:"Hypsipetes virescens" ''redirects here. This may also (erroneously) refer to the Sunda bulbul (''Ixos virescens''); see below for details.'' Found only on the Nicobar Islands of India, the Nicobar bulbul is a songbird species in the bulbul family (Pycnonotidae). Its scientific name is ''Ixos virescens'' as long as ''Ixos'' is recognized as a distinct genus.〔Gregory (2000)〕 Some sources merge ''Ixos'' into ''Hypsipetes'', probably based on the major taxonomic error committed in the Sibley taxonomy, where ''I. virescens'' – the type species of ''Ixos'' – was placed in ''Hypsipetes''.
