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.
Stone Partridge
Emits a clear, whistled peet-peet call and soft clucking series. The repeated, clear whistle is far-carrying and melodious for a partridge; heard on West African rocky outcrops.
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.

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.
Stone Partridge
A small partridge (~190 g) of family Odontophoridae, with brown-barred plumage and a short rounded tail often cocked upright. Inhabits rocky hillsides, inselbergs, and stony savanna in sub-Saharan West and Central Africa. Forages for seeds and insects on the ground. Least Concern; an unusual African member of the New World quail family with a predominantly terrestrial lifestyle.
