A Flock of Crows Is Called a Murder for a Reason

The ominous term for a group of crows isn't a modern invention; it belongs to a category of collective nouns known as "terms of venery" that were popularized in the 15th century. The choice of "murder" likely stemmed from a dark folk belief that crows, long associated with battlefields and the gallows, would form tribunals to judge and sentence their own kind. Observers saw large, raucous gatherings of crows and interpreted them as a court, with the subsequent death of a crow seen as a communal execution. This sinister reputation, combined with their scavenging nature and harsh calls, cemented the macabre label in the English language.

While the idea of a crow court is pure folklore, it was likely inspired by a real and fascinating behavior that scientists now understand. Crows do indeed gather around their dead in what researchers call "funerals." This gathering isn't about mourning or justice, but about investigation and social learning. When a crow discovers a deceased member of its species, it will often call out, attracting dozens of others to the site. The flock collectively observes the scene, learning to identify the potential threat—be it a predator (Review), a dangerous location, or even a specific person—that caused the death, ensuring they avoid that same danger in the future. So, what ancient observers saw as a trial was actually a crucial survival lesson.
