News: Peregrines
Kinderchick:
That does seem a bit extreme, as RCF says. >:( To my understanding, BB was only "aggressive" while attempting to protect her newly hatched chicks. The university supported the installation of a nest-box and it seems that BB has been nesting there with Yankee for a few years now. 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? ???
RCF:
AGGRESSIVE PEREGRINE FALCON :o This seems a little extreme in my opinion. ??? ::) >:(
BUFFALO, NY~2013 (U. of B. & Central Terminal)
State wildlife officials have safely captured BB, a female peregrine falcon that had been nesting in MacKay Tower on the South Campus.

Kinderchick:
Thanks for the information, bcbird & TPC. Interesting... Hopefully, if he/she returns to the newsroom ledge, someone will get a photo of a band, if there is one. :)
The Peregrine Chick:

From Wickipedia:
Falco peregrinus pealei, described by Ridgway in 1873, is also known as Peale's Falcon, and includes rudolfi.[36] It is found in the Pacific Northwest of North America, northwards from the Puget Sound along the British Columbia coast (including the Queen Charlotte Islands), along the Gulf of Alaska and the Aleutian Islands to the far eastern Bering Sea coast of Russia,[36] and may also occur on the Kuril Islands and the coasts of Kamchatka. It is non-migratory. It is the largest subspecies, and it looks like an oversized and darker tundrius or like a strongly barred and large anatum. The bill is very wide.[37] Juveniles occasionally have pale crowns. Males weigh 700 to 1,000 grams (1.5–2.2 lb), while females weigh 1,000 to 1,500 grams (2.2–3.3 lb).[26]

Given the geographic location (BC) it is easy to assume that it is a Peale's but the only way to tell for sure is genetic. Size and plumage are the next best ways to make an educated guess - pealei are larger and often darker than anatum. And there are anatum birds from the BC interior observed on Christmas bird counts (Dec & Jan) in southern BC, and very often urban areas along the coast where there is prey. In this case, given how white this bird's breast is, it could very well be one of these anatum birds. Without a scale, no way to tell if this peregrine is larger than an anatum. In fact, this bird could just as easily be a pre-Princess Manitoba anatum bird, in fact with a couple fewer speckles on his/her breast, this bird looks alot like Trey and T-Rex.
Really wish the photographer had managed to get a photo of a band!!
