Description
The chestnut wood quail is long. Males weigh and females . Both sexes have grayish white feathers around the eye, with the female's more extensive. Adult males have a chestnut head and brown back, rump, and wings. The rump has fine black vermiculation
Vermiculation is a surface pattern of dense but irregular lines, so called from the Latin ''vermiculus'' meaning "little worm" because the shapes resemble worms, worm-casts, or worm tracks in mud or wet sand. The word may be used in a number of ...
. The throat and undersides are rufous. The adult female's crown is dusky brown and its breast and belly are dark gray. The juvenile is similar to the adult female.[

Distribution and habitat
The chestnut wood quail is found mostly in the western and central Andes of Colombia and locally in the eastern Andes. In elevation it ranges from . It inhabits the interior and edges of subtropical montane forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial ...
, both primary and secondary. It is primarily terrestrial but has been seen roosting as high as above ground.[

Behavior
Feeding
The chestnut wood quail forages by scratching in leaf litter for roots, seeds, fallen berries, and probably also insects.[
]
Breeding
The chesnut wood quail appears to have two nesting seasons that correspond to the wettest part of the year, March to May and October to December. Nests are domed globes on the ground made of leaves and twigs with a short tunnel entrance. The clutch size is four or five and the female alone incubates the eggs. Family groups stay together for many months after hatching.[
]
Vocalization
The chestnut wood quail's advertising call is "a rollicking, rapidly repeated duet, 'orrit-kilyit...'". It also has an alarm call, "a low 'peetit, peetit...'".[
]
Status
The IUCN has assessed the chestnut wood quail as being of Least Concern. Until 2020 it had been rated Near Threatened. Though its population size is not known and is thought to be declining, those criteria are not critical enough to warrant a more perilous rating.[
