There have been no further sightings of peregrines on the camera monitoring activity on the nesting tray. The female is often to be seen on the tower, but she seems to be on her own.
On the top of the tower in the lead chutes that are used as a "dining table", there are often some prey remains, and last Sunday morning there was one carcass which I think was a common gull.
What was I doing on the top of the tower?
Untangling the flag!
