50 Collective Nouns for Groups of Animals

You know which animals move in packs, schools, and herds, but what about a wake, a business, or a flamboyance? Collective nouns—a.k.a. words that indicate a particular group—date back to the 15th century, and many of the animal variety can be traced to the Book of St. Albans, a manual of sorts for gentlemen published in 1486. (Whether or not they were actually part of popular usage at the time, or simply became popular because of the success of St. Albans, is up for debate.) Though the collective nouns on this list may seem a little strange or weird today, at the time they were anything but.

1. A Cackle of Hyenas

While clan is the much more accepted term, there’s something very appropriate about cackle. And though spotted hyenas’ laughs and giggles sound entertaining, they’re really how the carnivores express anger, frustration, and warnings to stay away.

2. A Shrewdness of Apes

This term has around since the late 1400s—at the time, shrewdness referred to the mischievous nature of apes, though knowing now how intelligent they are, the term still works.

3. A Raft of Otters

According to the Oxford English Dictionary, many aquatic animals, such as ducks or puffins, also form rafts.

4. A Murder of Crows

In the 15th century, crows were considered to be omens of death and messengers from the devil or evil powers.

5. A Scurry of Squirrels

Scurries are fairly unusual since squirrels are not pack animals by nature, so the more commonly used dray refers to a nest consisting of a mother squirrel and her young.

6. A Wake of Vultures

For vultures, a “wake” specifically refers to a group feeding on a carcass. The less morbid terms kettle and committee are reserved for groups that are flying and resting in trees, respectively.

7. A Battery of Barracudas

Just one barracuda is intimidating, but a battery of them? Time to retreat!

8. A Muster of Storks

Muster can also be used for groups of peacocks/peafowl (though an “ostentation” of peacocks is much more illustrative).

9. A Walk of Snails

Considering that walking is one of the things a snail cannot do, this seems like an unusual choice. Perhaps the lesser-known (but still accepted) escargatoire would be more accurate.

10. A Parliament of Owls

It’s unclear when this phrase was invented, with examples dating to the late 19th century. But its origin is likely an allusion to Chaucer’s poem “The Parliament of Fowls,” alongside the use of parliament as a collective noun for rooks.

11. An Ambush of Tigers

Since tigers tend to be solitary creatures, a grouping of them would certainly feel like an ambush.

12. A Coterie of Prairie Dogs

While full towns of prairie dogs are called “colonies,” the close-knit, individual family units are called “coteries.”

13. A Mutation of Thrushes

An ancient and medieval belief that thrushes (a kind of bird) shed and regrew their legs each decade led to the collective term mutation.

14. A Memory of Elephants

Sure, a “herd” of elephants is the more common collective, but memory is also a term that is used. We’re not sure why a “pack” of pachyderms didn’t catch on, though.

15. A Skulk of Foxes

This term likely came about because mother foxes raise their young while burrowed underground.

16. A Scold of Jays

Jays also hang in “bands” and “parties.”

17. A Covey of Quails

While they can also group as a “flock” or a “bevy,” a “covey” of quail sounds much more poetic.

18. A Hover of Trout

As trout tend to swim in groups near the bottom of a lake or river, they likely look like they’re hovering over the bed of the waterway. Alternately, it may come from an old term for an overhanging rock where fish—like trout—can hide.

19. A Bale of Turtles

Supposedly, a group of turtles who are cozy in their shells would look like a field of round or squarish hay bales.

20. A Rhumba of Rattlesnakes

Because, perhaps under circumstances that didn’t involve a large number of snakes, that many rattles in one place would make you want to dance.

21. A Charm of Hummingbirds

If just one hummingbird is charming, can you imagine how charming a whole group of them would be?

22. A Business of Ferrets

The Book of Saint Albans gave ferrets the collective term busyness (“besynes”), which today has become “business.”

23. A Stubbornness of Rhinoceroses

They can collectively be called a “crash” of rhinos as well.

24. A Prickle of Porcupines

Could this term be any more apt?

25. An Implausibility of Gnus

Gnus are also known as wildebeest. Who knew?

26. An Unkindness of Ravens

Ravens may not be friendly fowl. They will often gang up on their prey or animals that enter their space. And because of the impression that they are an ominous presence, an unkindness of ravens can also be called a “conspiracy.”

27. A Harem of Seals

Specifically, when you have a group of females with a dominant male, it’s a “harem.” If it’s just some breeding seals hanging out, it’s a “rookery.”

28. A Mob of Kangaroos

And just like in human mobs, there’s usually a leader (a “boomer,” or adult male) who is only in power for a short while before being challenged and defeated by a rival boomer.

29. A Gam of Whales

Gam is a possible derivative of gammon, meaning “talk intended to deceive.” Considering scientists have only just recently begun thinking they could decipher whale calls, we’d say the gam’s gammon is pretty effective.

30. A Pod of Pelicans

They can also be called a “squadron.”

31. A Generation of Vipers

A group of snakes is generally a “pit,” “nest,” or “den,” but they’re generally thought of as solitary creatures, so collective nouns for specific types of snakes are more fanciful. Generation likely originates from the King James translation of the Bible, in which Matthew 23:33 reads “Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?”

32. A Descent of Woodpeckers

Woodpeckers are known for their headbanging style of foraging for food, but another method some have is to quickly dive-bomb anthills and termite mounds.

33. A Run of Salmon

A salmon run isn’t just the mass migration of salmon up the river—a “run” of salmon is also the name of a group of the fish.

34. A Kaleidoscope of Butterflies

Groups of butterflies can also be called “flutters.”

35. A Wisdom of Wombats

Wombats have large brains and are incredibly playful, which is often viewed as a sign of intelligence.

36. A Rout of Wolves

While pack is definitely the better-known term today, a very old term for wolves is rout, a word that comes from Middle French for “company.”

37. A Shiver of Sharks

The term shiver applies a bit more to nervous humans when they see a large group of sharks, which is perhaps why the term has caught on in recent years.

38. A Scourge of Mosquitoes

They’re more commonly called a “swarm,” but scourge sounds just as accurate.

39. A Sleuth of Bears

This isn’t a reference to any detective work bears may or may not do—it’s derived from the Old English word for “sloth,” meaning slow (and sloth itself is sometimes used as a collective noun as well). 

40. A Gaze of Raccoons

The males are “boars” and the females “sows.”

41. A Siege of Herons

When herons pick a new lake or river to rest in, the fish there would certainly feel under siege.

42. A Flamboyance of Flamingoes

Kudos to the creator of this perfect term.

43. A Destruction of Cats

A “destruction” refers specifically to a group of wild or feral cats. A group of domesticated cats is a “clowder.”

44. A Fever of Stingrays

At the very least, swimming with a fever of stingrays would surely cause your blood pressure to rise.

45. A Skein of Geese

A “skein” is used specifically when geese (or other wild birds) are flying, while the alliterative gaggle is the term for grounded or domestic geese.

46. A Bunch of Worms

Not terribly creative, but when in doubt, just say “a bunch” of whatever.

47. An Exaltation of Larks

An “exaltation” of larks also dates back to the 15th century Book of Saint Albans (which, because of its heraldry section, also happened to be the first book in England to be printed in color).

48. A Family of Sardines

There are more than a dozen fish who can be labeled “sardine” in the supermarket. So in this case, family means a large grouping, rather than parents and children.

49. A Barrel of Monkeys

Not just a game—it’s a real term. Monkeys can also congregate as a “carload,” “troop,” or “tribe.”

50. A Dazzle of Zebras

They’re more commonly called a herd, but a “zeal” or “dazzle” of zebras has such a nice ring to it.
