Records from Esteros del Iberá

Conservation status according to BirdLife International: Least Concern

Other common names: Alonsito, Caserito.

Synonyms: Merops rufus.

Subspecies:


Description: It is a medium-sized passerine bird, easily recognized by its predominantly rufous-brown plumage, slightly darker wings, and paler throat. The body is sturdy, with a short tail and a strong, straight bill well adapted for ground foraging. Its compact appearance and upright posture are especially noticeable when walking across open areas.

Geographic distribution: It is widely distributed across central and southern South America, including Argentina, Uruguay, Paraguay, Bolivia, southern Brazil, and parts of eastern Chile. The species is very common throughout much of its range, particularly in lowland temperate regions, where it remains present year-round.

Habitat: It inhabits a wide variety of open and semi-open environments, such as grasslands, savannas, agricultural fields, rural areas, and urban settings. It shows remarkable adaptability to human-altered landscapes and is frequently observed in gardens, parks, and near buildings.

Feeding: Its diet is mainly insectivorous, consisting of insects, larvae, spiders, and other small invertebrates collected while walking on the ground. Occasionally, it may consume small amounts of plant material. Foraging is active, often involving probing and turning over soil with the bill.

Behavior: It is a territorial and generally monogamous bird, usually seen alone or in pairs. The species is notably tolerant of human presence and is well known for its loud, repetitive song, which plays an important role in territorial defense and pair communication.

Nesting: It builds one of the most distinctive nests among South American birds: a mud structure shaped like an oven, with a lateral entrance leading to an inner chamber. Both members of the pair participate in nest construction, which is typically placed on posts, trees, buildings, or artificial structures. The usual clutch consists of 3 to 4 eggs, incubated by both adults.

Conservation status: It is classified as Least Concern, owing to its broad distribution, large population size, and high adaptability to human-modified environments.
