The austral rail is a Vulnerable species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina and Chile.
Region
Patagonia and southern Andes
Typical Environment
Occurs patchily in southern Argentina and Chile, especially in dense freshwater marshes and wet meadows. It favors stands of rushes and sedges with shallow, slow-moving or still water and thick ground cover. Birds skulk along muddy margins under vegetation, rarely venturing into open water. It may also use overgrown ditches and occasionally brackish marshes where cover is abundant. Habitat quality is closely tied to stable water levels and intact emergent vegetation.
Altitude Range
Sea level to 1200 m

Ease of Keeping
Beginner friendly: 1/5
A shy, marsh-dwelling rail of southern South America, the austral rail is most often detected by its loud, grating calls rather than seen. It depends on dense rush- and sedge-filled wetlands, making it vulnerable to drainage, burning, and overgrazing. Conservation actions focus on protecting Patagonian marshes and controlling invasive predators. Its name “antarcticus” reflects its far-southern range, not Antarctica itself.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats; reluctant flier, typically making low, brief flights
Social Behavior
Usually solitary or in pairs, becoming territorial in the breeding season. Nests are placed in dense rush clumps over or near shallow water, built from grasses and sedges. Pairs likely share incubation and care for precocial black chicks that follow adults soon after hatching.
Migratory Pattern
Resident
Song Description
Vocalizations include loud, grating series of kek-kek notes, squeals, and clattering calls. Most vocal at dawn and dusk, and pairs may engage in antiphonal duets that carry across marshes.
