Hoopoes (/ˈhuːpuː,ˈhuːpoʊ/) are colourfulbirds found acrossAfrica,Asia, andEurope, notable for their distinctive "crown" of feathers which can be raised or lowered at will. Three living and one extinct species are recognized, though for many years all of the extant species were lumped as a single species—Upupa epops. In fact, some taxonomists still consider all three speciesconspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated asLeast Concern on TheIUCN Red List of Threatened Species. However, their numbers are declining in Western Europe.[3] Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai,Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round.
ThegenusUpupa was introduced in 1758 by the Swedish naturalistCarl Linnaeus in thetenth edition of hisSystema Naturae.[4] Thetype species is theEurasian hoopoe (Upupa epops).[5]Upupa and ἔποψ (epops) are respectively theLatin andAncient Greek names for the hoopoe; both, like the English name, areonomatopoeic forms which imitate the cry of the bird.[6][7]
The hoopoe was classified in thecladeCoraciiformes, which also includeskingfishers,bee-eaters, androllers.[8] A close relationship between the hoopoe and thewood hoopoes is also supported by the shared and unique nature of theirstapes.[9] In theSibley-Ahlquist taxonomy, the hoopoe is separated from theCoraciiformes as a separate order, theUpupiformes. Some authorities place the wood hoopoes in the Upupiformes as well.[10] Now the consensus is that both hoopoe and the wood hoopoes belong with the hornbills in theBucerotiformes.[11]
Thefossil record of the hoopoes is very incomplete, with the earliest fossil coming from theQuaternary.[12] The fossil record of their relatives is older, with fossilwood hoopoes dating back to theMiocene and those of an extinct related family, theMesselirrisoridae, dating from theEocene.[10]
Formerly considered a single species, the hoopoe has been split into two separate species: theEurasian hoopoe and theMadagascar hoopoe. One accepted separate species, theSaint Helena hoopoe, lived on the island ofSt Helena but became extinct in the 16th century, presumably due to introduced species.[12]
The genusUpupa was created byLinnaeus in hisSystema naturae in 1758. It then included three other species with long curved bills:[13]
Formerly, thegreater hoopoe-lark was also considered to be a member of this genus (asUpupa alaudipes).[14]
Two extant species are recognised:[11]

Hoopoes are widespread in Europe, Asia, and North Africa, Sub-Saharan Africa and Madagascar.[15] Most European and north Asian birdsmigrate to the tropics in winter.[16] In contrast, the African populations are sedentary all year. The species has been avagrant inAlaska;[17]U. e. saturata was recorded there in 1975 in theYukon Delta.[18] Hoopoes have been known to breed north of their European range,[19] and in southern England during warm, dry summers that provide plenty of grasshoppers and similar insects,[20] although as of the early 1980s northern European populations were reported to be in the decline, possibly due to changes in climate.[19]
The hoopoe has two basic requirements of its habitat: bare or lightly vegetated ground on which to forage and vertical surfaces with cavities (such as trees, cliffs or even walls, nestboxes, haystacks, and abandoned burrows[19]) in which to nest. These requirements can be provided in a wide range of ecosystems, and as a consequence the hoopoe inhabits a wide range of habitats such as heathland, wooded steppes, savannas and grasslands, as well as forest glades. The Madagascar species also makes use of more dense primary forest. The modification of natural habitats by humans for various agricultural purposes has led to hoopoes becoming common in olive groves, orchards, vineyards, parkland and farmland, although they are less common and are declining in intensively farmed areas.[15] Hunting is of concern in southern Europe and Asia.[18]
Hoopoes make seasonal movements in response to rain in some regions such as in Ceylon and in the Western Ghats.[21] Birds have been seen at high altitudes during migration across theHimalayas. One was recorded at about 6,400 m (21,000 ft) by the first Mount Everest expedition.[22]
In what was long thought to be a defensive posture, hoopoes sunbathe by spreading out their wings and tail low against the ground and tilting their head up; they often fold their wings and preen halfway through.[23] They also enjoy taking dust and sand baths.[24] Adults may begin their moult after the breeding season and continue after they have migrated for the winter.[25]
