"IUCN3.1" . . . . . . "The grey-cheeked thrush (Catharus minimus) is a medium-sized thrush. This species is 15\u201317 cm in length, and has the white-dark-white underwing pattern characteristic of Catharus thrushes. It is a member of a close-knit group of migrant species together with the veery and Bicknell's thrush; it forms a cryptic species pair with the latter. The grey-cheeked thrush is all but indistinguishable from Bicknell's thrush except by its slightly larger size and different song."@en . "Grey-cheeked thrush"@en . "LC" . . . . .
