About These Birds
Bearded Wood-partridge
A medium-sized New World quail (~405 g) of family Odontophoridae, with a distinct facial streak resembling a beard. Endemic to cloud forest in a restricted area of the Sierra Madre Oriental of eastern Mexico. Forages on the ground for seeds and invertebrates. Vulnerable; critically restricted range in highly fragmented Mexican highland forests, with ongoing habitat loss from agricultural expansion.
Dark-backed Wood-quail
A medium-sized New World quail (~320 g) of family Odontophoridae, with a dark brown back and rufous underparts. Inhabits humid forest on both slopes of the Andes in western Ecuador and Colombia below 1,500 m elevation. Forages on the forest floor for seeds, invertebrates, and fallen fruits. Least Concern; found in Chocó and western Andean forests, relatively tolerant of some disturbance.
