Ixos is a genus of passerine birds in the bulbul family, Pycnonotidae.
The genus Ixos was introduced in 1825 by the Dutch zoologist Coenraad Jacob Temminck to accommodate the Javan bulbul. [1] The genus name is the Ancient Greek for "mistletoe". [2]
Some authorities have advocated a complete merger of the genus Ixos with Hypsipetes– and even the entire "Hypsipetes group" of bulbuls, which also includes Hemixos , Iole and Tricholestes . Being the oldest genus name, Ixos would apply to all of them, rather than Hypsipetes as is often believed. [3] This re-classification seems hardly appropriate however, since Alophoixus and Setornis cannot be excluded from the "Hypsipetes group", and an all-out merge would turn the resultant "genus" Ixos into an ill-defined "wastebin taxon". The erroneous inclusion of I. virescens in Hypsipetes has caused the Nicobar bulbul to be listed under its invalid junior synonym H. nicobariensis rather than the valid names H. virescens or I. nicobariensis. [3]
There are five extant species in the genus Ixos: [4]
Formerly, some authorities also considered the following species (or subspecies) as species within the genus Ixos:
The red-whiskered bulbul, or crested bulbul, is a passerine bird native to Asia. It is a member of the bulbul family. It is a resident frugivore found mainly in tropical Asia. It has been introduced in many tropical areas of the world where populations have established themselves. It has a loud three or four note call, feeds on fruits and small insects and perches conspicuously on trees. It is common in hill forests and urban gardens.
The sombre greenbul is a member of the bulbul family of passerine birds. It is a resident breeder in coastal bush, evergreen forest and dry shrub land in eastern and southern Africa. It is the only member of the genus Andropadus.
The Seram golden bulbul is a species of songbird in the family Pycnonotidae. It is endemic to the Moluccas. Until recently, it was considered conspecific with the northern golden bulbul and the Buru golden bulbul. Its natural habitat is subtropical or tropical moist lowland forests.
Alophoixus is a genus of songbird in the bulbul family, Pycnonotidae found in south-eastern Asia.
The white-throated bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is found in south-eastern Asia from the eastern Himalayas to Myanmar and western Thailand. Its natural habitat is subtropical or tropical moist lowland forests.
The yellow-gorgeted greenbul, formerly known as the yellow-throated leaflove, is a species of passerine bird in the bulbul family Pycnonotidae. It is found in West Africa. Its natural habitats are subtropical or tropical dry forests, moist savanna, and subtropical or tropical moist shrubland.
Criniger is a genus of songbirds in the bulbul family, Pycnonotidae. The species of Criniger are found in western and central Africa.
The eastern bearded greenbul is a species of songbird in the bulbul family, Pycnonotidae. It is found from south-eastern Nigeria to Central African Republic, north-eastern Democratic Republic of the Congo, Congo and extreme north-western Angola. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
Hemixos is a songbird genus in the bulbul family, Pycnonotidae.
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 Nicobar bulbul is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Nicobar Islands. This species has sometimes been placed in the genus Ixos.
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.
The sooty-headed bulbul is a species of songbird in the Bulbul family, Pycnonotidae. It is found in south-eastern Asia. Its natural habitat is subtropical or tropical moist lowland forests.
Pycnonotus is a genus of frugivorous passerine birds in the bulbul family Pycnonotidae.
The scaly-breasted bulbul is a species of songbird in the bulbul family. It is found from the Malay Peninsula to Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The spot-necked bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is found in Sumatra. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. The spot-necked bulbul was originally described in the genus Ixos and later placed in Pycnonotus. Alternate names for the spot-necked bulbul include the olive-crowned bulbul, olive-necked bulbul and small white-streaked bulbul.
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.
The black-capped bulbul, or black-headed yellow bulbul, is a member of the bulbul family of passerine birds. It is endemic to Sri Lanka.
The dark-capped bulbul is a member of the bulbul family of passerine birds. It is found in central, eastern and south-eastern Africa.
The Cebu bulbul also known as the Cebu slaty-crowned bulbul or the Cebu streak-breasted bulbul is a subspecies of the streak-breasted bulbul. It is endemic to the Philippines found only on the island of Cebu where its natural habitat is tropical moist lowland forest. Thought extinct until its rediscovery in 1996, it is threatened by habitat loss and hunting. It is likely that this will eventually be split into a separate species and if so will become one of the most endangered species in the world.
