i'm reading the genius of birds by jennifer ackerman (amazing book) and today i learned that the first ever documented case of a bird making a tool to use as a weapon against another bird was a steller's jay breaking off and sharpening a stick to wield like a lance at a crow that was taking too long at a feeding station the jay also wanted to eat at. the jay tried to stab at the crow but narrowly missed, the crow lunged back, the jay dropped the stick, and the crow picked it up with the sharp end pointing towards the jay and pursued it into the trees
imagine the guy in front of you at mcdonald's is taking too long to order and so you fashion a blade on the spot and hold him at knifepoint. and then he steals your knife and points it back at you while chasing you out of the restaurant. and also the guy is twice your size
