The line-fronted canastero (Asthenes urubambensis) is a Near Threatened species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia and Peru.
Taxonomy and systematics
The line-fronted canastero has two subspecies, the nominate A. u. urubambensis (Chapman, 1919) and A. u. huallagae (Zimmer 1924).
Description
The line-fronted canastero is 17 to 18 cm (6.7 to 7.1 in) long and weighs 16 to 20 g (0.56 to 0.71 oz). It is a large canastero with a narrow spiny tail. The sexes have the same plumage. Adults of the nominate subspecies have a conspicuous whitish supercilium that widens past the eye on an otherwise light brownish face with narrow dark brown streaks. Their forehead ("front") is dark brown with well-defined golden-brown stripes that fade on the brown crown.
This brief starts where responsible research should: with the source description of “Line-fronted canastero” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q1270607. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1919 and 1924.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
