Turdus subalaris
The blacksmith thrush is 20 to 22.5 cm (7.9 to 8.9 in) long and weighs 46 to 55 g (1.6 to 1.9 oz). The species is sexually dimorphic. Adult males have a mostly gray head with an orange-yellow to brown eye-ring and a black-streaked white throat. Their upperparts, wings, and tail are gray. Their breast is a lighter gray and their belly and vent white. They have a dark brown iris. Their bill is orange-yellow to brown with orange-yellow patches and their legs and feet yellowish brown to brownish gray. Voice: The blacksmith thrush's song is a "short series of 2-6 descending, weak, squeaky notes, give at 5- to 6-second intervals, like twee sri-sri-sri or tur-rit-twee-twee-twee". Its call is a "high, slightly upslurred tweet".

Turdus reevei
The plumbeous-backed thrush is 23 to 24 cm (9.1 to 9.4 in) long and weighs 61 to 66 g (2.2 to 2.3 oz). The sexes have almost the same plumage. Adult males have a mostly bluish slate-gray head with a dark-streaked white throat. Female's heads are slightly browner. Both sexes have bluish slate-gray upperparts, wings, and tail. They have a white crescent below the streaked throat, a pale gray breast that becomes white on the belly and vent, and an orange-buff wash on the flanks. Both sexes have a white to bluish white iris, a pale yellow bill, and pale yellow legs and feet. Voice: The plumbeous-backed thrush appears to sing only during the breeding season. Its song is "a fairly fast, typical Turdus caroling". Its most common call is "an abrupt and piercing, descending pseeeu". Other calls include "a ringing tseeet" and "a wheezy, rising rheet".
