A small New World quail (~130 g) of family Odontophoridae, with a distinctive black throat in males. Inhabits open pine savannas, grasslands, and agricultural edges from southern Mexico through the Yucatán Peninsula to Nicaragua. Forages on the ground for seeds and invertebrates in small coveys. Least Concern; adapted to fire-maintained savanna habitats of the Caribbean lowlands.
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.
