Crows are pretty smart. I bet if it did, it quickly learned how to make those crude little flipbook "animation" programs in the calculator, where like 8 walks across the screen and fires decimal bullets out of the equals sign or something.
They're already tool users, so they could probably learn to do shitty stick-and-poke tattoos with broken BICs pretty easily.
There's something that delights me about imagining crows as middle/high school "bad kids."
I can't shake the feeling that we're flirting with our own downfall as a species, here, and yet it's hard to be too angry. They're just feathery cats with beaks.
