The Red-legged Thrush has blue-grey to slate-grey upperparts and bright reddish-orange legs. Its plumage varies among islands, and some subspecies have conspicuous white tail tips.
At Baconao’s coastal scrub, Red-legged Thrush nests were large and made mainly from leaves, twigs, tendrils and bark. Small cloth fragments and Tillandsia plants were also used. Nests stood 1.2–2.8 m above ground; those seen from April to June held three to five reddish-white eggs with brown spots.
