About Rhopias gularis (Spix, 1825)
Rhopias gularis, commonly known as the star-throated antwren, measures 8.5 to 9.5 cm (3.3 to 3.7 in) in length and weighs 10 to 12 g (0.35 to 0.42 oz). Adult males have a grayish forehead, and rufous-brown crown, upperparts, and tail, with a hidden white patch between the scapulars. Their wings are mostly rufous-brown with white at the bend, and blackish brown coverts dotted with pale cinnamon. Males have a black throat with white spots, gray breast and belly, and pale rufous-brown flanks and undertail coverts. Females have a buffy forehead, larger white throat spots than males, and no white patch between the scapulars. The star-throated antwren is found in coastal southeastern Brazil, ranging from southeastern Bahia south into northeastern Rio Grande do Sul and inland to western Paraná. It lives in the understorey of evergreen forest. It favors dense vegetation along streams in lowlands and in shady ravines in foothills. It mostly occurs at elevations between 300 and 1,550 m (1,000 and 5,100 ft), though it can also be found as low as sea level.
