While we still await info from the MNR (hopefully next week), the awesome web of falcon followers has been of great assistance in providing some very interesting info about our visiting adult male.
His name is Jack, he was born in 2002 at Mississauga Executive Center (near Square One), and get this - he's the current mate of the female at the Bloor/Islington nest.
All the help from folks near and far in tracking this info down is very much appreciated. Talk about a soap opera!
