Thanks for ID help, Ginger. Today there's a different peregrine who perched on a dead limb for several hours, then flew to the ledge. Could it be Zooey?? At the same time, near 1:00, Newman (I think) was sitting on the nest cam apparatus, looking intently at the other bird. From camera panning, you can tell it is not the same bird moving from ledge to next box. But it was the same bird flying from branch to ledge.
