Small, plain-breasted thrush of highland forests, especially humid pine-oak. Feeds mainly on the ground, but also in fruiting bushes and trees. Sings from low to middle level perches, usually well hidden. More skulking than very similar Russet Nightingale-Thrush, but can be seen early and late in the day, hopping along the sides of quiet roads and paths. Slightly darker overall than Russet, with wholly pale orange underside of bill and plainer gray breast. Song distinctive: repeated fluty phrases, richer than Russet's song. Also compare with similar Orange-billed Nightingale-Thrush.
