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.
Buffy-crowned Wood-partridge
A medium-sized New World quail (~370 g) of family Odontophoridae, with a buffy-white supercilium and rufous-brown plumage. Inhabits montane cloud forests and humid highland forests from Mexico through Central America to Panama. Forages on the ground for seeds, berries, and invertebrates. Least Concern; commonly heard but seldom seen due to dense forest cover and secretive behavior.
