Habitat Comparison
Song & Call Comparison
Montezuma Quail
Eerie, descending wavering whistle 'wheeeoo' given by male from grass; ghostly and ventriloquial. Alarm is a low nasal 'wee-wee'; flushed birds produce loud burst of wing beats.
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.

About These Birds
Montezuma Quail
A small rotund New World quail (~185 g) of family Odontophoridae, males with a harlequin-patterned black and white face. Inhabits pine-oak and grassland habitats in montane areas from Arizona and Texas to Honduras. Forages by digging bulbs and tubers with strong curved claws. Least Concern; cryptic and rarely seen; populations declining with overgrazing of native bunchgrass.
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.
