The Vilcabambabuschammer ( Atlapetes terborghi ) is a little researched songbird species from the genus of the bushhammer ( Atlapetes ). It occurs in the Cusco region in the Peruvian Andes . The type epithet honors John Terborgh , who collected the type specimens .
features
The Vilcabambabuschammer reaches a body length of 17 cm. It is a dark species with a yellow underside. The area from the top of the head to the nape of the neck is reddish, with the forehead being the darkest. The face, including the reins, the over-eye stripes, and the ear covers are blackish. The top is blackish with an olive wash that extends from the back to the upper tail-coverts. The rump area is more olive in color. The upper wings and the tail are blackish. The tail feathers have olive colored hems. The underside is yellow from the throat to the under tail-coverts. The chest and flanks have a greenish tinge. The iris is dark brown. The beak is black. The legs are blackish. The sexes look the same. The juvenile birds are undescribed.
Occurrence
The Vilcabambabuschammer is east of the Cordillera de Vilcabamba Río Apurímac in the west of Cusco region in southern Peru endemic .
Habitat and way of life
The Vilcabambabuschammer inhabits moist mountain rainforests and elven forests at altitudes of 2520 to 3520 m. The specimens collected in July were ready to breed, suggesting that the breeding season is during the dry season . Nothing is known about the way of life of the Vilcabambabuschammer.
Systematics
In July 1967 John Terborgh and John Seddon Weske collected the five type specimens of the Vilcabambabuschammer, which were described in 1993 by James V. Remsen as a subspecies of the Red-necked Bushhammer ( Atlapetes rufinucha ). In a mitochondrial DNA sequence analysis, Jaime García-Moreno and Jon Fjeldså demonstrated in 1999 that the Vilcabambabuschammer is a valid, independent species and that their closest relatives are the black- rimmed bushhammer ( Atlapetes melanopsis ), the slate bushhammer ( Atlapetes canigenis ) and the Black-faced bushhammer ( Atlapetes melanolaemus ) are.
