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
