Upupa epops (Ramat Gan)002.jpg

The Eurasian hoopoe (''Upupa epops'') is the most widespread species of the genus ''Upupa''. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop". It is native to Europe, Asia and the northern half of Africa. It is migratory in the northern part of its range. It spends most of the time on the ground probing for grubs and insects. The clutch of seven to eight eggs is laid in an existing cavity. The eggs are incubated by the female and hatch asynchronously. Some ornithologists treat the African and Madagascar hoopoes as subspecies of the Eurasian hoopoe.

Taxonomy

The Eurasian hoopoe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his '' Systema Naturae''. He cited the earlier descriptions by the French naturalist Pierre Belon and by the Swiss naturalist Conrad Gessner, both of which had been published in 1555. Linnaeus placed the Eurasian hoopoe with the northern bald ibis and the red-billed chough in the genus ''Upupa'' and coined the binomial name ''Upupa epops''. The specific epithet ''epops'' in the Ancient Greek word for a hoopoe.

Subspecies

Nine subspecies of Eurasian hoopoe are recognised by Krištín (in the 2001 ''Handbook of the Birds of the World''). They vary mostly in size and the depth of colour in the plumage. A further subspecies has been proposed: ''U. e. orientalis'' in northwestern India.

Description

The Eurasian hoopoe is a medium-sized bird, long, with a wingspan. It weighs . The species is highly distinctive, with a long, thin tapering beak, bill that is black with a fawn base. The strengthened muscle, musculature of the head allows the bill to be opened when probing inside the soil. The hoopoe has broad and rounded wings capable of strong flight; these are larger in the northern bird migration, migratory subspecies. The hoopoe has a characteristic undulating bird flight, flight, which is like that of a giant butterfly, caused by the wings half closing at the end of each beat or short sequence of beats. Adults may begin their moult after the breeding season and continue after they have migrated for the winter.

The call is typically a trisyllabic ''oop-oop-oop'', which may give rise to its English and scientific names, although two and four syllables are also common. An alternative explanation of the English and scientific names is that they are derived from the French name for the bird, ''huppée'', which means crested. In the Himalayas, the calls can be confused with that of the Himalayan cuckoo (''Cuculus saturatus''), although the cuckoo typically produces four notes. Other calls include rasping croaks, when alarmed, and hisses. Females produce a wheezy note during courtship feeding by the male.

Distribution and habitat

The Eurasian hoopoe is widespread in Europe, Asia, and North Africa and northern Sub-Saharan Africa. Most European and north Asian birds bird migration, migrate to the tropics in winter. Those breeding in Europe usually migrate to the Sahel belt of sub-Saharan Africa. The birds predominantly migrate at night. In contrast, the African populations are sedentary all year. The species has been a vagrancy (biology), vagrant in Alaska; ''U. e. saturata'' was recorded there in 1975 in the Yukon Delta. Hoopoes have been known to breed north of their European range, and in southern England during warm, dry summers that provide plenty of grasshoppers and similar insects, although as of the early 1980s northern European populations were reported to be in the decline, possibly due to changes in climate. In 2015, a record numbers of hoopoes were recorded in Ireland, with at least 50 birds recorded in the southwest of the country. This was the highest recorded number since 1965 when 65 individuals were sighted.

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) 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 Heath, heathland, wooded steppes, Savanna, savannas and Grassland, grasslands, as well as forest glades.

Hoopoes make seasonal movements in response to rain in some regions such as in Ceylon and in the Western Ghats. Birds have been seen at high altitudes during migration across the Himalayas. One was recorded at about by the first Mount Everest expedition.

Behaviour and ecology

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. They also enjoy taking dust and sand baths.

Food and feeding

The diet of the Eurasian hoopoe is mostly composed of insects, although small reptiles, frogs and plant matter such as Seed, seeds and Berry, 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 manoeuvrable, in pursuit of numerous swarming Insect, 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, Pupa, 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 Cricket (insect), crickets, Locust, locusts, Beetle, beetles, Earwig, earwigs, Cicada, cicadas, Antlion, ant lions, bugs and ants. These can range from in length, with a preferred prey size of around . 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.

