The Hoopoe (Upupa epops) is a colourful bird that is found across Afro-Eurasia, notable for its distinctive 'crown' of feathers. It is the only extant species in the family Upupidae. One insular species, the Giant Hoopoe of Saint Helena, is extinct, and the Madagascar subspecies of the Hoopoe is sometimes elevated to a full species. The English name is derived from Latin upupa, which imitates the cry of the bird.
The Hoopoe is classified in the Coraciiformes clade, a group that also includes kingfishers, bee-eaters, rollers, and woodhoopoes (forming a clade with this one according to Hackett et al. (2008). A close relationship between the Hoopoe and the woodhoopoes is also supported by the shared and unique nature of their stapes. In the Sibley-Ahlquist taxonomy, the Hoopoe is separated from the Coraciiformes as a separate order, the Upupiformes. Some authorities place the woodhoopoes in the Upupiformes as well.
The fossil record of the hoopoes is very incomplete, with the earliest fossil coming from the Quaternary. The fossil record of their relatives is older, with fossil woodhoopoes dating back to the Miocene and those of an extinct related family, the Messelirrisoridae, dating from the Eocene.
It is the only extant member of its family, although some treatments consider some of the subspecies as separate species. Several authors have separated the Madagascan subspecies (U. e. marginata) as a separate species, and also the resident African form U. e. africana. The morphological differences between the most commonly split subspecies, U. e. marginata, and the other subspecies are minor, and only U. e. marginata has distinctly different vocalisations. One accepted separate species, the Giant Hoopoe, U. antaios, lived on the island of St Helena but became extinct in the sixteenth century, presumably due to introduced species.
The Hoopoe is a medium sized bird, 25–32 cm long, with a 44–48 cm wingspan weighing 46-89 g. 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.
The song is a trisyllabic "oop-oop-oop", which gives rise to its English and scientific names. 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 and hisses. A wheezy note is produced by females during courtship feeding by the male.
