A medium-sized thrushlike bird of dense forests and undergrowth. The reddish brown coloration and white spectacles are distinctive. Usually skulks in dense vegetation, but may sing from an exposed perch or forage out in the open during dawn and dusk. Usually observed singly or in pairs. The song is loud, long, and varied, involving mimicry of other birds, whistles, and harsh notes that are often repeated. Introduced to Taiwan, Japan, and the Hawaiian Islands.
