I guess everyone misunderstood my question.

I know that the corvids recognize people - especially me.

My question is about them purposefully excreting on others they don't have a
good relationship with if they don't like them being so close to their
activities as a form of warning or punishment. And purposely not hitting
someone they interact with in a good manner with their excrement.
