The tawny tit-spinetail (Sylviorthorhynchus yanacensis) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, and Peru. The tawny tit-spinetail was first placed in genus Leptasthenura but genetic data published in 2011 places it firmly in genus Sylviorthorhynchus.

The tawny tit-spinetail is monotypic. However, the Peruvian and Bolivian populations have some plumage differences and there is speculation that they may represent different taxa. The tawny tit-spinetail is 16 to 17.5 cm (6.3 to 6.9 in) long and weighs 10 to 12 g (0.35 to 0.42 oz). The sexes have the same plumage. Adults have a mostly bright cinnamon buff face with a tawny rufous forehead and a tawny brown crown. The Peruvian poplulation has a narrow buff supercilium while that of Bolivian birds is whitish. Their back is tawny brown and their rump and uppertail coverts are rufous. Their wing coverts are dusky with rufous edges and their flight feathers are dusky brown with much rufous on their outer webs. Their tail... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Tawny Tit-Spinetail is recorded against all the birds logged in La Paz (6 verified sightings), 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.
