New or old?

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.

Different leg ring = different owl
