My dad always told a story about a guy at work who spotted a crow nest not too far up a tree and decided he would steal the baby crow and raise it. The crows attacked him as he did it and in the end the baby crow died in his care. Sad. But at least after that my dad said every single day he would pull up to work and if any crows were there they would dive bomb him. Only him. My dad said this carried on for years.
Assuming that the crows attacking years later were not conveyed a detailed account of the original events, this is an interesting model also applies to many human group behaviors:
"this is the guy we hate, it gives a great feeling of community expressing that hate. Yeah, there's probably a reason why we hate him, but that's besides the point"
