Endangered
Streak-breasted bulbul
Hypsipetes siquijorensis
The streak-breasted bulbul is a songbird species in the bulbul family, Pycnonotidae.
Appearance
The other two subspecies have much lighter colored appearances and no spiky crown.The streak-breasted bulbul was originally described in the genus Iole and later placed in the genus Ixos before being re-classified to the genus Hypsipetes in 2010. Alternate names for the streak-breasted bulbul include the mottle-breasted bulbul and slaty-crowned bulbul.
Range and habitat
It is endemic to the Philippines found in the Visayas on the islands of Tablas Island, Siquijor, Cebu and Romblon. Its natural habitat is tropical moist lowland forest and tropical moist shrubland. 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.
Siquijor, Cebu and Tablas Island are some of the most deforested islands with just 8 km2 of forest remaining on Siquijor and 15km2 on Cebu.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Not much information of its diet in the wild. The other two subspecies are believed to feed on fruits and berries but diet has yet to be studied.
In crisis
It is currently an endangered species. If split into three species, the Cebu bulbul and Romblon bulbul are likely critically endangered. It is threatened by habitat loss and hunting.
IUCN has assessed this bird as endangered with population estimates being 2,500 to 9,999 mature individuals and continuing to decrease. Although it can tolerate less than ideal forest, this species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range.
