The Atlantic plain xenops, also known as the white-throated xenops, is a passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Paraguay.
Region
Atlantic Forest of southeastern South America
Typical Environment
Occurs in humid broadleaf forests of southeastern Brazil, eastern Paraguay, and northeastern Argentina (notably Misiones). It occupies interior and edge habitats, including secondary growth, riparian woodland, and forest fragments. Most foraging takes place in the understory to midstory, especially on dead branches, vine tangles, and epiphyte-laden limbs. It tolerates some disturbance but relies on forested cover.
Altitude Range
Sea level to 1500 m
Climate Zone
Subtropical
Ease of Keeping
Beginner friendly: 1/5
A tiny ovenbird that pries insects from dead twigs and bark, behaving a bit like a nuthatch. In the Atlantic Forest it is often called the white-throated xenops, reflecting its pale throat that sets it apart from other xenops. It frequently joins mixed-species flocks and is notably active and acrobatic as it forages.
Temperament
active and inquisitive
Flight Pattern
short rapid wingbeats between perches; brief undulating hops within the canopy
Social Behavior
Usually seen singly or in pairs and commonly joins mixed-species flocks. Nests in cavities or tunnels in rotting wood or earthen banks, lining the chamber with plant fibers. Both sexes participate in nest excavation and care of the young.
Migratory Pattern
Resident
Song Description
Gives thin, high-pitched tseet notes and short, buzzy trills. Calls are sharp and contact-oriented, often delivered while moving through mixed flocks.
Plumage
Warm brown upperparts with rufous wings and tail; whitish throat contrasting with buffy underparts that may show faint dusky streaking on the breast. Fine, compact feathering gives a clean, plain look overall.
Diet
Primarily feeds on small arthropods such as beetles, ants, and their larvae, gleaned from bark, dead twigs, and leaf clusters. It probes and chisels into soft or decayed wood and inspects curled leaves and epiphytes. Occasional small fruits or seeds may be taken opportunistically.
Preferred Environment
Forages in the understory to mid-canopy of humid forests, especially where dead wood and vine tangles are abundant. Frequently works along forest edges and within secondary growth but remains tied to wooded habitats.
