The rufous-fronted wood quail (Odontophorus erythrops) is a species of bird in the family Odontophoridae, the New World quail. It is found in Colombia and Ecuador.
Taxonomy and systematics.
The rufous-fronted wood quail has at various times been proposed or considered as conspecific with chestnut wood quail ("Odonophorus hyperythrus"), dark-backed wood quail ("O. melanonotus"), and rufous-breasted wood quail ("O. speciosus"). "O. melanonotus" has also been considered a subspecies of "O. erythrops", and at least two other variations have been proposed as subspecies. As of 2021, rufous-fronted wood quail and chestnut wood quail are treated as a superspecies. 
The rufous-fronted wood quail has two subspecies, the nominate "O. e. erythrops" and "O. e. parambae". To complicate matters, the latter has also been considered to be a separate species.
Description.
The rufous-fronted wood quail is long. Males weigh an estimated and females an estimated . The nominate male has a rufous crown, crest, and face, with a ring of bare purple skin around the eye. The back and rump can be black or olive, with black spots. The breast and belly are dark rufous. The female's face is a darker and duller chestnut and the eye ring is blue-black. The juvenile is similar to the female but differs mostly by having black spots and bars on the belly. "O. e. parambae" has darker upperparts than the nominate and a white throat.
Distribution and habitat.
The nominate subspecies of rufous-fronted wood quail is found in southwestern Ecuador. "O. e. parambae" is found more widely, on the Pacific slope of western Ecuador and western Colombia and in Colombia's Magdalena Valley. They inhabit primary and secondary humid tropical forest, in Ecuador up to but usually only as high as in Colombia.
