Medium-sized seedsnipe measuring 19–24 cm, with a compact body but more slender than the large seedsnipes (Attagis), with a small head, short neck, and short wedge-shaped tail. Cryptic plumage in cinnamon, beige, and brown tones with fine vermiculations. In flight, wings long and pointed; above with cryptic pattern, below with strong contrast between dark coverts and extensive white. Bill short, conical, yellowish with black tip, with a sheath at the base protecting the nostrils in windy, dry, and dusty environments. Legs yellow to orange. Shows sexual dimorphism. Male: head, neck, and chest uniform gray, bordered by a fine dark collar and white throat; belly whitish. Female: duller, with head and chest ochraceous and heavily streaked. Juvenile similar to female. Very similar to the Least Seedsnipe (T. rumicivorus), with which it coexists: the collared male differs by lacking the vertical black line on the chest that is present in the male of the smaller species. Females are very difficult to identify in the field.
Distribution: Broad Andean distribution from northern Peru to Tierra del Fuego. In Argentina it occurs along the Andes and Patagonia. Two main subspecies are present in the country: North (ingae): Andes from northwestern Argentina to Catamarca; in Tucumán present in the Cumbres Calchaquíes, above 3,800 m a.s.l., where it becomes common (pers. obs.). South (orbignyianus): from La Rioja south to Tierra del Fuego. Performs altitudinal movements, descending in winter and reaching lowlands in Patagonia.
Habitat: Inhabits open high Andean and Patagonian environments: steppes, rocky slopes, scattered scrub, wet meadows, bofedales, and peatlands. In the north it occurs mainly between 3,000 and 5,000 m a.s.l., while in the south it inhabits from sea level to mid elevations.
Behavior: Terrestrial species, generally in pairs or small groups; outside the breeding season may form flocks. Discreet and highly cryptic, often remains motionless or crouches to avoid detection. Walks slowly, alternating with quick movements while feeding. Males act as sentinels during the breeding season. Flight low, fast, and direct. Produces soft, monotonous, repetitive vocalizations, sometimes in flight. Also emits shorter, sharper calls in alarm situations. Often vocalizes at night (pers. obs.).
Diet: Feeds mainly on plant material: shoots, leaves, and seeds. Forages on the ground, alone or in small groups, taking food continuously.
Breeding: Nests on the ground, usually in a depression protected by vegetation. Clutch of 3 to 4 eggs, pale with spots. Chicks are precocial and cryptic.
Conservation status: In Argentina it is categorized as Not Threatened (NT) and globally as Least Concern (LC). Locally common in suitable sites, but potentially affected by habitat modification, especially mining and overgrazing.
