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.
Venezuelan Wood-quail
A medium-sized New World quail (~340 g) of family Odontophoridae, with brownish-rufous plumage. Endemic to the coastal mountain range of northern Venezuela. Inhabits humid montane and cloud forests at moderate elevations. Forages on the forest floor for seeds and invertebrates. Near Threatened due to restricted range and ongoing deforestation in the Venezuelan coastal cordillera.
