Conservation status according to BirdLife International: Least Concern

Other common names: Calandria de Tres Colas, Calandria de Alas Blancas.

Synonyms: Turdus triurus.


Description: It is a medium-sized passerine bird with a slender and elegant appearance, easily identified by its long tail with large white patches, especially noticeable in flight. The overall plumage is pale gray to brownish-gray, with dark wings showing well-defined white markings. The bill is slender and slightly curved, suited to a varied diet, and the legs are long and dark, providing agility on the ground.

Geographic distribution: It is mainly distributed across central and southern South America, occurring widely in Argentina, Uruguay, Paraguay, southern Bolivia, and parts of southern Brazil. It shows seasonal and local movements related to resource availability and climatic conditions.

Habitat: It inhabits open and semi-open environments, including grasslands, shrub-steppes, scrublands, woodland edges, rural areas, and suburban zones. It favors landscapes with low vegetation and open spaces that facilitate foraging and vigilance.

Feeding: Its diet is omnivorous and opportunistic, consisting primarily of insects, spiders, and other invertebrates, captured on the ground or among vegetation. Fruits, seeds, and berries are also consumed, particularly when animal prey is scarce.

Behavior: It is an active, territorial, and approachable species, usually seen alone or in pairs. It moves swiftly across the ground, frequently stopping to scan its surroundings. The song is melodic and varied, with a notable ability to mimic other bird species, especially during the breeding season.

Nesting: Nesting takes place in shrubs or low trees, where a bulky nest made of twigs and grasses is built. The clutch typically consists of 2 to 4 eggs, mainly incubated by the female, while the male assists in territory defense and chick care.

Conservation status: It is classified as Least Concern, with generally stable populations throughout most of its range, although habitat alteration may cause localized effects.
