A Murder of Crows

More on the PBS Crow Piece, from the Seattle PI:

Crows recognize and remember human faces, a tell-tale sign of the birds' uncanny intelligence.

Sure, they have a reputation for being crafty creatures -- ominous, even. But a new show from PBS concludes they're actually some of the world's smartest animals.

The University of Washington plays a big part in "A Murder of Crows," which premiered Sunday at 8 p.m.

UW researchers wore caveman masks when they caught and released several crows on the university campus. Later, they donned the masks again and walked around the UW, observing how crows reacted. Their finding? The birds sounded an alarm every time they saw the masks.
