Recently rediscovered tanager. Males are black and white with a whitish-gray bill and small white wing patch. Females are uniformly olive-brown with a darker bill. Found in seasonally flooded forests along rivers and in gallery forest, but always near water. Forages at lower levels but also perches in the tops of trees. Feeds on seeds but also has been reported flycatching. The song begins with a series of low notes and finishes with a trill: “tche, tche, tche, tche, tche, tcherrrrrrrrrrrr, tcherrrrrrrrr, tiiiiiiiiiiiiiiiiiiiiiiiiii.”
