The streak-breasted bulbul (Hypsipetes siquijorensis) is a songbird species in the bulbul family, Pycnonotidae.
It is endemic to the Philippines found in the Visayas on the islands of Tablas Island, Siquijor, Cebu and Romblon. This species is believed to be a species complex and its three subspecies are all distinct species namely the Cebu bulbul, Tablas bulbul and the Siquijor bulbul. Its natural habitat is tropical moist lowland forest and tropical moist shrubland.
It is currently an endangered species. If split into three species, the Cebu bulbul and Romblon bulbul are likely critically endangered. Thought extinct until its rediscovery on 1996, the Cebu bulbul in particular is especially at risk of extinction as unlike the other subspecies, is a forest specialist and cannot survive in scrubland. It is threatened by habitat loss and hunting.