The diet of the hoopoe is mostly composed of insects, although small reptiles, frogs and plant matter such as seeds and berries are sometimes taken as well. It is a solitary forager which typically feeds on the ground. More rarely they will feed in the air, where their strong and rounded wings make them fast and manoeuverable, in pursuit of numerous swarming insects. More commonly their foraging style is to stride over relatively open ground and periodically pause to probe the ground with the full length of their bill. Insect larvae, pupae and mole crickets are detected by the bill and either extracted or dug out with the strong feet. Hoopoes will also feed on insects on the surface, probe into piles of leaves, and even use the bill to lever large stones and flake off bark. Common diet items include crickets, locusts, beetles, earwigs, cicadas, ant lions, bugs and ants. These can range from 10 to 150 millimetres (0.4 to 5.9 in) in length, with a preferred prey size of around 20–30 millimetres (0.8–1.2 in). Larger prey items are beaten against the ground or a preferred stone to kill them and remove indigestible body parts such as wings and legs.[15]
Hoopoes aremonogamous, although the pair bond apparently only lasts for a single season. They are alsoterritorial. The male calls frequently to advertise his ownership of the territory. Chases and fights between rival males (and sometimes females) are common and can be brutal.[15] Birds will try to stab rivals with their bills, and individuals are occasionally blinded in fights.[26] The nest is in a hole in a tree or wall, and has a narrow entrance.[24] It may be unlined, or various scraps may be collected.[19] The female alone is responsible forincubating the eggs.Clutch size varies with location: Northern Hemisphere birds lay more eggs than those in the Southern Hemisphere, and birds at higher latitudes have larger clutches than those closer to the equator. In central and northern Europe and Asia the clutch size is around 12, whereas it is around four in the tropics and seven in the subtropics. The eggs are round and milky blue when laid, but quickly discolour in the increasingly dirty nest.[15] They weigh 4.5 grams (0.16 oz).[23] A replacement clutch is possible.[19] When food is bountiful, the female will lay a few extra eggs for the purpose of providing food for chicks that have already hatched. In a study done in Spain, it was found that nests with a higher incidence of cannibalism successfully fledged more chicks than in nests where hatchlings weren't fed to older chicks.[27]
Hoopoes have well-developed anti-predator defences in the nest. Theuropygial gland of the incubating and brooding female is quickly modified to produce a foul-smelling liquid, and the glands of nestlings do so as well. These secretions are rubbed into the plumage. The secretion, which smells like rotting meat, is thought to help deter predators, as well as deter parasites and possibly act as an antibacterial agent.[28] The secretions stop soon before the young leave the nest.[23] From the age of six days, nestlings can also direct streams of faeces at intruders, and will hiss at them in a snake-like fashion.[15] The young also strike with their bill or with one wing.[23]
The incubation period for the species is between 15 and 18 days, during which time the male feeds the female. Incubation begins as soon as the first egg is laid, so the chicks are born asynchronously. The chicks hatch with a covering ofdowny feathers. By around day three to five, feather quills emerge which will become the adult feathers. The chicks are brooded by the female for between 9 and 14 days.[15] The female later joins the male in the task of bringing food.[24] The youngfledge in 26 to 29 days and remain with the parents for about a week more.[19]

The diet of the hoopoe includes many species considered by humans to bepests, such as the pupae of theprocessionary moth, a damaging forest pest which few other birds will eat because of its irritating hairs.[29] For this reason the species is afforded protection under the law in many countries.[15]
Hoopoes are distinctive birds and have made a cultural impact over much of their range. They were considered sacred inAncient Egypt, and were "depicted on the walls of tombs and temples".[citation needed] At the Old Kingdom, the hoopoe was used in the iconography as a symbolic code to indicate the child was the heir and successor of his father.[30] They achieved a similar standing inMinoan Crete.[23]
In theTorah,Leviticus 11:13–19,[31] hoopoes were listed among the animals that are detestable and should not be eaten. They are also listed inDeuteronomy as notkosher.[32]
The Hoopoe, known as thehudhud (هُدْهُد), also appears withKing Solomon in theQuran in Surah 27ٱلنَّمْلAl-Naml (The Ant):
27:20 ˹One day˺ he [Solomon] inspected the birds, and wondered, “Why is it that I cannot see the hoopoe? Or could he be absent?
27:21 I will surely subject him to a severe punishment, or ˹even˺ slaughter him, unless he brings me a compelling excuse.”
27:22 It was not long before the bird came and said, “I have found out something you do not know. I have just come to you from Sheba with sure news.
27:23 Indeed, I founda woman ruling over them, who has been given everything ˹she needs˺, and who has a magnificent throne.
27:24 I found her and her people prostrating to the sun instead of Allah. For Satan has made their deeds appealing to them—hindering them from the ˹Right˺ Way and leaving them unguided—
The connection of the hoopoe with Solomon and the Queen of Sheba in the Qur'anic tradition is mentioned in passing inRudyard Kipling'sJust So story "The Butterfly that Stamped".
