what type of bird was it?

Neighborhood conflicts - It’s better to prevent them than to sort them out once they start. It would be interesting to know exactly what OP said to the neighbor and how it was said before assuming that the neighbor is just an insane A-hole. (And neighbor might be just that.) Once things get heated, it’s very hard to calm things down. We cannot fix OP’s problem with their neighbor. But this is a good example of why it’s best to start off on a pleasant tone with your neighbors.
