What do you call the plural of "crow"? Or, The Birds attack humans in Britain

Life imitates Gothic: crows are attacking humans in Warwickshire.

Linda Pheasey, who lives in Milton Avenue where the crows congregate, said: "These crows started coming last summer and they have become more and more aggressive in the way they are attacking cars.

"And now, like I said, they have attempted to attack a lady and she was pretty frightened by it."

Now, remember Hitchcock got the idea from her.
