Male has rufescent-olive upperparts, including crown and ear-coverts, and grey underparts becoming paler on belly and vent. Female has white throat and whiter centre to breast and belly, some dark spots/streaks on sides of throat and upper breast and warm brownish fringes to breast feathers.The grey-sided thrush forages for insects and berries on the ground or less commonly in the trees, often in the company of the eyebrowed thrush (Turdus obscurus).
