The Five-striped Sparrow, Aimophila quinquestriata (Sclater and Salvin), consists of two subspecies locally distributed in two parts of western Mexico. Until recently the paler northern subspecies, A. q. septentrionalis van Rossem, was largely restricted (in summer) to Sonora, while the darker A. q. quinquestriata was known only from northern Jalisco and vicinity. Like all little-known tropical or semi-tropical birds, the Five-striped Sparrow has generally been assumed to be sedentary (Wolf 1977, A.O.U. 1983).
