They're famously super smart and very social, they'll peacefully share their habitat with squirrels but they have no qualms against eating a squirrel carcass, and I don't ever remember seeing a crow attack a squirrel. If the crows had any human influence at all, it would surely be fait-accompli that squirrels would need to learn to defend or disguise themselves because crows would be nothing but black hell raining down from the skies.
