I was working on my car in the driveway a couple of weekends ago and two crows sat in the tree in the front yard and yelled at me the entire time. I eventually got tired of them and stood up, walked over to where they were and yelled “Fuck off! You have to whole neighborhood to live in. I have to be here. You don’t!”. Surprisingly they stopped squaking at me after that. We feed them and put bird baths out for them, and they still treat us like trespassers on our own property.
