The male here definitely has a black band on his right leg, couldn't see numbers. Rose got new binoculars and they work pretty good. We did see both falcons go into nest box and we heard them chupping.(sweet nuthins)
He flew away and she did a lot of furniture moving for about five minutes, then she left and he went and rearranged whatever she did.
We wondered where she went because she flew to north side of building, so went down to the street trying to see if she was on north light. Nope, not there. I did finally spot her, she was on a window ledge in between the two connecting buildings about seven stories up.
