Researchers have recently found that crows are capable of forming long-lasting memories of who can be trusted and who can’t with only one previous experience. After they learn who is to be trusted, they have that quintessential knowledge of separating people who are likely to feed or to shoot them.
Moreover, crows share the information gathered between them, making it spread way faster than it would if each bird had to learn on its own. That’s why their adapting skills are absolutely remarkable.

Rodent population exploded. No owls or hawks would stay, because of the crows. It was terrible.