In the pre-IslamicVainakh religion ofChechnya,Ingushetia andDagestan the hoopoe was sacred to the goddessTusholi and known as "Tusholi's hen". As her bird, it could only be hunted with the express permission of the goddess's high priest, and even then only for strictly medicinal purposes.[33]
Hoopoes were seen as a symbol of virtue inPersia. A hoopoe was a leader of the birds in the Persian book of poemsThe Conference of the Birds (Mantiq al-Tayr byAttar) and when the birds seek a king, the hoopoe points out that theSimurgh was the king of the birds.[34]
Hoopoes were thought of as thieves across much of Europe, and harbingers of war inScandinavia.[35] InEstonian tradition, hoopoes are strongly connected with death and theunderworld; their song is believed to foreshadow death for many people or cattle.[36] In medievalritual magic, the hoopoe was thought to be an evil bird. TheMunich Manual of Demonic Magic, a collection of magical spells compiled in Germany frequently requires thesacrifice of a hoopoe to summondemons and perform other magical intentions.[37]
Tereus, transformed into the hoopoe, is the king of the birds in theAncient Greek comedyThe Birds byAristophanes. InOvid'sMetamorphoses, book 6, KingTereus ofThrace rapesPhilomela, his wifeProcne's sister, and cuts out her tongue. In revenge, Procne kills their son Itys and serves him as a stew to his father. When Tereus sees the boy's head, which is served on a platter, he grabs a sword but just as he attempts to kill the sisters, they are turned into birds—Procne into aswallow and Philomela into anightingale. Tereus himself is turned into anepops (6.674), translated aslapwing by Dryden[38] andlappewincke (lappewinge) byJohn Gower in hisConfessio Amantis,[39] orhoopoe in A.S. Kline's translation.[40] The bird's crest indicates his royal status, and his long, sharp beak is a symbol of his violent nature. English translators and poets probably had thenorthern lapwing in mind, considering its crest.
The Eurasian hoopoe was chosen as thenational bird ofIsrael in May 2008 in conjunction with the country's 60th anniversary, following a national survey of 155,000 citizens, outpolling thewhite-spectacled bulbul.[41] The hoopoe appears on the logo of theUniversity of Johannesburg and is the official mascot of the university's sports teams. The municipalities ofArmstedt andBrechten, Germany, have a hoopoe in their coats of arms, as doesMārupe Municipality since 2021.
In Morocco, hoopoes are traded live and as medicinal products in the markets, primarily in herbalist shops. This trade is unregulated and a potential threat to local populations.[42]
InManipur, one of the states comprisingNortheast India, the hoopoe is still used by traditional Muslim healers in a variety of preparations believed locally to benefit a number of conditions both medical andspiritual.[43]Manipur abuts uponMyanmar and has been a cultural crossroads and melting pot of cultures for over 2,500 years.[44] Its traditional medicine may thus reflect influences from an unusually wide area, including not only theIndian subcontinent but alsoCentral Asia,Southeast Asia,East Asia and even the further-flung regions ofSiberia, theArctic,Micronesia andPolynesia.[45][46] Ibopishak and Bimola record four Manipurifolk medicinal uses of the hoopoe which specify neither the body part of the bird used nor its method of preparation:
More specifically, it is believed that if anessence (method of preparation unspecified) prepared from the bird is dropped into the eye, it will remove superfluouseyelashes andstrengthen the memory.[43]
Furthermore the authors record the following local Manipuri beliefs concerning specific body parts of the hoopoe:
While Ibopishak and Bimola are unable to find any discernible effect of hoopoe tissue alone upon the dissolution ofkidney stones, they do note that their experiments reveal that hoopoe tissue potentiates the effects of the Manipuri medicinal plantCissus javana, when employed to treat suchcalculi (local healers use bird and plant in just such a combination for this purpose). Since, however, there was nocontrol used involving the tissues of any other bird species, it remains unclear whether there are any medicinal properties peculiar to hoopoe tissue deriving from a distinctive chemistry.[43]
Harrison Tordoff, aWorld War IIfighter ace and later a noted ornithologist, named hisP-51 MustangUpupa epops, the scientific name of the hoopoe bird.[47]
A talking hoopoe named Almost Brilliant is a character inNghi Vo'sSinging Hills Cycle, first appearing inThe Empress of Salt and Fortune.[48]
