Males are conspicuously yellow, while females have stronger dark streaks on the head and underside. At Brasília National Park, a breeding study found the finches using old mining sites and nesting close to the ground.
About 12 cm long. Males have yellow heads, breasts and underparts with dusky streaks above. Females are paler and more heavily streaked on the head and underside. White is visible on the outer tail feathers.
A 2007 study at Brasília National Park found 99 nests and identified old mining sites as frequently used breeding habitat in that study area. Nests were open cups about 30 cm above ground in ferns, shrubs or grass clumps.
An extinction-risk assessment has not been added yet.
