If you were asked to name an onomatopoeic word, you’d probably says something like boom, boing, whizz, or smash. They’re all perfectly good examples, of course, but onomatopoeia is actually responsible for a lot more words than you might think. For instance, etymologists believe that pebble might have been coined to imitate the sound of flowing water. Laugh might have been invented to sound like, well, a laugh. Owl, crow, and raven are all descended from Old English words (ule, crawe, hræfn) that were meant to imitate the owl’s hoot and the crow’s and raven’s squawks. And the 32 names listed here are all meant to represent the bizarre whoops, chips, peeps, and wows made by the animals they describe.

1. Ai

As well as being a contender for the world’s shortest animal name, ai (which should be pronounced “ah-ee") is another name for a three-toed sloth, especially the pale-throated sloth, found in the far northeast corner of South America. Although sloths are generally fairly docile, the name ai is apparently meant to resemble the high-pitched cry they can make when they’re agitated or alarmed.

2. Bittern

As the name of a type of water bird, no one is entirely sure where the name bittern comes from. The most likely theory is that it is a mangled version of a Latin word essentially meaning “bull-heron”—and if that’s the case, then the name is probably meant to be a reference to the bittern’s bizarre booming or “mooing” call.

3. Bobolink

Bobolinks can produce very long and surprisingly complex songs, but their usual go-to noise is a brief four-note call that’s commonly said to sound like someone saying “Bob-o-Lincoln.” The name Bob-o-Lincoln eventually was shortened to bobolink in the 1800s.

4. Catbird

Catbirds are family of medium-sized songbirds found across the Americas, Africa, and Australasia. Their name refers to their raucous wail-like calls, which supposedly sound like the mewing of a cat. This bizarre sound is even the origin of the birds’ taxonomic name: ten of the world’s 14 known species of catbird belong to a genus named Ailuroedus, which literally means “cat-voiced.”

5. Chiffchaff

The chiffchaff is one of the most widespread members of the warbler family of birds, found across Europe, western Asia, the Middle East and north Africa. Throughout that range, it’s been given a number of different names meant to replicate its simple but instantly recognisable two-note call. It might be called the chiffchaff in English, but in Dutch it’s the tjiftjaf; in Welsh it’s the siff-saff; in Turkish it’s the çıvgın (pronounced “chiv-gin”); and in German it’s the Zipfzapf.

6. Chipmunk

One theory claims that the name chipmunk is an English interpretation of a native Ojibwe word, ajidamoo, meaning something like “red squirrel.” But because chipmunks were originally known as “chipping squirrels” in English, it seems more likely that the name is actually an English invention, in which case it’s probably meant to describe their short “chipping” call.

7. Chowchilla

The chowchilla is type of logrunner, a small thrush-like bird, that’s native to Queensland, Australia. For a bird not much larger than a robin, the chowchilla has a particularly noisy call that to early European colonists and explorers apparently sounded like “chow-chilla-chow-chow.” The chowchilla was also once known as the “auctioneer bird,” apparently because (with a bit of imagination) its song sounds like an auctioneer's incessant chattering.

8. Chuck-will's-widow

A cousin of the better-known whippoorwill, the chuck-will’s-widow is another species of nightjar (a family of nocturnal birds related to swifts and martins) native to the southern United States and much of Central America. Dozens of different species of nightjar are found all over the world, and they all share incredible camouflaged plumage and strange whooping calls—so if the “whippoorwill” makes a noise that sounds like poor Will is about to be whipped, then the “chuck-will’s-widow” makes a sound like poor Will’s widow is about to be chucked.

9. Corncrake

Crakes are a large family of birds related to coots, moorhens and rails. No one is entirely sure whether their name was coined in English (in which case it’s probably meant to echo the weird croaking sound they make), or whether it comes from an old Scandinavian word for a crow, krakr (which was likewise invented to sound like the croaking of a raven). In the case of the corncrake bird in particular, however, the name is doubly onomatopoeic: the corncrake’s Latin taxonomic name, Crex crex, as well as its common English one, is meant to reproduce its bizarre, grating call.

