How long will Pigott hang around her territory without some male showing up? I'm trying not to worry about her moving into Beauty's territory, but I'm thinking that if she doesn't get a mate soon, that's what might happen. Could DC still show up?
Also, could her chosen nesting site be a possible deterent for passing tiercels?
I can't answer all your questions but migration is still going on and there is a possibility that DC could be late. Don't forget, last year he showed up the 1st week in April. If he doesn't, a passer-by may stop in for some company with Pigott. As far as the location at BS, many falcons have been spotted there in the past, so it's a pretty active site. In Rochester, anything can happen. If DC does not come back, I hope she finds herself a mate also. She deserves it.
