Song & Call Comparison
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.
Spot-winged Wood-quail
Deep, booming 'whup-WHUP-whup' duet calls resonating through Atlantic forest undergrowth. Contact calls are low, guttural clucks; alarm produces explosive 'puk' notes.
Geographic Range & Migration
Bearded Wood-partridge
Endemic to cloud forest in the Sierra de Juárez, Oaxaca, Mexico, and adjacent Veracruz at 1,500-2,500 m. Rarely observed.
Spot-winged Wood-quail

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.
Spot-winged Wood-quail
A medium-sized New World quail (~425 g) of family Odontophoridae, with spotted brown plumage and an orange eye ring. Inhabits Atlantic Forest, cerrado woodland, and interior humid forests of eastern South America in Brazil, Paraguay, and Argentina. Forages on the forest floor for seeds and invertebrates. Least Concern; dependent on forest cover but broadly distributed in southeastern Brazil.
