And a crow group is called a Murder?
Many birds live alone, but crows live in a group called a murder.
Most people would call it a Flock of Crows.
One could think of a murder of Crows to be the "poetic term" .
The word for this grouping appears in the title of the short story "Murders in the Rue Morgue" is a well-known short story by Edgar Allan Poe.
Murder - The Crow Society
Very clever...
A Crow's investigation is for the birds...
