Typical tinamou of puna and high Andean environments, measuring 32 to 36 cm. It has a uniform slate-gray chest that contrasts with a lighter, buff-colored belly. The head and neck show abundant black spots on a whitish background, forming a very striking pattern. The back and wings display an intricate design of wavy lines, bars, and black, ochre, and beige spots that provide excellent camouflage among grasses and rocks. It has a small dark crest that is usually raised when alert and a relatively long, thin bill slightly curved downward. The legs are yellowish to grayish. Sexes are similar. Juveniles show browner tones and less marked facial spotting.
In part of its range it may coexist with other high Andean tinamous such as the Guaipo (Rhynchotus maculicollis) and the Silvery Tinamou (Nothoprocta pentlandii), although it has a uniform gray chest and a distinct vocalization. It can also be confused with the Lesser Nothura (Nothoprocta cinerascens), although this latter species mainly inhabits lower Chaco environments.
Geographic distribution: It inhabits the central Andes from Peru to northwestern Argentina, passing through Bolivia and northern Chile. In Argentina it is distributed across Jujuy, Salta, Tucumán, Catamarca, and La Rioja. It is mainly found between 2,500 and 4,500 meters above sea level, although locally it may descend to lower elevations. It is considered a resident species within its range, although it may perform local altitudinal movements.
Habitat: It is one of the most common tinamous of the Puna and upper Yungas grasslands. It inhabits puna steppes, high-altitude grasslands, rocky slopes, ravines, high Andean shrublands, and mountain valleys. It is usually found in areas with bunch grasses or tola shrubs, rocky outcrops, and areas near watercourses or wetlands. It can also be seen near mountain crops.
Feeding: Omnivorous. It feeds mainly by walking on the ground while pecking seeds, shoots, tender leaves, fruits, roots, and other plant material. It supplements its diet with insects and various arthropods. Occasionally it consumes crops and other resources available in modified environments.
Behavior: Generally solitary or in pairs. It spends most of its time on the ground moving slowly among grasses and shrubs, although it can occasionally be seen walking in open areas. When detecting a threat, it tends to hide in vegetation or run before taking flight. When it finally flies, it does so explosively and noisily, alternating rapid wing beats with short glides to move away and hide again. It often remains on rocks or elevated terrain, where it sunbathes, preens, or watches its surroundings (personal observations). During the breeding season it vocalizes frequently from slopes and open grasslands. It emits sharp, plaintive whistles, often repeated in series over long periods. It also produces simple contact or location calls that may be repeated at regular intervals. Vocalizations are more frequent during early morning and at dusk.
Nesting: The nest consists of a depression lined with dry vegetation, feathers, and other available materials, built on the ground, usually sheltered by grass clumps or shrubs. The clutch usually contains 4 to 9 very shiny violet-chocolate eggs with a glossy, ceramic-like appearance. As in other tinamous, the male is mainly responsible for incubation and later leads the chicks after hatching.
Conservation status: Considered Least Concern at national and international levels due to its wide distribution and because it remains relatively common throughout its range, even in moderately modified environments. However, it may be locally affected by hunting pressure, especially near settlements and rural areas, and grassland and high Andean wetland degradation due to overgrazing and other activities may also affect some populations.
