Sincora Antwren Formicivora grantsaui


Only recently described, from the interior of Bahia, in northeast Brazil, the Sincora Antwren is morphologically similar to the far more widespread Rusty-backed Antwren (Formicivora rufa), but is very different in respect of its vocalizations, including both the song and calls. The Sincora Antwren is restricted to elevations between 800 and 1100 m of the Serra do Sincorá in the Chapada Diamantina, where it is found in campos rupestres (rocky montane scrub), and it differs from Rusty-backed Antwren in having darker and less rufous upperparts, less yellow on the flanks, and the underwing coverts are grey and white, rather than pure white. The species’ scientific name commemorates the German-born naturalist Rolf Grantsau who collected a specimen in 1965 that was recently identified as Sincora Antwren.
