Facebook’s machine translation isn’t great. There’s nothing here that’s even remotely close to the word for “machete.” But the translator might have lost its mind because “Kauz” was misspelled (there’s no “t” in it). And sometimes unique names make the computer go crazy.
I couldn’t find any info about this particular owl, but my best guess would be some kind of conservation program. There are quite a few of those (for all kinds of animals) in the German-speaking countries.
This particular place is a nature park and raptor rescue near Frankfurt. Very cute little owl!
Fascinating, especially how many different animals are carved on it. I wonder who this would have belonged to.
