Ixos is a paraphyletic songbird genus in the bulbul family, Pycnonotidae.
Taxonomy and systematics
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.[1] 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.[1]
Extant species
There are four extant species in the genus Ixos:[2]
- Nicobar bulbul (Ixos nicobariensis)
- Mountain bulbul (Ixos mcclellandii)
- Streaked bulbul (Ixos malaccensis)
- Sunda bulbul (Ixos virescens) (the type species)
Former species
Formerly, some authorities also considered the following species (or subspecies) as species within the genus Ixos:
- Cream-striped bulbul (as Ixos leucogrammicus)[3]
- Spot-necked bulbul (as Ixos tympanistrigus)[4]
- Grey-headed bulbul (as Ixos Fisquetti)[5]

- Red-whiskered bulbul (pyrrhotis) (as Ixos pyrrhotis)[7]
- Red-whiskered bulbul (emeria) (as Ixos emeria)[8]
- Chinese red-whiskered bulbul (as Ixos monticola)[9]
- Brown-breasted bulbul (andersoni) (as Ixus Andersoni)[10]
- Light-vented bulbul (hainanus) (as Ixus hainanus)[11]
- White-eared bulbul (as Ixos leucotis)[12]
- Sooty-headed bulbul (germani) (as Ixus Germani)[13]
- White-spectacled bulbul (as Ixus xanthopygos)[14]
- Upper Guinea bulbul (as Ixos inornatus)[15]
- Dark-capped bulbul (as Ixos tricolor)[16]
- Pale-eyed bulbul (as Ixus Davisoni)[17]
