The caption called this a sperlingskauz, which was translated to "Sparrow Owl."
I'd never heard of a Sparrow Owl, but the EPO has a scientific name that is Latin for "Sparrow Owl" that I will assume is how it got its German name.
Oh cool! I'll have to keep this one in mind for if I ever get to tell jokes in German lol
I took it to mean you can just hoot at them as a way of saying hello ๐ค
That too lol
