The Eurasian hoopoe or common 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".
The Eurasian hoopoe is native to Europe, Asia and Africa. It is migratory in the northern part of its range. Some ornithologists consider the Madagascar hoopoes as a subspecies. The African hoopoe, subspecies U. e. africana, has sometimes been treated as a separate species.
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.
The muscles of the head allow the hoopoe's bill to be opened when it is inserted into the ground
The Eurasian hoopoe is a medium-sized bird, 25–32 cm (9.8–12.6 in) long, with a 44–48 cm (17–19 in) wingspan. It weighs 46–89 g (1.6–3.1 oz).[8] The species is highly distinctive, with a long, thin tapering bill that is black with a fawn base. The strengthened 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 migratory subspecies. The hoopoe has a characteristic undulating 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.
The Eurasian hoopoe is widespread in Europe, Asia, and North Africa and northern Sub-Saharan Africa. Most European and north Asian birds 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 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 heathland, wooded steppes, savannas and 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 6,400 m (21,000 ft) by the first Mount Everest expedition.
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.
