The Sula golden bulbul (Hypsipetes longirostris) is a species of songbird in the bulbul family Pycnonotidae. It is endemic to Sula Island (east of Sulawesi) in the Philippines. Its natural habitat is subtropical or tropical moist lowland forests.
The Sula golden bulbul was originally classified in the genus Criniger, and has also been classified in the genus Alophoixus. The Sula golden bulbul was formerly considered as conspecific with five other bulbuls, all called the northern golden bulbul before they were all split.[1] [2]
