In case anyone is wondering, they are not AI photos, which some people often think. Tanja has had a number of owls over the years, and this is the one I see the most.
~~In Denmark, people can aquire non-native owl species, so these owls are all human imprints, hence why they are doing non-owl things.~~
She's a photographer an author, so if you want to see or read more about her owls, there is plenty out there.
Edit: She's German, not Dutch. My mistake! Still, much work and permitting is involved.
Strict requirements apply to the keeping of owls
In Germany, keeping owls is generally allowed, but a special permit from the veterinary office is required, as all owls found here are under species protection.
As a rule, a holding permit is usually Animal parks or zoos which have trained staff. Because an animal keeper must also be trained accordingly for raptors (hunters).
And even if you want to keep the owl outdoors and let it fly regularly, you need a falconer's hunting license so as not to violate applicable rules.
If you feed an owl with live animals, you need an exemption from the veterinary office in order not to violate the Animal Body Disposal Act if you want to dispose of dead day-old chicks.
