The Peregrine Chick:
Hmmm, just looking at these new rules the following comes to mind ...
* up to two peregrine falcons per selected falconer - okay need a permit to be "selected", and up to two might help ensure that a nest isn't completely emptied
* nestling or juvenile wild peregrines - nestlings is easy, but what qualifies a juvenile peregrine? If based on plumage, by May many (if not most) young peregrines look like adults so juveniles could mean fledglings of the year in this case or 1+ year old birds that look like juveniles, but that would require trapping which needs experience
* open seasons from 2013-15 - choosing an only three year period could give enough data on how it impacts wild populations
* May 1 to Aug 31 - would mean most birds would have to be from within the state as most (but not all) young of the year from elsewhere haven't started migration yet though they can wander a long way in the lead up to migration
Will be interesting to see if they report the results of these rules as well as announcing the start of them.
Nice find RCF!

Idaho sets rules for falconers to take wild peregrines
Idaho will allow up to two peregrine falcons a year to be taken from the wild by selected falconers under rules adopted by the state Fish and Game Commission Tuesday. Rules allow the take of nestling or juvenile wild peregrine falcons during open seasons from 2013 through 2015. The capture season runs May 1-Aug. 31.

The male has already accepted a new female, who is unbanded and they have been observed bonding. The male is a Canadian bird from the Niagara Falls site, his name is Yankee (black/black 42/Y).
Yankee was one of four chicks hatched at a nest site in the Niagara Gorge in 2008 to an unbanded male and an unidentified female.

The nest is 13-story-high on the MacKay Heating Plant tower at the UB campus.

--- Quote from: Kinderchick on March 16, 2013, 13:14 ---As well, I don't understand the assertion that "this type of behaviour is unprecedented" among peregrine falcons. Is this not the typical behaviour of a female peregrine falcon protecting her offspring? ???

There is aggressive defense and there is aggressive offense. I don't know much about BB but it could be that she was the latter and not the former. Do we know how high her nestsite was above street level? T-Rex was a very aggressive bird but he didn't go after pedestrians - he did go after folks on rooftops but fortunately the site had few visitors to the roof. At the Radisson when there was a lot less equipment on the roof (so early 1990s), the adults used to hit everyone who visited and hotel staff wore hardhats when they had to visit. Nesting 30 storeys about the ground our early Radisson pairs weren't aggressive toward pedestrians, though they did take potshots when workers came out on nearby buildings. If BB's nestsite were higher, it might be that she would have concentrated her "attention" only on the rooftops, but attacking folks at street level is dangerous not only for the pedestrians but also for her - not just pedestrians down at that level, collisions with vehicles would pose a definite risk to her health and by association the health of her chicks.
It would be a tough call to have to make and all I can say is that we haven't had to do something similar yet in Manitoba. Though Jules is coming close and we are having to get very creative ...
