HABITAT Undergrowth in bamboo, lowland clearings, and hillside scrub generally to 1,200’- 4,500’ elevation. CONSERVATION STATUS IUCN: Least Concern (2016). Population Trend: Stable. COOL FACTS The collared finchbill gets its name from the appearance of a white collar around its neck, and its thicker, finch-like bill. It is not classified as a finch. Its “generalist” type of beak allows it to feed on a wide variety of food items: hard seed, as well as insects and fruit. It is thin-skinned and will shed feathers readily when handled. This bird is a member of a family of birds known as bulbuls. Bulbuls are a group of approximately 130 species of medium-sized songbirds inhabiting Africa, the Middle East, through Asia, and Indonesia. MEDIAN LIFE EXPECTANCY Unknown.
