Watch the crow shooting video again but this time with your reading glasses on :), everytime he shoots a crow falls.
They aren't crows.
Next time
you read a post get to the end of the second line.
The great majority were rooks with possibly a jackdaw or two and one magpie.... no crows that I saw.
Mr Digweed even mentions that his "crows" have a big colony nearby; crows are relatively solitary and don't nest in colonies. Rooks do, and in consequence these are called "rookeries". No one ever heard of a "crowery".
Countryman's jest runs... "Lots of crows in a field are rooks, lots of small crows in a field are jackdaws, and a couple of really big crows are ravens".