Breeding

The hoopoe genus is monogamy, monogamous, although the pair bond apparently only lasts for a single season, and territory (animal), territorial. 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. Birds will try to stab rivals with their bills, and individuals are occasionally blinded in fights. The nest is in a hole in a tree or wall, and has a narrow entrance. It may be unlined, or various scraps may be collected. The female alone is responsible for avian incubation, incubating the eggs. avian clutch size, 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. They weigh . A replacement clutch is possible.

The Egg incubation, 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 of Down feather, downy 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. The female later joins the male in the task of bringing food. The young fledge in 26 to 29 days and remain with the parents for about a week more. Hoopoes show hatching asynchrony of eggs which is thought to allow for brood reduction when food availability is low.

Hoopoes have well-developed anti-predator defences in the nest. The uropygial 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. The secretions stop soon before the young leave the nest. 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. The young also strike with their bill or with one wing.

Relationship with humans

The diet of the Eurasian hoopoe includes many species considered by humans to be Pest (organism), pests, such as the pupae of the Thaumetopoea pityocampa, processionary moth, a damaging forest pest. For this reason the species is afforded protection under the law in many countries.

Hoopoes are distinctive birds and have made a cultural impact over much of their range. They were considered sacred in Ancient Egypt, and were "depicted on the walls of tombs and temples". During 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. They achieved a similar standing in Minoan Crete.

In the Torah, Leviticus 11:13–19, hoopoes were listed among the animals that are detestable and should not be eaten. They are also listed in Deuteronomy 14:18 as not kosher.

The hoopoe also appears in the Quran and is known as the "Hudhud (mythology), Hudhud" (wikt:هدهد, هدهد), in Surah Al-Naml 27:20–22: "And he King Solomon, Solomon sought among the birds and said: How is it that I see not the hoopoe, or is he among the absent? (20) I verily will punish him with hard punishment or I verily will slay him, or he verily shall bring me a plain excuse. (21) But he [the hoopoe] was not long in coming, and he said: I have found out (a thing) that thou apprehendest not, and I come unto thee from Queen of Sheba, Sheba with sure tidings."

Hoopoes were seen as a symbol of virtue in Persia. A hoopoe was a leader of the birds in the Persian book of poems ''The Conference of the Birds'' ("Mantiq al-Tayr" by Attar of Nishapur, Attar) and when the birds seek a king, the hoopoe points out that the Simurgh was the king of the birds.

Hoopoes were thought of as thieves across much of Europe, and harbingers of war in Scandinavia. In Estonian tradition, hoopoes are strongly connected with death and the underworld; their song is believed to foreshadow death for many people or cattle.

The hoopoe is the king of the birds in the Ancient Greek comedy ''The Birds (play), The Birds'' by Aristophanes. In Ovid's ''Metamorphoses'', book 6, King Tereus of Thrace rapes Philomela, his wife Procne'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 a swallow and Philomela into a nightingale. Tereus himself is turned into an ''epops'' (6.674), translated as ''lapwing'' by Dryden and ''lappewincke'' (''lappewinge'') by John Gower in his ''Confessio Amantis'', or ''hoopoe'' in A. S. Kline's translation. 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 the northern lapwing in mind, considering its crest.

The hoopoe was chosen as the national bird of Israel in May 2008 in conjunction with the country's 60th anniversary, following a national survey of 155,000 citizens, outpolling the white-spectacled bulbul. The hoopoe appears on the Logo of the University of Johannesburg and is the official mascot of the University's sports. The municipalities of Armstedt and :de:Brechten, Brechten, Germany, have hoopoes in their coats of arms.

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

Three CGI enhanced hoopoes, together with other birds collectively named "the tittifers", are often shown whistling a song in the BBC children's television series ''In the Night Garden...''.

Conservation

The Eurasian Hoopoe is listed as a species of "Least concern" by the IUCN. Despite the fact, the species has been in a continuous decline according to the organisation since 2008, the causes being loss of habitat and over-hunting.

Hunting is of concern in southern Europe and Asia.

In Europe, the hoopoe seems to have a stable population though it is threatened in several regions. The bird is considered extinct in Sweden and "needing active conservation" in Poland. The species has recovered and stabilised in Switzerland, however they remain vulnerable.
