19/12/04  I saw a black falcon here at
  Wilmington SA, near Pt Augusta this morning.  I have lived here seven
  years and  haven't seen one here before, but I think I probably have
  missed them.  The only reason I saw this one was Phillip Maher's comment
  to notice the quick, flickering wingbeats.  These were very obvious and
  were what drew my attention to the bird.  Other things which stood out
  were very pointed wings, and pointed elbows of wings and long tail.  the
  bird also had slight black marks at end of underside of wings.
   
  Wally Klau a local birdo has seen them here
  before so I suspect I will see them more often now I have my eye in. 
  Black falcon was a bird that I saw for the first time on a trip with Philip
  Maher and it had been a bird that I should have seen, but hadn't.  It may
  well be that I had seen quite a few adn just didn't know it.
