Welcome aboard DJ, and great news to hear that you are getting what sounds like some visits from the peregrines! Just a couple of things ... the nestledge you mentionned in your post and "the" nestledge are in fact two different locations on the Radisson - you can see the west-side nestbox, the east side nestledge is unfortunately out of view to you from your fine perch at IG at Portage & Colony. Didn't want you to get confused when the gang here talk about the nestbox and the nestledge!
Aha! Good to know, I am new to this after all, and while I am familiar with peregrines and raptors in general, I only have a small amount of specific knowledge relating to the Radisson's penthouse occupants. I did think it strange that the webcam seemed to show a different location from what I can see from the window here, so that explains it.
Any chance I could get a look at the photo and the story? Since the birds have visited it would be nice to a) make sure y'all have the most up-to-date information on our famous pair and b) perhaps I can tell you who came to visit ...
I had actually intended to do that - actually, I will go and see Corporate Communications, and check whether I can get authorization to send you a copy of the story, as well as see whether there is a high-resolution photo, as all I have is the one from the story, which is quite small and uninspiring.
Sorry to be a pooper but I'm afraid your colleague is incorrect in this case DJ, there have never been any peregrines nesting at the IG building downtown. I've run the project for longer than the IG building has been standing and they have enjoyed visiting but have never stayed to nest.
I see! I just emailed her, to see whether I can get more information on this nest, and her reply was less detailed than I had been inclined to expect - perhaps she was caught up in the 'falcon fever' of the initial sightings here, and was somewhat mistaken. I will check and see if there is anyone else still with the company who may have more information, as it was in 2001 or 2002. It does seem that there was a nest of predatory birds of some sort on our 18th floor ledges somewhere, however.