10. Devil-in-the-trees

We’ll get onto geckos in a moment, but first it’s worth singling out the New Caledonian giant gecko or “devil-in-the-trees” in particular. The largest species of gecko in the world, the New Caledonian giant reaches an impressive 14 inches in length from nose to tail. Among English speakers (and gecko enthusiasts) it’s known as the leachie; both this and its scientific name Rhacodactylus leachianus are meant to honour the 19th century English zoologist William Elford Leach. But to the native New Caledonians, the leachie is better known as the devil-in-the-trees, thanks to the spooky, demonically rasping noises that it makes—which, in the darkness of a tropical forest, could understandably sound fairly unnerving. Local tradition even claims that the giant gecko’s super-sticky feet give it the ability to pull a soul out of a person’s body.

11. Dickcissel

Also known as the little meadowlark, the American dickcissel bird takes its name from its chirruping call that, with a little bit of imagination, supposedly sound like a repeated “d-d-dick, ciss-ciss-cissel.”

12. Dik-dik

Barely a foot tall at the shoulder and weighing as little as 8lbs, dik-diks are among the smallest antelopes in Africa. Their name derives from their alarm call, and is meant to imitate the short, repeated notes the dik-dik produces when threatened.

13. Flicker

One of only a few species of woodpecker that are migratory, American flickers are said to take their name from their chattering, “flickering” call. A number of the birds’ regional nicknames—including harry-wicket, walk-up, heigh-ho and wake-up bird—are likewise said to be based on their characteristic back-and-forth calls.

14. Gang-gang

The peculiar croaking noise made by the gang-gang cockatoo of southeast Australia has been likened to everything from a creaking wooden door to a cork being pulled from a wine bottle. However you might want to describe it, the onomatopoeic name gang-gang was adopted into English from a Wiradhuri name that was supposed to imitate it.

15. Gecko

They might be best known for their ability to walk upside down on the ceiling thanks to their amazingly specialized feet, but geckos also make a name for themselves (quite literally) by producing a whole range of bizarre croaking sounds—including a characteristic two-note rising and falling call that is believed to have given them their name.

16. Grey go-away-bird

Yes, this is a real bird. Yes, it’s grey. And yes, it’s call really does sound like someone saying “go away.”

17. Grunt

It’s fair to say fish aren’t among the noisiest of animals, but the grunt is at least one exception. Grunt fish are found mainly in the north and west Atlantic, and are so called because they produce a loud scraping “grunt” sound when threatened. The sound is made by grinding together tiny rows of pharyngeal teeth the fish have hidden behind their gills.

18. Hoolock

The hoolocks are a family of three different species of gibbon native to parts India, Bangladesh and southwest China. Their name comes from the local Assamese language of east India, and is supposed to replicate the raucous whooping sound the hoolocks make.

19. Hoopoe

The hoopoe is a striking-looking songbird whose name is meant to imitate its strange whooping call. Their bizarre appearance has also helped make them the frequent subject of myths and folktales over time: the Ancient Egyptians worshipped them and drew pictures of them inside the pyramids; the Romans believed that they were filthy creatures because they fed on dung and frequently nested in graveyards; and at least one old European legend claims that the younger birds look after the older ones in their old age, restoring their youth by plucking out dying feathers and licking blindness from their eyes.

20. Katydid

Katydids make their loud and often three-syllable “ka-ty-did” call by rubbing their forewings together. They hear each other, incidentally, with ears located on their front legs. There are more than 6000 species in the katydid family, found on every continent except Antarctica.

21. Macaque

The name macaque was borrowed into English via French in the late 17th century, but it’s thought to originally derive from an old Bantu name, kaku, for any of the numerous monkey species found in West Africa. The name kaku is in turn supposed to be imitative of a monkey call, and it’s from the plural form of kaku—namely makaku in Bantu—that the word macaque eventually evolved.

