The Andean tit-spinetail (Leptasthenura andicola) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. == Taxonomy and systematics == The Andean tit-spinetail has these five subspecies: L. a. certhia (Madarász, G, 1903) L. a. extima Todd, 1916 L. a. exterior Todd, 1919 L. a. andicola Sclater, PL, 1870 L. a. peruviana Chapman, 1919 == Description == The Andean tit-spinetail is 15 to 17 cm (5.9 to 6.7 in) long and weighs about 15 to 16 g (0.53 to 0.56 oz). It is a small-bodied, long-tailed furnariid with a short bill. The sexes have the same plumage. Adults of the nominate subspecies L. a. andicola have a wide white supercilium on an otherwise dark streaky gray-brown face. Their crown is rich rufous chestnut with black streaks. Their upperparts are dark gray-brown with prominent white or whitish streaks. Their wings are dark brownish with faint rufescent edges on the coverts and flight feathers. Their tail's central pair of feathers are dusky brown to blackish ard are long and pointed, giving a forked appearance. The rest of the tail feathers are dusky brown to blackish with buffy outer webs. Their throat is white or whitish and their breast and belly are gray-brown with heavy white or whitish streaks that are more diffuse on the flanks and lower belly. Their iris is dark brown to reddish brown, their bill black with a slightly paler base to the mandible, and their legs and feet dark gray to black. Juveniles have little or no streaking on their crown, and their belly is mottled or scaly rather than streaked. Subspecies L. a. extima is smaller than the nominate, with a narrower and buffier supercilium, paler crown streaks, bright cinnamon brown edges on the wing coverts, much cinnamon rufous on the flight feathers, and a buffier brown belly. L. a. certhia has a whiter supercilium than extima, with lighter crown streaks, smaller cinnamon edges on the wing coverts and flight feathers, a whiter throat and breast, and grayer underparts. L. a. exterior compared to extima has a brighter black-streaked rufous crown, wider white streaks on the back, a whiter throat, and a less brownish belly. L. a. peruviana compared to the nominate has a less streaky face, a paler crown with narrower black streaks, paler edges on the wing coverts, wider buff edges on the flight feathers, and a darker breast and belly.
