Every year, our ecologists work with the British Trust for Ornithology to ring barn owls at Knepp. 🦉
This can only be done under licence from the BTO. So, no, we’re not, errr, ‘winging it’.
Barn owls are a key indicator species — their populations reflect the health of the wider ecosystem.
The band that we attach to one leg is lightweight and uniquely numbered. As you can see, the owlets are relatively relaxed about the process, which takes just moments. When we return the juveniles to the nest their parents are quick to return.
Ringing is important. It allows researchers to identify that individual bird for the rest of its life, should it ever be seen or caught by birders or ringers.
The data tells us how far young owls travel from their nest site to find their own territory; how long barn owls typically live in the wild, and what causes mortality; and which landscapes best support healthy populations.
It also helps us understand the threats that owls face - problems like road collisions and secondary poisoning from rodenticides. (If you ever find a dead owl with a ring on its leg, do contact the BTO.)
This information, built up over decades, is invaluable for the conservation of these wonderful creatures. 🌿
