Creamy-bellied Thrush
Turdus amaurochalinus
The creamy-bellied thrush is 22 to 25 cm (8.7 to 9.8 in) long and weighs 52 to 73 g (1.8 to 2.6 oz). The sexes have the same plumage. Adults have a mostly olive-brown head with black lores and a brown-streaked white throat. Their upperparts, wings, and tail are the same olive-brown as the head. Their breast and flanks are usually grayish buff that becomes creamy white on the belly and undertail coverts. (Some individuals have pure gray instead of grayish buff underparts.) They have a dark iris, a yellowish bill when breeding and a darker one otherwise, and drab brown legs and feet. Voice: The creamy-bellied thrush's song is a "simple, little varied, yet musical series with short notes, like tjurre, wurr, tjeeh, and tjut-tjeé". Its calls include a "sharp pok", a "psiip in or before flight", and as a warning a "sharp kitten-like pchuo".

Great Thrush
Turdus fuscater
Adults are 28 to 33 cm (11 to 13 in) in length and weigh 128 to 175 g (4.5 to 6.2 oz), averaging 141 g (5.0 oz), making the species the largest member of the wide-ranging Turdus genus, and one of the largest thrushes although the Amami thrush may match or exceed it in size. It can be easily identified by its yellowish-orange beak and legs and yellow ring around the eye. Slight sexual dimorphism is sometimes present, with males having more strongly coloured legs and eye rings. Tail feathers are long. The plumage is black-brown, darker on wings and tail and pale on the belly.
