Thanks for the update Bev - I got the call from Edmonton while I was out and couldn't manage to talk myself onto a computer to post the info
Given that I wasn't there, here are a couple of comments on today's activities ...
1. Catching Radisson - not surprised that didn't go well, Manitoba birds with two exceptions are wickedly difficult to get near ... Trey and Madame are the only two birds I have ever managed to get within two feet of ... And she was hatched/fledged on the nestledge so her only contact with humans has been banding whereas the vast majority of our Radisson birds are used to the sound and presence of humans on "their" rooftop as Hotel staff have work to do there daily. They don't get near the nestbox, but the old box had lots of openings so they watched humans all the time. Nestledge chicks are different, very miffed at human presence, much more than nestbox chicks.
2. The Chick as Bait - I can guarantee that the chick was fine, just in unfamiliar surroundings. And with the Edmonton staff "hiding", she wouldn't have been stressed much by their presence. Because she could see/talk to Radisson (and vice versa) her stress level was probably no more than during banding.
3. The Edmonton staff - the folks in Edmonton are among the best in North America so at no time was the chick or Radisson or the adult male (he was around without a doubt) in any danger and they would have never have done anything that would have been overly stressful for any of the birds. The fact that Radisson hung out on the front of the nestbox was/is an indication that she wasn't overly concerned. If she were, she'd have been on the wing protecting her chick - when we band the Brandon birds, the adults are flying constantly over/at us and they don't rest until we are long gone from the roof - and we are actively doing things to their chicks - the Edmonton chick wasn't having anything "active" done to her and there were no humans visible so Radisson and her mate were probably concerned she wasn't where left her, but she is old enough to be on her own and they could certainly protect/feed her so new location but not in danger and needing protection.
4. If they had managed to get the transmitter on Radisson, it would have been useful to be able to monitor her movements given the battles they have had over this nestsite in the last few years. Would have been possible to know if the two females - Radisson and Homeless were in the same territory and if there was the potential for conflict ... Also helpful for tracking them down if there is a problem ...
