In Australia, apparently the magpies have a dislike of hang gliders:
Speaking of bird strikes, that damn falcon that smacked me on the head last year is at it again, he got me on Monday. The building owner is applying for a permit to get the hawk trapped and moved somewhere else.
Maybe he was circling above a mother's nest? They get protective (understandably).
Did I see the bird fly formation a few seconds later? That was cool.
And the glider pilot is now current with 3 touch-n-gos.
