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.
Black-fronted Wood-quail
Melodic 'cu-cu-ROOOO' duet echoing in Andean cloud forest; pairs synchronize notes precisely. Alarm is a sharp 'kuk' repeated in rapid bursts when predator detected.
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.
Black-fronted Wood-quail
Resident in the mountains of northern Colombia and northwestern Venezuela at 500-2,200 m. Found in humid cloud and foothill 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.
Black-fronted Wood-quail
A medium-sized New World quail (~290 g) of family Odontophoridae, with a distinctive black forehead. Inhabits montane and foothill forests in the Andes and Sierra Nevada de Santa Marta of Colombia and Venezuela at 500–2,000 m elevation. Forages on the forest floor in pairs for seeds and invertebrates. Least Concern; found in Andean forests with populations considered relatively stable.
