Just saw an interesting study on crow roadkill on PBS> Oddly enough, 98% of all crows hit on the roads are struck by trucks, not cars, though cars far predominate in traffic.

An ornithological behaviorist has found the reason. When there is something on the road that attracts crows, one of the murder stays in a tree to act as a sentry. Unfortunately, the sentries can only say "cah, cah" so they remain silent when a truck is coming.
