Conservation status according to BirdLife International: Least Concern

Synonyms: Stilpnia preciosa, C[allispiza] preciosa, Tangara preciosa.


Description: It is a small to medium-sized tanager notable for its striking and contrasting plumage, featuring a particularly eye-catching color combination within its group. The male shows bright turquoise, greenish, and bluish tones, with darker areas enhancing the brilliance of its feathers under good lighting. The female, by contrast, has a more subdued appearance, dominated by olive greens and muted tones, allowing it to blend into the vegetation. The bill is short and relatively strong, suitable for a varied diet.

Geographic distribution: It occurs in southern Brazil, Paraguay, Uruguay, and northern Argentina, mainly in subtropical and temperate regions of eastern South America. Its presence may vary seasonally, with more frequent records in certain times of the year, particularly toward the southern edge of its range.

Habitat: This species inhabits gallery forests, humid woodlands, secondary growth, and forest edges, showing some tolerance to modified environments as long as tree cover is maintained. It is often associated with areas near watercourses and can also be found in parks and wooded gardens, where food and shelter are available.

Diet: Its diet is primarily frugivorous, feeding on small fruits and berries, making it an important seed disperser. It also consumes insects and other invertebrates, especially during the breeding season when protein needs increase.

Behavior: It is usually seen in pairs or small groups, often joining mixed-species flocks. It is active and moves agilely through the mid to upper levels of vegetation while foraging. Although it can be somewhat inconspicuous, its bright coloration becomes evident when exposed to light. It emits soft, high-pitched calls used for communication.

Nesting: It builds a cup-shaped nest made of plant fibers, placed on sheltered branches within vegetation. The female is mainly responsible for incubation, while the male may assist with feeding. Clutch size is usually small, and parental care continues until the young become independent.
Conservation status: It is not considered globally threatened, but depends on the conservation of forested and wooded habitats. Habitat loss and fragmentation may affect local populations.

Movements: In part of its range, especially in the southern regions, it shows migratory or seasonal movements, with records suggesting movements toward more southern areas during winter, indicating some flexibility in its spatial use throughout the year.
