species of bird
The Sincora antwren (Formicivora grantsaui) is a small, Vulnerable species of passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to a small area of eastern Brazil.
Taxonomy and systematics
The Sincora antwren was first described in 2007 from specimens collected near the small town of Mucugê in the state of Bahia, eastern Brazil. The specific epithet commemorates the German-born naturalist Rolf Grantsau who had collected a specimen in 1965. Coincidentally, another species was also described from the same region in 2007, the Diamantina tapaculo (Scytalopus diamantinensis).
The Sincora antwren is monotypic.

Why this record matters
“Sincorá antwren” is worth following because a concise public description often conceals a longer documentary argument. Here, Sincorá, antwren and species provides the most credible route into that argument.
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 Sep 19, 2026. The linked authority identifier is Q1262358. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007 and 1965.
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.
