The kestrels returned on 13 April and have visited the nest every day since. It could be several weeks before any eggs are laid. The eggs are usually laid at 3-4 day intervals. It is only after 3-5 eggs are laid the birds will start sitting.
11 May update – four eggs have now been laid – on 3 May, 5 May, 8 May, and 10 May
I made some changes to the window sill nest to enclose it but now regret not having had time to review the layout and new camera positions properly before we went to Letchworth at the end of March. I was doubtful the kestrels would return and did not put a camera outside the nest as I had originally intended (it is still in the box). The cameras are connected to network server in E2E and I can access them remotely.
I now have one camera live streaming feed on YouTube https://www.youtube.com/channel/UCmcJ1sezE3so41txXy4w86w/live The feed occasionally fails and I have to restart it.
Both the female (falcon) and the male (tercel) (easy to identify differences) are visiting the nest more frequently now, especially in the early morning. The camera times are French time (GMT+2)
There is a 2022 kestrels web site with regular updates of daily photographs and videos

Our unexpected kestrel visitors – first update
This is an update to the earlier post here describing the discovery Our unexpected kestrel visitors
The first two eggs hatched on 9 July. Unfortunately one of the first two chicks died.
The third and fourth eggs hatched on 10 July.
There are now two live video feeds and daily videos and photographs on this unexpected kestrel visitors web site
I have added two cameras, a TP-Link Tapo C100 in a box on the window sill and a motorised pan-and-tilt Tapo C200 above the nest. The original Logitech C270 is also above the nest pointing out of the window.
The kestrel seemed very suspicious of the constant red LEDs on the cameras so they have been turned off. I am not using the IR night mode either. The noise of the motors pan-and-tilt control of the Tapo C200 also seriously disturbed the kestrel.
I am feeding the Tapo camera feeds to Agent DVR software to control the timelapse photographs and videos and OBS Studio to control the live video Tapo feeds to YouTube. The YouTube which are then embedded in the website. The software is all running on my Win10 PC. I originally used a Raspberry Pi 4 for Agent DVR (after a lot of problems installing the software) but there were problems with the required graphics processing capabilities causing dropped frames.
