Habits, &c. This bird is found in pairs or small parties in forests. It is somewhat crepuscular according to Tickell, and during the day very sluggish. It has an oft-repeated mellow, rather musical note; also a clear whistle, which it utters when flying from tree to tree. The nest and eggs do not appear to have been recorded.
