Imagine if you had just watched Alfred
Hitchcock's "The Birds", and you walked outside and saw this! You would run screaming back inside and loading a gun.

Those are crows and our approximate head count as to how many crows is
About 500.
 We were afraid to get out of our car, because we could hear the crows violent assault on the roof of the car.
Poop, poop, poop.
A medium purple in colour, did not match my car.
