Styan's Bulbul

Styan's bulbul is a species of bulbul that is endemic to eastern and southern Taiwan. Though locally common in some areas, it has been listed as a species vulnerable to extinction. Its decline has been caused by habitat destruction and hybridisation with the closely related Chinese or light-vented bulbul. The two species' ranges overlap in several areas, partly because birds of the latter species have been released for Buddhist ceremonies. The species has already become extinct in Yilan County (Taiwan).
