The green-striped brushfinch is a species of bird in the family Passerellidae. Until recently, it was placed in the genus Buarremon.
Region
Mexican Highlands
Typical Environment
Endemic to montane regions of central and southern Mexico, especially pine-oak and cloud forests with dense understory. It favors steep ravines, forest edges, and secondary thickets where leaf litter and low shrubs are abundant. The species is typically local but can be fairly common where suitable cover persists. It tends to remain within shaded, humid microsites near streams and gullies.
Altitude Range
1200–2600 m

The green-striped brushfinch is a shy, ground-oriented sparrow of dense montane understory, where it forages in pairs or small family groups. It was formerly placed in the genus Buarremon but is now included in Arremon based on vocal and genetic evidence. Its preference for thick brush and ravines makes it more often heard than seen. Conservation assessments consider it not at immediate risk, though local habitat loss can affect populations.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Usually encountered in pairs or small family groups, keeping low in dense cover. Nests are cup-shaped and placed close to the ground in thick vegetation. Territorial during the breeding season, with duets or countersinging between mates.
Migratory Pattern
Resident
Song Description
Song is a series of clear, thin whistles and short phrases delivered from a concealed perch. Calls include sharp chips and soft contact notes given while moving through brush.
Plumage
Olive-green upperparts with a contrasting patterned head; face grayish with dark lateral crown stripes and greenish crown streaks. Underparts are gray to whitish with a cleaner throat and often a subtle darker pectoral band. Wings and tail are dusky with olive edging; overall appearance is of a neat, brush-loving sparrow with crisp head striping.
Diet
Feeds on insects and other small invertebrates gleaned from leaf litter and low foliage. Also consumes seeds and small berries, especially outside the peak insect season. Foraging involves hopping, scratching, and flipping leaves to uncover prey.
Preferred Environment
Low, dense understory in pine-oak and cloud forests, along forest edges, ravines, and streamside thickets. Often forages on or near the ground under cover of shrubs and vines.
