It's not human's fault that birds haven't thought to invent guns yet.
Stupid unarmed birds.
Yeah, it's a pity that the bird didn't read the "No Trespassing" signs and aren't as bright as the idiot that shot it. As far as the bird killing me if I violated it's nest? I don't frequent trees and the bird coming in was more than likely an accident. They don't usually hang out in buildings as a rule. A sparrow flew into my sunroom a couple of years ago and we propped the door open and let it out. Problem solved.
