The Sunda bulbul (Ixos virescens) is a songbird species in the bulbul family. It is the type species of the genus Ixos. It is endemic to Indonesia where it occurs on Sumatra and Java in its natural habitat of subtropical or tropical moist montane forests. It is not considered a threatened species by the IUCN.
Taxonomy and systematics
The Sunda bulbul is sometimes classified in the genus Hypsipetes, presumably based on an earlier error in the Sibley taxonomy. The specific epithet virescens was given to the present species by Coenraad Jacob Temminck in 1825 and pre-dates the same name as given to the Nicobar bulbul by Edward Blyth in 1845. The olive bulbul has also been given the same scientific binomial, Hypsipetes virescens. Alternate names for the Sunda bulbul include the green mountain bulbul, green-backed bulbul, green-winged bulbul, rufous-bellied bulbul, streaked bulbul and streaked mountain bulbul. The name 'streaked bulbul' should not be confused with the species of the same name, Ixos malaccensis.
Two subspecies are currently recognized:
- Sumatran bulbul (I. v. sumatranus) - (Wardlaw-Ramsay, 1882): Originally described as a separate species in the genus Hemixus. Found in western Sumatra
- Javan Bulbul (I. v. virescens) - Temminck, 1825: Also named the Javan streaked bulbul. Found on Java
