The time has come. After I converted my two nest boxes over a year ago and equipped them with an additional side camera, I was finally able to make a great discovery for the first time this evening:
The first sleeping great tit in the converted nest box and the first sleeping tit in over 2 years.
Now I hope of course that this is a preliminary check to see whether the box is suitable for a nest and a nursery ?.
We can be curious…
