Extra camera fitted on ledge to try to read the leg ring number on one of the owls. Let’s see if it works…

Success! We now know the whole leg ring number and have identified the barn owl having hatched last year at a nesting site only about four miles from us.

The barn owls are at it already and there’s no doubt which one is the male. Several times a day too, so at this rate we should be seeing the first egg in a few days.

It’s now getting a little confusing. Today there are two owls in the nest box but one of them doesn’t have a ring on its leg so isn’t one of the two owls who have been visiting this week. So we now have at least three owls.

The two owls who have each been visiting the nest box seem to know each other a little better than we thought. They’re actually a pair and clearly like the nest box so fingers crossed that they settle in and do what owls do in spring!

The new owl has settled in for the day and has time to bring up an owl ‘pellet’. This is perfectly normal behaviour: it’s the undigestible remains of its last meal (such as a field vole or mouse). If the owl stays, within a few weeks the bottom of the nest box will disappear under a thick layer of these pellets. Lovely!

After a few weeks of an empty nest we had a visitor last night. Though a brief appearance, it was long enough to not only see the tag on the owl’s leg but also read its number, so hopefully we’ll know whether it is one of our previous owls or a new one. If it is new we’ll find out where it’s come from!

Two days later and another owl appears in the nest box. This one also ringed on the same leg but the number is different. Unfortunately we can’t read the whole number so won’t be able to tell where it’s come from.

Finally we have a working hootycam (after the old ones were disabled by a squirrel), but an empty nest box and looks like it has been empty for a while. Plenty of time though: it wasn’t until March last year that barn owls first appeared.

After a few weeks of no cameras in the nest box (thanks to something nibbling the cables up in the tree) we have fixed the technical issues and now have a good view of the inside of the nest box, where the new barn owl is settling in for the winter. She (see the black dots on her front) isn’t ringed and doesn’t look like our previous owls, so is likely new to the area.

The black blob on the bottom of the nest box is a fresh barn owl pellet and the first sign that an owl is around and might be interested in settling in.

A search back through the nest box camera’s saved clips reveals all. The barn owl has been visiting for a couple of days and even rested all day on Friday. We don’t know if it’s male or female, or if it is one of the adults from this year (it is unlikely to be any of the fledglings). We can’t see if it is ringed yet either. Will let you know more when we do.

Almost exactly to the day a barn owl starts to visit the nest box. It was 1 October when we first spotted one last year https://tiptonscroft.org.uk/blog/new-tenant/.

The youngest owlet has finally dispersed and the nest box is now empty. It’s been a successful year and there are now three new barn owls somewhere out there in the Shropshire countryside. This brings our total owls bred to 11 since we started in 2018.

The nest box shouldn’t be empty for long, but hopefully we have enough time to clean it out and make any repairs needed before another (or possibly the same) couple of barn owls settle in.

Three great tits take an interest in the empty nest box.
