Why is a murder of crows called a murder?

Introduction

The English language is filled with fascinating collective nouns for animalsโ€”a pride of lions, a school of fish, a flamboyance of flamingos. However, few are as evocative or slightly chilling as a "murder" of crows.

Historical Roots and Folklore

During the 15th century, the English nobility developed a specialized vocabulary for groups of animals, known as terms of venery or hunting terms. While many of these terms were purely descriptive (like a leap of leopards or a skein of geese), others were heavily influenced by cultural beliefs, superstitions, and folklore.

Crows are scavenger birds that frequently gathered in large numbers around battlefields, gallows, and sites of death to feed on carrion. Because of their black feathers, haunting caws, and association with decaying remains, people in medieval times associated them with death, doom, and bad omens.

The Evolution of the Term

Over time, these folklore associations solidified in popular culture and literature. Authors and poets embraced the dark imagery, cementing the term "murder" in the English lexicon. While ornithologically a group of crows is simply a flock, the term "murder" survived because of its poetic resonance and cultural impact.

Summary

Ultimately, calling a group of crows a "murder" is a linguistic reflection of medieval superstitions, where the birds' scavenging habits near battlefields linked them permanently to concepts of death in human imagination.
