usually less than one minute. As far as I know of the 60 or so people who came (some from far away) to see it, only one person missed out.
