Yes, I know it well. So much so in fact that I almost recognize the perch that the eagle has chosen. I must be mistaken because recalling a perch among countless perches is just nuts. Still, it does look familiar. I have often seen RT hawks there and perhaps I saw one on that particular perch at some point in time. I can't imagine that you were expecting to see much when you arrived and well, don't that just make your day. I've also seen hawks and a harrier down close to the Beare wetland just down the roadway. Did you head down that road or did you trail it south of the building and past the observation deck? Have not been there is quite some time since I can't go out any more but it's close by and easy to get to. I wish that I could check-out the hill since that land and the accompanying man-made wetland offers enough open real estate to attract plenty of raptors and probably some of the same species often seen at Downsview. Even when I could occasionally head out, Downsview park is just too far away.
