Large brown seedeater with two pale wingbars and a big, bulging bill. Varies geographically in the amount of streaking on the crown and underparts and the presence or absence of a pale forehead patch. Found in montane habitats including forest, forest edge, bamboo, and scrub. Generally inconspicuous, but will perch up to sing. The call is a high, thin “tsreep-tseet,” and the song is a complex and exuberant jumble of whistled and rattling notes. Somewhat similar to Streaky Seedeater, but larger and heavier-billed, with a much darker and less patterned head.
