The white-chinned thistletail, or colicardo barbiblanco in Ecuador, (Asthenes fuliginosa) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Colombia, Ecuador, Peru, and Venezuela.

What are now several other individual species of thistletail were previously also treated as subspecies of the white-chinned thistletail. All of them were in genus Schizoeaca but genetic data showed that the genus is embedded within Asthenes. In addition, the mouse-colored thistletail (A. griseomurina) possibly should be treated as a fifth subspecies of the white-chinned.
The white-chinned thistletail is 18 to 20 cm (7.1 to 7.9 in) long and weighs 14 to 20 g (0.49 to 0.71 oz). It is the largest thistletail. The sexes have the same plumage.

GBIF citizen-science records
It is estimated from how often the White-chinned Thistletail is recorded against all the birds logged in Chingaza National Natural Park (325 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
