Distribution in the Americas

Spix's Spinetail is resident in the eastern South America, in southeastern Brazil (north to Minas Gerais and Espirito Santo), eastern Paraguay, northeastern Argentina (south to Buenos Aires), and all of Uruguay (Hellmayr 1925, Pinto 1937, Ridgley and Tudor 1994, Hayes 1995, Olmos 2009).

The elevational range of Spix's Spinetail is from the lowlands up to at least 2200 m (Parker et al. 1996).

Distribution outside the Americas

Spix's Spinetail is endemic to the Americas.


Generally Spix's Spinetail occurs in dense second growth scrub and similar habitats. Descriptions of the habitat include Atlantic lowland forest, campos, fields, pastures, (Aleixo and Galetti 1997); capoeira (brushy second growth), thickets, grass clumps, and heavy undergrowth in marshy areas (Belton 1984); forest fragments, gallery forest, riparian forest, and campo rupstre (Melo-Junior et al. 2001); restringa, antropic areas, roads and pastures (Naka et al 2002); and "in bushes and low capoeira mixed with sapé thatching grass at the edge of forest" (Sick 1993).
