In winter they migrate to lower elevations of up to 400 meters. They prefer open terrain with secondary vegetation and groups of trees in wooded valleys. They are often seen near running water. Every now and then they climb up into the Polylepis forests. Its distribution area extends in Bolivia to the departments of La Paz , Cochabamba , the west of Santa Cruz , Chuquisaca and Tarija . According to censuses by BirdLife International , they were recorded in the Cordillera de Sama Biological Reserve , the Tariquía National Fauna and Flora Conservation Area, and the Tunari National Park .

behavior

You see the brown beard bushhammer mostly in pairs. They look for seeds and insects in dense undergrowth, on moss-covered trunks or thick branches. Sometimes they climb around upside down. You may see them on the ground, but this is rare. As soon as they sense danger, twitch their tail and chirp an alarming pi ziue . Otherwise their singing is a repeating thin zit . In Jujuy they breed in January.

Research history and etymology

D'Orbigny and Lafresnaye used the taxon Emberiza fulviceps in their first description . Only later was the bird categorized in the genus Atlapetes . The word Atlapetes for the genus is made up of atla for the Titan Atlas , whose name means bearer, patient and petes from the Greek petros for rock . In ancient mythology, Atlas carried the vault of heaven on his shoulders. The specific epithet fulviceps is derived from the Latin word fulvous for yellow-brown .
