Habitat Comparison
Song & Call Comparison
Ocellated Quail
Mournful, slightly wavering whistle similar to Montezuma Quail but with 5–6 syllables; descending in pitch. Male calls from shaded scrub. Alarm is a sharp nasal clucking series.
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.
Geographic Range & Migration
Ocellated Quail
Resident in the highlands of Central America from Guatemala to Nicaragua at 600-2,000 m. Found in pine-oak and humid montane forest.
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
Ocellated Quail
A small New World quail (~200 g) of family Odontophoridae, with ocellated (eye-spot) patterning on the upperparts. Inhabits pine-oak forests and adjacent grasslands in highland Guatemala, Honduras, El Salvador, and Nicaragua. Forages for seeds and invertebrates. Vulnerable; restricted range, rare throughout its distribution, and threatened by habitat degradation from logging and overgrazing.
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.
