The Spot-breasted Thornbird is a furnariid of woodlands, savannas, scrub, and wetlands in northwestern Argentina. Its rufous head and pale-marked breast stand out; it builds an elongated nest of twigs.
The forehead and crown are rufous, the eyebrow and throat whitish, and the back and wings chestnut. The underparts are pale, with a cinnamon-toned breast.
It builds an elongated twig nest supported by branches and lines its chamber with grass, moss, and feathers. The SIB account reports four white eggs.
