Source-derived summary

The horned curassow (Pauxi unicornis), or southern helmeted curassow, is a species of bird in the family Cracidae found in humid tropical and subtropical forests. It was first described by James Bond and Rodolphe Meyer de Schauensee in 1939 from a specimen collected in Bolivia, and further birds that were described from Peru in 1971 were thought to be a new subspecies. However, the taxonomic position (as subspecies or independent species) of the birds found in Peru in 1971 is unclear. The horned curassow as originally described is endemic to Bolivia. It is a large, predominantly black bird with a distinctive casque on its forehead. It is an uncommon bird with a limited range and is suffering from habitat loss, and the International Union for Conservation of Nature has rated its conservation status as being "critically endangered".

Taxonomy and systematics

In 1937 while in Bolivia Mr M. A. Carriker found two birds, a male and female, which were in the cracid family. The specimens were subsequently described as a new species by James Bond and Rodolphe Meyer de Schauensee in 1939 and given the scientific name Pauxi unicornis placing it in a genus Pauxi alongside the species P. pauxi. In 1969 another two birds, again a male and female were discovered which resembled those found by Mr. Carriker in 1937.

Editorial summary

This brief starts where responsible research should: with the source description of “Horned curassow” as species of bird. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1939, 1971, 1937, 1969—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Horned, curassow and species can be independently traced.
Editorial analysis

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.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q1078565. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939, 1971, 1937 and 1969.

Critical limits

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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
