About These Birds
Northern Bobwhite
A small New World quail (~195 g) of family Odontophoridae, males with a white supercilium and throat on brown-patterned plumage. Found in open woodlands, grasslands, and agricultural edges across eastern North America and Mexico. Forages in coveys for seeds and insects. Near Threatened; once abundant but suffering severe range-wide declines from agricultural intensification, habitat loss, and pesticide use.
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.
