The nesting tray has been serviced, closing up the gap between the planks, and a layer of new gravel has been provided.
All we need now is a pair of peregrines. I did see Bella on the tower twice last week (but too dark to photograph), but Christopher Robin hasn't been seen since September. This is nothing unusual as he was not to be seen at this season in previous years.
I don't know what bird has triggered the camera - all you can see is his tail and feet!
(It does look rather like the rare BLACK REDSTART we saw last year)
