My grandmother hated sparrows. I spent a summer at her house when I was 10, and to keep me out of her hair, she bought a BB gun and told me to go kill as many sparrows as I could…..just don't shoot her cardinals and blue jays. I left every morning with the gun and a zip lock. Came home at night with a zip lock full of trophies…….I might have killed a couple blue jays on accident.
Does not help you much, unless you have a blood thirsty 10 year old.
