Quoth the Raven, Nevermore? Hardly.

Crows can remember who you are. The University of Washington, Seattle did a set of experiments in 2006 to test the memory of local crow flocks. John Marzluff, the brains behind the experiment had researchers wear rubber masks (one of Dick Cheney) while capturing birds with a net launcher. For three years afterward, the crows remembered the masked faces, and alerted others of their presence. The birds took defensive measures as well by diving at the researchers. If that wasn't scary enough, future generations of birds who had never seen the masks reacted in the same manner, indicating that the crows were passing down the stigma throughout generations.
