The old sayings about birdbrains don't appear to be true. A new study done by a scientist wearing a caveman mask who gave some crows a hard time proves that they can recognize human faces and argue and heckle those that give them a hard time and that crows can hold grudges.
The study is an important new proof that birds are a more highly intelligent animal than first believed and fuels more pressures for persons to protect bird life and become vegans.
It also seems that the glass cleaner ad where the crows play pranks on the human by closing the glass door may be more true to life than previously thought.
