Chotoy Spinetail Schoeniophylax phryganophilus Scientific name definitions

The Chotoy Spinetail is a small, pale, and secretive furnariid of semi open, dry areas with scattered trees and shrubs, that is found from Bolivia to Uruguay, and central-eastern Brazil. The most remarkable trait in its plumage is the striking black-and-yellow throat, unique among furnariids, along with a long and pointed tail and heavily streaked upperparts. The bird's vocalization is one of the most characteristic sounds of the Chaco and Espinal ecoregions—a guttural, low-pitched series of “cho” notes, reminiscent of a larger bird. It builds a large, globular nest with a long lateral entrance, constructed from thorny sticks. The species is commonly observed alone or in pairs, foraging for arthropods in trees or on the ground. Currently classified as Least Concern, its populations appear stable despite anthropogenic disturbances. In fact, range expansions have been recorded due to deforestation in Bolivia (1 Herzog, S.
