While I was watching the Little Black Cormorants I realised there was a Great Cormorant perched on a rock overlooking the dam. It was not disturbed by the other cormorants. It initially did not seem to pay any attention to me. I sat down where I was since I did not want to disturb it. That was when the other cormorants flew off. After a while the Great Cormorant also decided to leave. It took off from the rock, initially heading low over the water but rather than flying towards Lake Burley Griffin it banked to the east, circling the dam twice before it finally headed in the direction of the lake.
