Sinkora Karıncakuşu Formicivora grantsaui

Range-restricted antwren of the Serra do Sincorá. Males are brown above and black below, with a white eye-line that stretches down to the underparts. Females have black underparts streaked with white. Found in low scrub and grasslands in rocky areas. The song is a continuous repetition of high, slow “tjew” notes. The similar but more widespread Rusty-backed Antwren has a rufous back and a different song.
