What is a group of crows called?

The phrase “a murder of crows” dates back to the fifteenth century, when English writers invented colorful names for groups of animals. The name may come from old folk tales linking crows with death. A parliament is a group of owls; a gaggle, geese; a pride, lions.

Crows are remarkably intelligent. Researchers at the University of Washington found that crows can recognize individual human faces and remember people who threatened them for years, even teaching other crows to scold them.

Crows sometimes gather around a dead crow, calling loudly, a behavior scientists believe helps them learn about danger.