22. Morepork

Also known somewhat less memorably as the Tasmanian spotted owl, the morepork is a small forest-dwelling owl found in southern Australia and New Zealand. Its name is supposed to imitate its characteristic hooting call, which is supposed to sound like someone asking for “more pork.” Or at least that’s one interpretation—other local names for the morepork that are likewise said to replicate its call include boobook, bug-bug, ruru, and herooroo.

23. Peabody

The American white-throated sparrow is also known as the peabody bird. It might be tempting to presume that name must refer to the bird’s discoverer, but actually it’s a concocted name based on nothing more than the similarity of the bird’s call to the surname Peabody. As the Oxford English Dictionary explains, the peabody’s song is “rendered as ‘Sow wheat, Peabody, Peabody…’” Another interpretation claims it sounds more like “Old Sam Peabody, Peabody!”, while another suggests its call sounds more like “O, sweet Canada, Canada.” You can decide for yourself here.

24. Peewit

A type of plover with characteristic green plumage and a long curled crest, the northern lapwing has a number of nicknames in English—including the peewit, the swipe, the peepsweep, the teewhit, and the teeack—every one of which is supposed to emulate its noisy alarm call. The common name lapwing, incidentally, refers to the bird’s tactic of feigning a broken wing in order to distract predators from their nest when they feel threatened.

25. Petchary

The petchary is a large shrike-like bird found across the Gulf of Mexico and the Caribbean, from Florida, Cuba and the Bahamas in the north to Panama, Colombia and Venezuela in the south. First recorded in 1840, the name petchary is apparently meant to imitate the bird’s trailing, descending three-note call—though today, it is better known as the gray kingbird.

26. Piet-my-vrou

Piet-my-vrou is another name for the red-chested cuckoo, a species of cuckoo found across much of sub-Saharan Africa. Cuckoos are well known for their instantly recognizable call, and it’s the loud three-note descending call of the piet-my-vrou (which literally means “Pete my wife” in Afrikaans) that gives it its name.

27. Thermometer cricket

Okay, we’re bending the rules a little for this one. Also known as the snowy tree cricket, the thermometer cricket is so called not because of the sound makes, but the rate at which it makes it. Like all crickets, the thermometer cricket makes a soft chirruping sound. Count the number of chirps it makes in 15 seconds, then add 40 to that total, and you’ll have a fairly accurate estimate of the current ambient air temperature in degrees Fahrenheit. Incredibly, there’s a wealth of scientific research behind this calculation, and even a somewhat complex rule—known as Dolbear’s Law—to describe it.

28. Veery

The veery is an American thrush, whose name according to Merriam-Webster is “probably imitative of its downward-spiraling song.”

29. Whistlepig

Never heard of a whistlepig? Actually, you probably have. This is just another name for the American groundhog, so called because it makes a loud whistling sound when threatened or alarmed.

30. Wistiti

The wistiti is another name for the common marmoset, a small monkey native to the far northeast of Brazil. It derives from the French word for a marmoset, ouistiti, which is itself meant to imitate the creature’s high-pitched cry.

31. Wow-wow

Gibbons are famous for their lengthy and surprisingly complex songs, and the whooping or “wowing” call of the wow-wow or wawa—a local Indonesian name for either the agile gibbon or the silvery gibbon—is no exception. Sadly both species are now listed as endangered, due to their localized distribution and on-going habitat destruction.

32. Zyzzyx

The bizarre Z-hogging word Zyzzyx has two claims to fame. Firstly, it’s often touted as the last dictionary word in the English language. Secondly, it appeared in the title of the 2006 movie Zyzzyx Rd—which set an all-time record when it earned just $30 at the box office. Besides that, it’s also the name of a genus of sand wasp supposedly suggested way back in 1930s as an attempt to imitate the characteristic buzzing sound the insects make.
