Lesser woodcreeper
species of bird

The lesser woodcreeper (Xiphorhynchus fuscus) is a species of bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Paraguay.
Taxonomy and systematics
The lesser woodcreeper was originally placed in genus Lepidocolaptes but has been in its current assignment since the late 1990s. It has three subspecies, the nominate X. f. fuscus (Vieillot, 1818), X. f. pintoi (Longmore & Silveira, 2005), and X. f. tenuirostris (Lichtenstein, MHC, 1820). Subspecies X. f. pintoi had previously been known as Lepidocolaptes fuscus brevirostris but the subspecies epithet was changed upon the move to genus Xiphorynchus because of the principle of priority.
What is now the Ceara woodcreeper (X. atlanticus, also called Atlantic woodcreeper) was until the 2010s also considered a subspecies of the lesser woodcreeper.
This brief starts where responsible research should: with the source description of “Lesser woodcreeper” 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 19, 2026. The linked authority identifier is Q910301. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1818, 2005 and 1820.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
