Records from Concepción del Yaguareté Corá

Conservation status according to BirdLife International: Least Concern

Description: A medium-sized and slender mockingbird with an upright posture and a clean, elongated profile. Its plumage is mostly grayish to brownish, with subtle streaking on the breast and flanks and paler underparts. The wings show a contrasting pattern of dark and light patches, especially noticeable in flight. It has a slightly curved, fine bill suitable for probing insects and fruit. The yellowish eyes give it a sharp, alert expression. Juveniles display a duller and less contrasted appearance.

Geographical distribution: It occurs widely across South America, from central and eastern Brazil through Paraguay, Bolivia, Uruguay, and much of Argentina, occupying open and semi-open landscapes. It thrives in dry regions, savannas, pampas and even suburban environments.

Habitat: Inhabits open grasslands, scrublands, forest edges, rural environments and urban areas, where it adapts readily. It is frequently observed in gardens, parks and areas with scattered shrubs, often using exposed branches, posts or human-made structures as vantage points.

Diet: Its diet is omnivorous and opportunistic, including insects, small invertebrates, fleshy fruits, seeds and occasionally human-related food items. It forages mainly on the ground, walking with confident steps and pausing to inspect leaf litter or cavities for prey.

Behavior: A highly territorial species, especially during the breeding season. Its song is strong, varied and persistent, often including imitations of other birds. It tends to be bold and active, regularly perching on elevated lookouts. In human-modified areas it may form small family groups and defend resources vigorously.

Breeding: Builds an open and bulky nest of twigs and plant fibers in shrubs, medium-height trees or artificial structures. The clutch typically contains 2 to 4 eggs. The female performs most of the incubation, while both adults defend the territory and feed the chicks until independence.

Conservation status: Classified as Least Concern (LC) globally, supported by its broad range, adaptability and stable populations. It thrives in altered landscapes and often expands into human-modified areas.
