Paolo Taranto, who supervises the nest at the Fair in Bologna, went to the nest site today to fix the cams and install a microphone. As the peregrines are still incubating he was able to get a good look at the female and also take a photo of her. He is reasonably certain that it's Aisha, half of the historic pair at the Fair. See http://www.birdcam.it/forum/viewtopic.php?t=4797
for his photo.
As you'll know from this topic, we thought that we'd lost both birds but it seems that we've been lucky. Paolo said, "I can't swear 100% (because of the spot that's disappeared) but it's Aisha's voice, her feet, the colours, the marking, the moustache and the pattern of the nape so I'm personally inclined to think it's her, also because the mark can disappear with the moult, it's just a plumage feature so it's set with age. As far as the donut is concerned,
(Warbler: I raised a doubt about the lack of the 'donut' nest) it's true, it's not the usual nest, this year the eggs are much further back, close to the window, probably due to the colder winter. Her behaviour also seems to confirm that it's Aisha - when I opened the window she neither screamed nor fled immediately but got up very calmly, as though she was used to this, and left. Then, she returned to the nest immediately after less than a minute."
That seems good enough for me. Let's hope that Aisha is able to continue for a few more years
