Identification: Distinguished from all other thrushes in Singapore by light brown upperparts and white underparts with unique dense dark scales. Female Siberian Thrush is somewhat similar, but has contrasting white throat and supercilium, face, and a dark moustachial stripe, and lacks the dense upperpart scaling of this species. The White’s Thrush is also similar looking to many other thrushes from the same genus (Zoothera) that do not occur in Singapore; particular care is required to distinguish it from the near identical Scaly Thrush Z. dauma that has no records in Singapore but is also found in the region, albeit as a short-distance migrant. Scaly Thrush is comparatively weaker- and shorter-billed, but the most reliable method to distinguish the two species is by the wing formula, which is most easily determined in the hand. Excellent field photos may also be sufficient, as discussed here. In White's Thrush, the second-outermost primary (p2) is between the lengths of p4 and p5, while in Scaly Thrush p2 is shorter and between p5 and p6 instead.
