Short-tailed antthrush
species of bird
The short-tailed antthrush (Chamaeza campanisona) is a species of bird in the family Formicariidae. It is found in every mainland South American country except Chile, French Guiana, and Uruguay.
Taxonomy and systematics
The short-tailed antthrush was first formally described by Vieillot in 1818 as Turdus brevicaudus. However, because that binomial had previously applied to another species, by the principle of priority Lichtenstein's 1823 description as Myiothera campanisona is recognized as the original. The species was later moved to its current genus Chamaeza. Its specific epithet comes from the Latin "campana" (bell) and "sonus" (sound) and refers to the species' bell-like song.
The International Ornithological Congress (IOC) assigns the short-tailed antthrush these 11 subspecies:
A 2003 publication assigns a twelfth subspecies, C. c. tshororo, though the authors note that it is "doubtfully distinct from [the] nominate" C. c. campanisona. The authors also suggest that the short-tailed antthrush as currently known may include as many as four species.
Begin with the source’s own compact description: “Short-tailed antthrush” is species of bird. The dossier treats that line as a proposition to test through Short-tailed, 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.
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 Oct 5, 2025. The linked authority identifier is Q688012. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1818, 1823 and 2003.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
