Hooded visorbearer
species of bird
The hooded visorbearer (Augastes lumachella) is a small species of hummingbird in the family Trochilidae. Endemic to the east Brazilian state of Bahia, it is found only at higher altitudes in the Chapada Diamantina region. The species is sexually dimorphic.
It resides in the campo rupestre, an arid, high-elevation area characterized by rocky outcrops, poor soils, open habitats, and harsh climatic conditions. There, it feeds primarily on nectar, though it also takes insects. Its breeding ecology remains largely undescribed, though it is known to build its nest from cactus spines. The International Union for Conservation of Nature rates it as a near-threatened species, primarily because of the relatively small size of its range. It is threatened by habitat loss, brought about primarily by unregulated mining and the conversion of the campo to pastureland and human habitation. Climate change is projected to cause a major contraction of its range – perhaps by as much as 90%.
Taxonomy and systematics
Rene Primevere Lesson first described the hooded visorbearer for science in 1838, using a specimen collected in Bahia, Brazil.
Begin with the source’s own compact description: “Hooded visorbearer” is species of bird. The dossier treats that line as a proposition to test through Hooded, visorbearer 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 Mar 27, 2026. The linked authority identifier is Q1267453. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1838.
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.
