Коричневоспинная диука Idiopsar dorsalis

Handsome “finch” that is actually a tanager; found very locally on bogs and rocky slopes of the high Andes. Usually in pairs (sexes look similar) or small groups, feeding quietly on the ground and not associating with other seed-eating birds. Contrasting bright rusty back is diagnostic, but seen only from the front can look very similar to White-throated Sierra-Finch. Immature has duller rusty back with vague dark streaking.
