Both peregrines are around, which at this time of year is a really good sign for next year's breeding season.
Here is a clip of the female Bellatrix landing on the nesting tray, calling to the male CR who is out of sight to the camera.
The reason there isn't any gravel in the tray is that we are (hopefully) going to replace it before the breeding season gets under way. If it doesn't happen this year, then it will definitely happen next!
This is going to cost around £500 in total. Details of how to contribute will be published shortly. Watch this space!
