Plain-colored Seedeater is fairly common throughout its range. They occur along the high Andes, where they inhabit high open lands such as paramo and agricultural areas. They forage on or near the ground. Though only in pairs while nesting, they form flocks when not breeding and occasionally join other high-elevation finch species. They can be separated from the other species by their pinkish-orange bill and overall uniform color. Males are pale gray, whereas females are uniformly streaked brown. Note also the lack of white in the tail and wing, unlike Band-tailed Seedeater. Their song is a series of buzzes, rich whistles, and chatters.
