Zamboanga bulbul

The Zamboanga bulbul (Hypsipetes rufigularis) is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Philippines, where its natural habitat is subtropical or tropical moist lowland forests of Basilan and the Zamboanga Peninsula. It is becoming rare due to habitat loss.

Taxonomy and systematics
The Zamboanga bulbul was originally described in the genus Hypsipetes and later placed in the genus Ixos. Formerly, some authorities classified the Zamboanga bulbul in the genus Iole and also considered it to be a subspecies of the Philippine bulbul. In 2010, it was returned to the genus Hypsipetes.
