I've watched this nest for many years, have visited the site in person and have met one of the locals who keeps a close eye on these peregrines. The male, Lil Dad, is one of the best peregrine parents I have seen anywhere. There is no doubt in my mind that he can handle raising the chicks from here on.
As for the female, NG, my understanding is that someone with CPF observed video and images of her and thought the problem could be Frounce (Trichomoniasis), but cautioned that there are other diseases that mimic Frounce. Others think she may have been injured in a battle with another adult female. She was seen escorting one out of the territory on banding day. (Wanted to submit this info so TPC would be better able to answer the question about prognosis.)
