The '''bearded wood partridge''' ('''''Dendrortyx barbatus''''') is a [[bird]] species in the family [[Odontophoridae]], the New World quail. It inhabits the [[Sierra Madre Oriental]] of Mexico.<ref>{{Cite journal |last1=Mota-Vargas |first1=Claudio |last2=Galindo-Gonzalez |first2=Jorge |last3=Rojas-Soto |first3=Octavio |year=2017 |title=Crumble analysis of the historic sympatric distribution between ''Dendrortyx macroura'' and ''D-barbatus'' (Aves: Galliformes)|journal=PLOS ONE |volume=12 |issue=9 |pages=e0183996 |doi=10.1371/journal.pone.0183996 |pmid=28863140 |pmc=5580918 |bibcode=2017PLoSO..1283996M |doi-access=free}}</ref>
==Taxonomy and systematics==
The bearded wood partridge shares the genus ''Dendrortyx'' with two other species, all of which appear to be quite distinct from each other.<ref name=BEWP-BOW>Eitniear, J. C. (2020).

==Description==
The bearded wood partridge is {{convert|33|to|35.5|cm|in|abbr=on}} long and weighs between {{convert|405|and|459|g|oz|abbr=on}}. Adults have bluish gray cheeks, neck, and upper chest. There is a red patch around the eye. The crown is buff and has a small crest. The nape and chest are cinnamon, with red striations on the nape and sides of the chest. The back is a mix of buff, browns, and grays. Immatures are similar to the adults but their chest is duller and the flanks have brown bars.<ref name=BEWP-BOW/>
==Distribution and habitat==
The bearded wood partridge has a discontinuous range in the central part of Mexico's Sierra Madre Oriental. The Santo Domingo River in northern Oaxaca and western slope of the Sierra Madre Oriental act as biogeographic barriers.<ref>{{Cite journal |doi = 10.1017/S0959270912000329|title = Geographic and ecological analysis of the Bearded Wood Partridge ''Dendrortyx barbatus'': Some insights on its conservation status|journal = Bird Conservation International|volume = 23|issue = 3|pages = 371–385|year = 2013|last1 = Mota-Vargas|first1 = Claudio|last2 = Rojas-Soto|first2 = Octavio R.|last3 = Lara|first3 = Carlos|last4 = Castillo-Guevara|first4 = Citlalli|last5 = Ballesteros-Barrera|first5 = Claudia|doi-access = free}}</ref><ref>{{Cite journal |jstor = 3672468|title = New Records of Bearded Wood-Partridge, ''Dendrortyx barbatus'', (Aves: Phasianidae) in Mexico|journal = The Southwestern Naturalist|volume = 45|issue = 2|pages = 238–241|last1 = Eitniear|first1 = Jack C.|last2 = Sergio|first2 = Aquilar R.|last3 = Gonzalez|first3 = Victor|last4 = Roberto|first4 = Pedraza R.|last5 = Baccus|first5 = John T.|year = 2000|doi = 10.2307/3672468}}</ref> It inhabits the interiors and edges of humid evergreen [[montane forest]] and pine-oak forest, both primary and secondary. It is also found in gardens and sometimes in farmland. It is often restricted to narrow [[riparian]] zones.<ref name=BEWP-BOW/>
==Behavior==
===Feeding===
The bearded wood partridge forages on the ground. Its diet includes seeds, fruits, buds, tubers, and insects.<ref name=BEWP-BOW/>
===Breeding===
Little is known about the bearded wood partridge's breeding [[phenology]]. It is reported to breed between April and June. The male makes a dome-shaped nest with a tunnel entrance. The clutch size is usually five.<ref name=BEWP-BOW/>
===Vocalization===
{{birdsong|url=https://www.xeno-canto.org/species/Dendrortyx-barbatus |species=bearded wood partridge}}
The bearded wood-partridge's song is "a series of loud, rollicking whistles, repeated rapidly and often given in duet". The sexes' songs are similar but the female's is quieter. The song is mostly given at dawn and dusk. Groups sing to maintain contact.<ref name=BEWP-BOW/>
==Status==
The [[IUCN]] has assessed the bearded wood partridge as Vulnerable since 2000 after initially rating it Critically Endangered. "[S]urveys have found this species to be more widespread and numerous than previously thought, however it still has a highly fragmented range and small population undergoing a continuous decline."<ref name=IUCN/>
