Good post Carly. I've always said that Urban Peregrine Watchers know more about the behavior of Urban Peregrines than the "experts".
They say that only Tiercels will battle Tiercels and the Falcon (females) will fight each other. How many times did we witness Kaver driving off a female? Like you, we've seen many behaviors that go against what the "experts" say.
The year that Gahastey was hurt, Mariah and Kaver allowed her to land and remain on the Kodak Tower late in the season. Havoc (male), the guardian angel of that year, tried to remain and hang out with Gahastey. He would land on one of the RG&E smokestacks, while Gahastey was on the Kodak Tower.
We saw Mariah attempt to chase Havoc out of the area multple times, while she seemed very content to allow Gahastey to remain. I believe they do know when a young one needs extra help.
More about "guardian angels". Every year, one of the young fledglings seems to take on that role, hanging out with siblings that may need extra help. I've noticed that it's usually a Tiercel hanging out with a sister, but not always.
I find studying the behavior of these magnificent creatures fascinating. Can't get enough of watching them. I am not addicted!
Nicole - Please keep us updated on what happens this year at your nest site. It could get very interesting.
