Habitat Comparison
Song & Call Comparison
Crested Bobwhite
Whistled ascending 'whiit-wheee' repeated steadily; crest raised during calling bouts. Contact between covey members is a series of low, liquid clucking notes with nasal quality.
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

Resident from Panama south through Colombia and Venezuela to the Guianas. Found in open grassland, savanna, and brushy areas.
Bearded Wood-partridge

About These Birds
Crested Bobwhite
A small New World quail (~130 g) of family Odontophoridae, males with a shaggy brown-white crest. Inhabits open savanna, grassland, scrubland, and agricultural areas in Central America and northern South America. Forages in coveys for seeds and invertebrates on the ground. Least Concern; one of the most widespread bobwhite species, tolerant of human-modified landscapes.
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.
