Synallaxis courseni
The Apurimac Spinetail (Synallaxis courseni) is a remarkably localized and enigmatic member of the Furnariidae family, endemic to the dry intermontane valleys of south-central Peru. This small, drab passerine measures approximately 17 cm (6.7 inches) in length and weighs about 15-20 grams, making it a relatively compact spinetail. Its plumage is characterized by a mostly olive-brown back and flanks, a distinctive reddish-brown crown, and striking rufous lesser and median wing coverts, which f...
This species inhabits arid scrub, thorny thickets, and dry deciduous woodland, often found along riparian zones and steep slopes within intermontane valleys. It primarily occurs at elevations ranging from 1,700 to 3,100 meters (5,600-10,200 feet) above sea level.
Its diet consists primarily of small invertebrates, including insects such as beetles, ants, and caterpillars, along with spiders. It forages by gleaning prey from leaves, twigs, and bark within dense shrubbery.
The Apurimac Spinetail is a highly secretive and inconspicuous bird, typically observed alone or in pairs, diligently foraging within the dense undergrowth and lower strata of its thorny habitat. It is diurnal but often difficult to spot, preferring to move quickly and acrobatically through tangl...
The Apurimac Spinetail is strictly endemic to a limited region of south-central Peru, primarily inhabiting the dry intermontane valleys of the ApurÃmac River drainage. Its distribution spans parts of the Ayacucho and Cusco departments, where it occupies a fragmented network of suitable arid scrub...
