Fairly common in its range, Yellow-throated Bush-Tanager occurs in humid forest on both Andean slopes. They inhabit the foothills and subtropical forest, where they prefer the understory near streams. They seem to especially favor ravines. Although generally in single-species groups, they occasionally join mixed flocks. Compared to other bush-tanagers, they are fairly large. Note also the dark iris and grayish chest with yellow limited to the throat. Birds occurring in the eastern Andes (subspecies C. f. flavigularis) have a very gray chest, whereas birds of the western Andean subspecies (C. f. marginatus) are more dingy gray-brown below. Flocks are generally quite noisy, giving a variety of high chips and short trills.
