There were 8 eggs, 7 of which hatched.
17.6.21 smallest nestling died.

In response to suggestions which have been occasionally posted in the chat box, we would like to clarify that at the Charter Group of Wildlife Ecology, we use nest boxes (including this one) large enough to fledge very large broods - the largest successfully raised brood consisted of 11 barn owl fledglings. This particular box saw 7 nestlings fledge only last year. A very good test to see if a nest box is appropriate is to observe whether the parents return to it having raised a brood. Over the last 17 years, we have recorded thousands of such cases. The evidence we have compiled over years of practice does not justify suggestions that the nest boxes we use are either too large or too small. Instead, it demonstrates clearly that the productivity of a nest box correlates strongly with the availability of food in its neighborhood. This can be seen with other CAMs that have large boxes but with less successfully barn owl pairs (i.e. 3-4 nestlings only).
