Rufous-capped antthrush
species of bird

The rufous-capped antthrush (Formicarius colma) is a small species of bird in the family Formicariidae located in the order Passeriformes.
It is considered to be uncommon but widespread, found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.
The rufous-capped antthrush is typically found inhabiting the shady floor of tall, humid forests on solid ground, and is occasionally spotted in transitional forests (várzea) and savanna forests (Suriname).
Taxonomy and systematics
The rufous-capped antthrush was first described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his 1779 journal Histoire Naturelle des Oiseaux (Natural History, General and Particular, with a Description of the King's Cabinet) from a specimen collected in Cayenne, French Guiana and was further engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle (Illuminated Planks of Natural History) which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither Buffon's description nor Martinet's drawing included a scientific name, however, Dutch naturalist Pieter Boddaert coined the binomial name Formicarius colma (Formicarius being Latin for "of the ant") in his 1783 catalogue the Planches Enluminées, with the specific epithet colma forged by Buffon, most likely being a contraction of "collier" (necklace) and "marque" (mark).
There are four recognized subspecies of Formicarius:
F. c. colma (Boddaert, 1783) – found in east Colombia, south Venezuela, the Guianas and north Brazil (north of the Amazon);
F. c. nigrifrons (Gould, 1855) – found in east Ecuador, east Peru, north Bolivia and southwest Amazonian Brazil;
F. c. amazonicus (Hellmayr, 1902) – found in central Brazil;
F. c. ruficeps (von Spix, 1824) – found in east, southeast and south Brazil.
Begin with the source’s own compact description: “Rufous-capped antthrush” is species of bird. The dossier treats that line as a proposition to test through Rufous-capped, antthrush and species, not as a finished interpretation.
Why this record matters
The phrase “species of bird” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q941540. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1779, 1783, 1855 and 1902.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
