A gray-brown seedeater with a complex brown-and-white facial pattern and a yellow rump that is conspicuous in flight. Found in savanna, woodland, and cultivated areas, usually in small flocks. Similar to Yellow-rumped Serin, but has a stronger facial pattern and usually more streaking below. Separated from White-rumped Seedeater by the yellow rump and the more strongly patterned face. Also similar to Yellow-throated and Salvadori’s Serins, but separated by the white rather than yellow throat. The song is a constant stream of musical whistles and trills.
