Cinereous-breasted Spinetail

The cinereous-breasted spinetail (Synallaxis hypospodia) is a small, skulking bird in the family Furnariidae, found in interior South America, primarily across central and southern Brazil extending into eastern Bolivia and potentially adjacent Paraguay. It inhabits dense, tangled undergrowth in dry scrub forest, cerrado, and woodland edge habitats, remaining close to the ground and typically visible only briefly as it moves through thick vegetation. The species has a slender, graduated tail—characteristic of the spinetail group—and gray-washed underparts that give it its name. The cinereous-breasted spinetail is classified as Least Concern by the IUCN, though monitoring within its range is limited. Its habitat preference for cerrado and dry woodland is significant, as cerrado is one of the world's most threatened biomes, with less than half of the original vegetation remaining due to agricultural conversion, primarily for soy and cattle production. The species is typically detected by its distinctive song rather than direct sighting, as its secretive behavior makes visual observation difficult. Like other Synallaxis spinetails, it builds a large domed stick nest with a side entrance tunnel, often placed in dense bushes. Any database records associating this species with Norway are data artifacts; its range is entirely within interior South America.
