There’s a cool study where researchers wore masks to catch crows in traps and weigh them, do health checks etc, nothing painfully for the animals but they don’t love it, now many years later young crows from that group who weren’t even alive for that study hate on people who wear those masks. I’d like to imagine the adult crows tell horror stories around the nest to warn the young ones, but its probably much less novel ;) https://www.seattletimes.com/seattle-news/uw-professor-learns-crows-dont-forget-a-face/
