When Peter W and I checked one of our Barn Owl boxes a week or so back, we found EIGHT prey items in the box, uneaten, not surprisingly as the young owls already had full bellies. Clearly the parents are experiened hunters. The rodents are of several species: wood mouse, field vole, common/pygmy shrew and water shrew. I leave you to sort out which is which.
Talking of owls, we took my eldest granddaughter, Sophie, with us on one or our expeditions, and here she is, proudly holding an owlet in her hands (It's ok, she is legally covered by our licences!).
