Hemixos is a songbird genus in the bulbul family, Pycnonotidae. [1]
Established by Edward Blyth in 1845 for the newly discovered ashy bulbul (H. flavala), [2] this genus contains four extant species. [1]
Some treatments merge the genus into Hypsipetes , often together with the rest of the traditional "Hypsipetes group" of bulbuls: Iole , Ixos , Microscelis and Tricholestes . But in this case, the closely related genera Alophoixus and Setornis would probably also have to be included, and as soon as the earliest described genus, Ixos, is merged with another its name would apply. [3]
In fact, Hemixos is not particularly close to Hypsipetes, and a merger is not well justified. mtDNA NADH dehydrogenase subunits 2 and 3 and nDNA β-fibrinogen intron 7 sequence data puts it closer to (but still well distant from) the streaked bulbul (Ixos malaccensis). But whether that species represents the core group of Ixos– around its type species I. virescens (Sunda bulbul or green-winged bulbul) –, or a distinct lineage worthy of separation in a new genus – in which case Hypsipetes might be merged into the core group of Ixos– has not been studied. In any case, though minor, the Hemixos lineage with its stark white throat and light wing patches seems well distinct. [4]
Four species are currently recognised: [1]
Previously, some authorities also classified the following species (or subspecies) as species within the genus Hemixos:
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas.
The yellow-browed bulbul, or golden-browed bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in the forests of southern India and Sri Lanka. The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos.
The brown-eared bulbul is a medium-sized bulbul native to eastern Asia. It is extremely common within the northern parts of its range and can be found from southern Sakhalin to the northern Philippines.
The greenbuls are a group of birds within the bulbul family Pycnonotidae, found only within Africa. They are all largely drab olive-green above, and paler below, with few distinguishing features.
The ashy bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is found on the Indian subcontinent and in Southeast Asia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
Hypsipetes is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland.
The mountain bulbul is a songbird species in the bulbul family, Pycnonotidae. It is often placed in Hypsipetes, but seems to be closer to the type species of the genus Ixos, the Sunda bulbul. It is found in Southeast Asia and is not considered a threatened species by the IUCN. It is named after British East India Company Surgeon John McClelland.
The Nicobar bulbul is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Nicobar Islands.
The white-headed bulbul is a songbird species in the bulbul family, Pycnonotidae.
The Javan bulbul is a songbird species in the bulbul family. It is the type species of the genus Ixos. It is endemic to the island of Java in Indonesia in its natural habitat of subtropical or tropical moist montane forests. It is not considered a threatened species by the IUCN.
Ixos is a genus of passerine birds in the bulbul family, Pycnonotidae.
The streaked bulbul, or green-backed bulbul, is a songbird species in the bulbul family (Pycnonotidae). It is found on the Malay Peninsula, Sumatra, and Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is becoming rare due to habitat loss.
The sulphur-bellied bulbul is a songbird species in the bulbul family, Pycnonotidae. It is endemic to Palawan (Philippines). Its natural habitat is subtropical or tropical moist lowland forests. It is not considered a threatened species by the IUCN.
The Philippine bulbul is a songbird species in the bulbul family, Pycnonotidae.
The Zamboanga bulbulon de tintin is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Philippines, where its natural habitat is subtropical or tropical moist lowland forests of Basilan and the Zamboanga Peninsula. It is becoming rare due to habitat loss.
The streak-breasted bulbul is a songbird species in the bulbul family, Pycnonotidae.
The cream-striped bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is endemic to western Sumatra (Indonesia).
Iole is a genus of songbirds in the bulbul family, Pycnonotidae. They are native to tropical eastern Asia, from India to China and south through Southeast Asia to northern Indonesia.
Microscelis is a former genus of bulbuls.
The Mindoro bulbul is a songbird species in the bulbul family, Pycnonotidae.
