Unraveling the mystery behind one of nature’s most dramatic collective nouns.
What Animals Form a Murder?
When you hear the word “murder” you might think of a mystery novel or a crime drama, but in the world of animals, a murder is one of the most famous collective nouns. Herd, flock.. murder! While most people know that a group of crows is called a murder, many are unaware that several other birds in the crow-family (corvid cousins, like Ravens, Jays, and Magpies) also got swept into this eerie-sounding term.
Let’s explore what animals form a murder, why the word stuck, and how some “murders” act in groups.
Primary Animal That Forms a Murder
Crows are overwhelmingly the primary and officially recognized animal associated with the term murder (common usage: A Murder of Crows). The phrase dates back centuries and appears in medieval English hunting terminology, folklore, and poetic descriptions. The Book of Saint Albans is one such source that describes many of the dramatic (and awesome) collective nouns, like a Murder.

Why Do Crows Gather in Groups (Murders)?
Protection and Awareness
There is safety in numbers, even with birds. More eyes mean better detection of predators and advance warning of trouble.
Social Learning
Crows learn from each other, including:
- food sources
- behavior patterns
- recognizing human faces
Roosting Behavior
Winter roosts can include hundreds or thousands of birds. These gatherings help conserve warmth and energy.
Foraging Benefits
Some crows forage alone, but group foraging can help them locate new food sources more efficiently.
Historical Origins of “Murder”
The phrase “A Murder of Crows” likely emerged from:
- Medieval hunting terminology
- Folklore associating crows with omens
- Literary personification during the Middle Ages
Crows have long been linked to mystery and superstition, making “murder” a poetic (though slightly dramatic) fit.
Where You Can Spot a Murder
Crows gather in:
- Farmlands
- Suburban neighborhoods
- Forest edges
- City parks
- Large communal roosts near water
These gatherings are typically safe, social, and… honestly, quite noisy.
