Temple Valley - This is one of half-a-dozen crow warning signs that lie along a block-long-stretch of my son's school route.

These aren't your garden variety blackbirds, these are humongous jungle crows. At least the Tokyo Metropolitan Government is (or maybe was) doing something to stop these menacing marauders from the sky. The Washington Post's Blaine Harden filed this report in 2009 from the front lines of the municipality's decade-long war with this avian adversary: In Tokyo, Hitchcock Isn't Around, But He Seems to Have Sent the Birds.
