The buff-throated warbling finch is a species of bird in the family Thraupidae. It is found in forest borders and woodland in south-eastern Brazil. It was previously considered conspecific with the gray-throated warbling finch, and together they were known as the red-rumped warbling finch. The SACC found enough evidence to split them in 2009.
Region
Atlantic Forest (Southeast Brazil)
Typical Environment
This species inhabits the Atlantic Forest belt of southeastern Brazil, especially along forest borders, secondary woodlands, and shrubby clearings. It frequents montane and foothill zones with dense understory, bamboo clumps, and regenerating patches. Individuals often move along the mid-story and edge tangles, occasionally descending to the ground to forage. It tolerates moderately disturbed habitats but remains most common near continuous forest. It is typically encountered in pairs or small groups and joins mixed flocks.

Ease of Keeping
Beginner friendly: 2/5
A small tanager of Brazil’s Atlantic Forest, the buff-throated warbling finch favors forest edges and secondary growth. It was formerly lumped with the gray-throated warbling finch as the red-rumped warbling finch before being split in 2009. Often accompanying mixed-species flocks, it helps control insect populations while dispersing seeds from small fruits.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found in pairs or small family groups, it readily joins mixed-species flocks moving along forest edges. Nests are typically placed low to mid-level in dense vegetation. During the breeding season, pairs defend small areas around nest sites but remain loosely associated with nearby conspecifics.
Migratory Pattern
Resident
Song Description
A bright, warbling series of clear notes and trills delivered in short phrases. Calls include thin chips and soft contact notes used while moving through foliage.
Plumage
Compact finch-like bird with a gray head and nape, warm olive-brown upperparts, and a contrasting buffy throat blending into a paler breast and belly. The rump shows rich rufous tones, especially noticeable in flight. Wings and tail are dusky with subtle edging; underparts are lighter with a buff wash on the throat and upper breast.
Diet
Feeds on a mix of small seeds, berries, and arthropods such as beetles and caterpillars. It picks items from leaves and twigs, and occasionally gleans from the ground. Seasonal fruit availability supplements a largely seed- and insect-based diet. In mixed flocks it often forages at mid-levels, benefiting from group vigilance.
Preferred Environment
Forages along forest edges, regenerating secondary growth, bamboo stands, and shrub-laden clearings. It uses tangles and low to mid-story foliage, moving methodically through cover.
