Money-quote: To test whether crows know and can analyze the contents of their brains, neurobiologist Andreas Nieder of the University of Tbingen in Germany trained two birds to peck a red or a blue target on a panel, depending whether they saw a faint light. Nieder kept varying the rule, with the birds told which color meant what red = saw it, or blue = saw it only after the flash. That required the crows, Glenn and Ozzy, to keep monitoring their brains; they had a second or two to figure out what they had seen and tell Nieder by choosing the corresponding target.They're also excellent at puzzles, using tools, and they'll remember your stupid face if you mess with them and tell their kids what a jerk you are so generations of crows will hate you. ...
