The freckle-breasted thornbird is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Uruguay, and possibly Paraguay.
Region
Southern Cone of South America
Typical Environment
Occurs in northeastern and central Argentina, Uruguay, southern Brazil (notably Rio Grande do Sul and adjacent states), and possibly adjacent Paraguay. Prefers riparian thickets, marsh and lagoon margins, pampas grasslands with scattered shrubs, and second-growth scrub. Frequently uses hedgerows, fence lines, and willows along waterways in agricultural landscapes. Typically found in dense, low to mid-story vegetation where it forages and nests. Often stays close to water or damp soils but can extend into drier shrublands in its range.

Freckle-breasted thornbirds are skilled stick-architects, building large, thorny nests in shrubs or small trees, often near water. Pairs remain together year-round and frequently duet with fast, rattling songs to advertise territory. They adapt well to lightly modified landscapes such as fence lines and canal edges. Their long, rufous tail is often flicked while they forage in dense cover.
Temperament
secretive but active, typically in pairs
Flight Pattern
short rapid wingbeats with low, darting flights
Social Behavior
Primarily seen in territorial pairs or small family groups. Monogamous pairs cooperate in building large, thorny stick nests placed in shrubs or small trees, often over or near water. Both sexes participate in incubation and chick-rearing and aggressively defend the nest.
Migratory Pattern
Resident
Song Description
A rapid, rattling series of harsh notes often given as duets by the pair, accelerating and rising slightly. Calls include dry chatters and scolds from inside dense cover.
Plumage
Warm rufous-brown upperparts with a long, graduated tail; underparts buffy with fine dark freckles and streaks across the breast and throat. Crown and nape slightly darker with subtle streaking; a pale, diffuse supercilium may be evident. Tail feathers appear somewhat spiny-tipped and richly rufous.
Diet
Feeds mainly on insects and other small arthropods such as beetles, caterpillars, and spiders. Gleans from foliage, twigs, and stems and probes tangles of sticks or leaf litter. Occasionally takes small prey from the ground or along muddy margins near water.
Preferred Environment
Forages in dense shrubs, willows, and reed edges along streams, marshes, and irrigation canals. Also uses hedgerows, scrubby pastures, and second-growth thickets where cover is abundant.
