Upper mandible slightly notched at the tip, and thicker at the base than the under one: commissure sinuated: culmen slightly arched from the base. Wings short, rounded; the two first quills graduated. Tail moderate, rounded; the feathers rather narrow. Feet strong. The lateral toes nearly equal. Claws slender, slightly curved.  America only.  G. rufescens. Part 5. No. 102.  superciliosa. Ib. No. 101." (Swainson 1837). Alluding to the scrubby habitats favoured by these American sparrows (pace Gruson 1972: “Greek for “blood-loving,” coined from haima, “blood,” and philos, "loving." Why? Swainson, who named the genus, gives no data.”).
Var. Haemophila, Haimophila.
