There are three Wedgetail eagle siblings, young ones, about a year old, who hang around the tower. Their colours are bright and lustrous. They are a tawny shock at the other end of the scope and I will scramble down the ladder to get out on the rock with them. This one, Aquila I call her, often flies with her landing gear down. Her talons aren't stretched out ready to attack; she just floats on the updraft, hanging her legs. When she spots something her speed and ferocity is thrilling.
