If you want more details, or can’t view the video, read more about how the vending machine actually works.
When I was living in Winnipeg, my girlfriend’s mom had a crow that used to stalk her walking to the bus each morning, and from the sounds of it, if she’s actually done something to offend the crow, the crow might not let her forget it either.
I knew crows were smart, but I honestly had no clue crows were this smart. I have friends that I don’t think would figure out this vending machine.
Oh, and apparently Magpies can recognize themselves in a mirror, which is potentially even more amazing.
