Namesake sky-blue patch, which extends from the upper nape to the back of the crown, can be difficult to see. Inhabits lowland and foothill forests and other wooded areas, often on small offshore islands. Forages in flocks, screeching loudly to one another to stay in contact. Native to the Philippines and small offshore islands in Malaysia; feral population established in Kota Kinabalu. Declining across much of its range, and extirpated in some areas.
