Up until recently this species included the Tepui Redstart (Myioborus castaneocapillus) due to rather similar plumage patterns, although their distributions are quite distant from each other. Molecular data confirms that the smaller Brown-capped Redstart is actually quite distantly related to the Tepui Redstart. The Brown-capped Redstart is in fact the southernmost of the “whitestart” group, the genus Myioborus and it is restricted to western Argentina and Bolivia. It is found in montane forests, from relatively dry to moist forests in fact. It also has an isolated distribution in Argentina, around the isolated mountains in Cordoba. It is a conspicuous member of the Yungas forest bird community in Argentina, and relatively common in that country. It’s song is a high sibilant trill, suggestive of a Tropical Parula (Parula pitiayumi), although it is a steady trill, not one that changes in pitch or is accented at the end as in the parula. When foraging, the Brown-capped Redstart typically flares the extensive white on its tail, and flicks the tail up nervously. This restart is a rather attractive bird, yellow below, grey faced and showing a warm chestnut cap; the back is greenish, while the wings and central tail feathers are slaty-gray. The face is highlighted by white eye crescents around a dark eye.
