Description: It is a medium-sized bird with a robust body and large head, characterized by a strong, conical bill well suited for a varied diet. The overall plumage shows grayish to olive tones, darker on the upperparts and paler below. A distinctive feature is the well-defined pale eyebrow, ranging from whitish to buff, contrasting with a darker eye line. The throat is usually paler, while the wings and tail are a deeper gray. Sexual dimorphism is minimal, and juveniles resemble adults but appear duller and less contrasted.
Geographic distribution: This species is widely distributed across South America, occurring in Brazil, Paraguay, Bolivia, Uruguay, and northeastern to central-eastern Argentina. In Argentina, it is mainly found in the northeastern and central regions, including the Litoral, Chaco, Mesopotamia, and surrounding areas. Its distribution closely follows the presence of suitable vegetated habitats.
Habitat: It inhabits a variety of wooded and semi-open environments, such as gallery forests, forest edges, Chaco woodlands, shrublands, and tree-dotted savannas. It also adapts to rural landscapes, large gardens, and peri-urban areas with sufficient vegetation cover. The species typically moves at low to mid-levels within dense foliage, using vegetation as shelter.
Diet: The diet is omnivorous, with a strong emphasis on plant material. It feeds on fruits, seeds, buds, flowers, and cultivated grains, using its powerful bill to crush hard items. Insects and other small invertebrates are also consumed, particularly during the breeding season. Foraging is deliberate and methodical, often within thick vegetation.
Behavior: Generally quiet and unobtrusive, it is most often seen alone or in pairs, occasionally forming small family groups. It moves calmly through the vegetation but becomes more active while feeding. The species is well known for its loud, melodic song, composed of clear, whistled phrases used in territorial defense and social communication.
Nesting: Breeding mainly occurs during spring and summer. The nest is an open cup made of twigs, plant fibers, and soft materials, placed in shrubs or small trees. Typical clutches consist of 2 to 3 eggs, pale with darker blotches. Both parents share nest defense and chick provisioning until fledging.
Conservation status: Globally listed as Least Concern, due to its wide range and stable populations. However, habitat loss and fragmentation may cause localized declines in some areas.
