The crows in Tokyo are big, smart, nasty, all over the place, and out of control. There are warning signs in parks because they dive bomb people, occasionally bloodying them. They strew trash all over the place, ripping through unguarded vinyl garbage bags left outside for trash pick up. They **** everywhere – e.g., on cars, houses, and, occasionally, people -- and are raucous in the early mornings. I saw one eating a pigeon – not sure if it had just picked up road kill or whether it did the killing. Made a nasty mess outside my office window.
When I see 'em in my yard I pop 'em with an airsoft Python. I'd rather pop 'em with my K22 or22 OMT, but no guns here, unfortunately. They are smart rascals, tho, and usually take off before i can draw a bead on 'em.
I read a news article some years ago that said a town up north tried killing 'em and turning 'em into shishkabobs (yakitori) as a method of pest control, but that consumers did not take to the test readily.
