Why Do We Call a Group of Crows a 'Murder'?

Introduction

Language is full of colorful collective nouns—a pride of lions, a school of fish, a parliament of owls. Among the most evocative and slightly eerie of these terms is a murder of crows. But how did a flock of these intelligent black birds earn such a sinister-sounding title?

Etymology and History

The term dates back to the 15th century, specifically arising from the tradition of English terms of venery (hunting terminology). During the Late Middle Ages, hunters and noblemen developed specific, poetic, and often whimsical collective nouns for various animals, birds, and fish.

While some terms described behavior (like a leap of leopards), others leaned heavily into medieval superstition and folklore.

The Folklore Connection

Crows are scavengers that frequently feed on carrion (the decaying flesh of dead animals). Because of this habit, they were often seen lingering around battlefields, gallows, and sites of disease or death.

In European folklore, particularly in medieval Britain, crows were heavily associated with bad omens, witchcraft, and death. Consequently, language reflected these associations. Other grim collective nouns from the same era include an exaltation of larks, but also a dule of doves (from the French deuil, meaning mourning) and a murder of crows.

Modern Scientific Context

While the term "murder" is deeply entrenched in literary and popular culture, ornithologists and scientists generally refer to them simply as a flock or a roost. However, the poetic resonance of "murder" remains popular due to the bird's striking appearance, intelligence, and dark historical reputation.
