#CROW NO

Tail Pulling is a behavior noted in many corvids. The practical application is to create a distraction that will allow the birb to make off with the target’s food. Imagine being in the lunch room and a large fellow has a Twinkie you covet. You can’t just take it from him because he’ll defend his Twinkie. But if you thwap him on the back of his neck and then dash around to snag the Twinkie while he investigates, you stand a decent chance of enjoying spongey goodness. This is basically that in birb form.

Sorry to hijack a little, but to put it bluntly, corvids are also pretty BALSY. They are more than prepared to harass other huge birds of prey which could deal them a lot of damage. There’s plenty of cases of corvids ‘riding’ other birds as well. It’s often to harass the larger bird out of the area, but as @red3blog said, they quite often (in layman’s terms) enjoy fucking shit up for fun.
