This was a study starting in 2006 to see if crows could remember and identify faces, and would treat the persons accordingly
Actually I misremembered! It turns out the Cheney mask was the neutral mask, neither the kind nor the angry mask.
I think they actually went to a Halloween store to pick out masks.
Pretty interesting reading!

Was there a Cheney mask hidden under there??

I've been seeing this at University of Washington recently. Crows absolutely obliterated a particular patch of grass on the Rainier Vista, which forced the university to replace it.

I wanted to check the tweeter sphere on a crow phenomenon to see if anyone else is having the same problem. The crows here in Auburn have been ripping up the grass around here. I mean really tearing it up and leaving huge piles and chunks of grass in their wake. Looks like aeration jobs from hell everywhere. They've torn up sections of the grass by Auburn High School, parts of my parents yard, neighbors yards, etc. None of us have ever seen crows wreak destruction on grass like this before. We have heard through the grapevine it's because they are going after grubs, so maybe there is some unusually large grub crop and they are going crazy for them and tearing out the grass to get to them?
