Robert Gosford queried...
  Are
  there any falcons etc nesting downtown? I seem to remember a thread to this
  effect some time ago and reference was made to Peregrines in Melbourne 
  CBD.
   
  From my vantage
  point on Levels 27 and then 22 of a building on the NW corner of the Sydney
  CBD (where I worked until October last year), I used to regularly see a pair
  of Peregrine and have also reported to NSW Birdline (before I joined this
  forum) White Breasted Sea Eagles passing along the waterways - I overlooked
  Darling Harbour and White Bay and west up the Parramatta River. From my new
  lower perch, also in the CBD, I have seen a Peregrine sitting on the louvres
  that overhang the windows of the Grosvenor House Tower
  block.
   
  Cheers
