Hi there it's been several weeks and the Adults & Juveniles in the Kennedy/401 area have seemingly dispersed, I haven't seen them. I think realistically that I'll have to keep a close eye on the area next Spring to try and be.able.to pinpoint the Nest.  Will update.

Since my last post, I have spent some time trying to ID the Male @ our New Nest. Wow is this bird elusive. He's only seen briefly and even then most of the time I'm defeated by Distance or Height to  to read the Band.  Haven't given up yet.  Will continue to update.

Further to the above post.  A new Nest has been discovered approximately 3-4 Km (2-2.5 Miles)West of Yellow Pages site.  It was revealed when CPF received a phone call of a Bird trapped on a Balcony.  This bird turned out to be a Female Juvenile Peregrine Falcon with no bands.  There was also a 2nd juvenile in the vicinity.  The trapped bird  was removed kept over night banded the next day. Of the adults the female has no Bands, but the Male is banded Black over Green. Unfortunately with the extremely Humid Weather we have been experiencing in TO over the last week or so I haven't been able to return to positively ID Male by Band #'s.  However w/the long weekend, and the Humidity breaking I intend to ID the Male. 
.      The  reason I have posted here it is hoped that given the close proximity to the Yellow Pages  site that the male is in fact Reuben. When I'm successful in getting the band #I wil post the Outcome.
