The chicks aren't one subspecies or another, they are all of them. When the populations crashed, they (in the US) scooped up all the birds they could get their hands on and put them in a breeding program. Most the birds migrate as per anatums, though some with more Scots/Spanish won't migrate much or at all. Madame, the previous Radisson female, had Scots/Spanish in her (she was from Cedar Rapids, Iowa) and she didn't migrate from the time she arrived in Dec 1990 until she disappeared in 2004.
The Peregrine Chick:
They are just about finished the banding and out on the ledge both the adults are patiently waiting in front of the nestbox. The rain has stopped so the image is great. One advantage of taking the chicks out of hearing/viewing range of the adults is that the adults are stressed more by the sound of their chicks calling out. We won't have that luxury I'm afraid, so we will be limiting our time on the ledge instead.

The Peregrine Chick:
The blood is for genetic testing by the Raptor Centre at the University of Minnesota. Its to monitor the genetic diversity of the population since in the US all the wild birds are reintroduced and they are a mix of subspecies - anatum, tundrius, pealei, peregrinus (Scots) and brookei (Spanish).
Falconista:
Tracy, any thoughts as to why they are taking blood from the chicks and what they hope to learn by doing so?
