The farm where i used to work near byron had a few wedgetails in the area every other bird flys low and fast when there on the wing , you got so used to the change in behaviour you'd know before you looked up.
They also sometimes attack hang gliders in the area, guy i knew said one once got a good puchase on the the edge of his kite and started tearing it
,, how much fun would that be .
Very majestic huge birds , just recently i saw the local pair lock feet and spiral through the sky together for fun .
