Habitat Comparison
Song & Call Comparison
Bearded Wood-partridge
Emits a loud, resonant hooting call similar to other Dendrortyx wood-partridges. The owl-like hooting carries through cloud forest; calls are poorly differentiated from Long-tailed.
Dark-backed Wood-quail
Resonant, low-pitched 'pow-POW-ow' duet song; second note highest, third trailing off. Usually delivered at dawn. Flushes with explosive wing clatter and sharp alarm chips.
Geographic Range & Migration
Bearded Wood-partridge
Endemic to cloud forest in the Sierra de Juárez, Oaxaca, Mexico, and adjacent Veracruz at 1,500-2,500 m. Rarely observed.
Dark-backed Wood-quail
Resident in the Pacific Andes of Ecuador and northern Peru at 600-1,800 m. Found in humid foothill and montane forest.

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.
