Black-breasted Thrush vs Black Thrush

Black-breasted Thrush

Turdus dissimilis

Medium75 gForest

The black-breasted thrush is 22 centimetres (8.7 in) to 23.5 centimetres (9.3 in) long in total, including its tail. Whereas the lower parts are the same colour for both sexes, the upper and middle parts are where they differ. For males, the section spanning from their head to the back of their neck and breast area is black, and the remaining areas at the top are slate gray. On the other hand, females are gray-brown from their eyes to their tail, and the section from their throat to their breast is a "diffused" shade of buff.

Black Thrush

Turdus infuscatus

Medium72 gForest

The black thrush is 22 to 23 cm (8.7 to 9.1 in) long and weighs about 60 to 90 g (2.1 to 3.2 oz). The species is sexually dimorphic. Adult males are almost entirely black with a slightly duller and more slaty belly and undertail coverts. They have a bright yellow ring of bare skin around the eye. Adult females have an olive brown head with dusky brown streaks on the cheeks and a dark brown eye ring. Their upperparts, tail, and upper surface of the wings are olive brown. Their chin and throat are whitish with dusky brown streaks on the latter. Voice: Black thrush males sing only in the breeding season. The species is "an accomplished singer with a rich vocal repertoire that includes mimicry of other cloud forest species". Its vocalizations have been compared to those of some mockingbirds. One description of the song is "a long, varied series of well-spaced, sweet clear whistled phrases: chaao-sit!-peer!-tleeet-pip'pip-peeeer!-seeet!-weeeer!
