Sincorá Antwren Formicivora grantsaui NOT YET EVALUATED

Sincora Antwren
Sincorá Antwren Formicivora grantsaui is found only in the campo rupestre vegetation of the Serra do Sincorá between 850 m and 1,100 m in the Chapada Diamantina region. First observed in 1997, it is closely related to Rusty-backed Antwren Formicivora rufa, with which it sometimes occurs sympatrically. It differs slightly in some plumage characters but more importantly it has quite distinctive vocalisations and each species utilises different habitats. Formicivora grantsaui occurs on rocky outcrops in the campo rupestre and F. rufa in the adjacent savannas.
