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 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.

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 →
