The Zamboanga bulbul is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Philippines, where its natural habitat is tropical moist lowland forests of Basilan and the Zamboanga Peninsula. It is becoming rare due to habitat loss.
Region
Mindanao region, southern Philippines
Typical Environment
It inhabits tropical moist lowland and foothill evergreen forests, using both primary and well-structured secondary growth. The species favors the midstory to canopy, often along forest edges, ridges, and riparian corridors with dense cover. It can persist in selectively logged forest and regenerating areas if fruiting trees remain, but it avoids heavily degraded or open habitats. Local occurrence is patchy, tracking fruit availability and intact forest patches.

The Zamboanga bulbul is a forest songbird endemic to the southern Philippines, historically treated as part of the Philippine bulbul complex but now recognized as a distinct species. It plays an important role as a seed disperser for native trees and also consumes insects, helping control forest pests. It is shy and most often detected by its clear, whistled calls from the midstory and canopy. Ongoing deforestation in Basilan and the Zamboanga Peninsula is the main threat to its persistence.

Temperament
