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.
Chestnut Wood-quail
Loud, rhythmic 'po-PO-co' call repeated in series; rich hollow timbre audible 300+ meters. Contact between birds is a soft low grunt; group roost calls are continuous murmuring.
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.
Chestnut Wood-quail
Endemic to the western Andes of Colombia at 1,300-2,400 m. Found in humid montane forest. Vulnerable.

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.
Chestnut Wood-quail
A medium-sized New World quail (~340 g) of family Odontophoridae, with rich chestnut underparts and brownish upperparts. Endemic to the western and central Andes of Colombia at 1,200–2,500 m elevation. Inhabits humid montane cloud forest. Forages on the forest floor for seeds and invertebrates in pairs or small groups. Least Concern; restricted Colombian endemic but not currently threatened.
