Actually, crows are very intelligent... I heard this guy on NPR talkin' about how they can recognize different people... He had two people separately interact with the crows... One guy yelled at them and threw stuff at him... The other guy was peaceful around them... Next day he had the same two men separately go out to the field where the crows were... The guy who had been mean to them made them squawk and carry on... After they had settled down the other man went out and the crows were calm around him...
