The Bearded Tachuri is a Near Threatened species that has a very local and disjunct distribution primarily across eastern South America. A very small population (perhaps now extinct) is known from the Andes of Colombia, but the main range is in the savannas of the Guianan Shield, and thereafter in central-south Brazil, Paraguay, southern Uruguay, and eastern Bolivia (where it is again possibly extinct). Further south, the Bearded Tachuri is an austral summer visitor to central-east Argentina. Three subspecies have been named. Virtually everywhere this attractive bird appears to be in decline, especially in southern Brazil, the result of conversion of native grasslands to agriculture. Males have a largely black head, with a white stripe in front of the eye, rufous underparts, and largely brown upperparts. Females lack the black feathering on the head, but do possess a pale supercilium.
