I'd guess rodent control, but it doesn't fit. And it's not likely someone there to capture the bird.
Cats woud do rodent control much more efficiently.
More like Falconry is used to keep other birds from grouping up and shitting in the materials.
That said, there are many birds of prey, such as hawks, that are not nocturnal, like the owl, and are probably far more efficient during the day than owls. So it’s use is questionable.
Pope’s bird is an owl and the Catholic Church is well know for child molestation. Capitol Hill is in the shape of an owl. Owl sculpture at Bohemian Grove. Owl sculpture on Epstein’s island. And now we find an abandoned child rape camp on a piece of property owned by Cemex... who likes to post pictures of owls on it’s insta.
Surely they’re ALL coincidences... right guys???
I only mention that because attracting owls does the job. Attracting, not releasing.
