The ruby-throated bulbul (Rubigula dispar), or yellow bulbul, is a member of the bulbul family of passerine birds. It is found on Sumatra, Java, and Bali.
Taxonomy and systematics
The ruby-throated bulbul was originally described in the genus Turdus and later moved to genus Pycnonotus. Pycnonotus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbul species, including the ruby-throated bulbul, moved to Rubigula. Until 2008, the ruby-throated bulbul was considered as conspecific with the black-capped, black-crested, flame-throated and Bornean bulbuls. Some authorities have considered the ruby-throated bulbul to be a subspecies of the black-capped bulbul.

It is virtually crestless, has a deep red throat and reddish eyes.
Distribution and habitat
This is a bird of forest and dense scrub.
