Distribution in the Americas

Found strictly in the eastern region of South America, Tangara argyrofenges is endemic to eastern slopes of the Andes Mountains, spanning Ecuador, Peru, and Bolivia (Ridgely and Tudor 1989, Fjeldsa and Krabbe 1990). While their distribution spans three countries, they are found sparsely and disjunctly across this range (Parker et al. 1996). Generally this species is drawn to the yungas on the eastern slopes of the Andes due to the lush forests, but they can be found in areas close to dryer, elevated cities as well (Moynihan 1979). In Bolivia, this species is most commonly encountered between 1,600-1,900 m altitudes in the yungas, in the departments of La Paz, Cochabamba and Santa Cruz (Meyer de Schauensee 1966, Moynihan 1979). Birdwatching guides for this area recommend the Villa Tunari-Cochabamba Road through the yungas as a particularly unique place to see Green-throated Tanagers (Wheatley 1995). In Peru, this species is most abundant between 1,100 -2,200 m altitudes, particularly in eastern regions of the country, the Amazonas and San Martin (Meyer de Schauensee 1966). A few records have indicated their presence as far south as Paso and Junin in central Peru, though these are less frequent sightings (Schulenberg et al. 2007). The species is less common in Ecuador. Tangara argyrofenges is found from 1,350-1,600 m altitudes in Ecuador, however no major cities or areas of concentration have been identified (Birdlife International 2014). In general, their elevation ranges from 1,200 -2,700 m (Parker et al. 1996).

Due to its resident nature, T. argyrofenges does not have separate breeding and nonbreeding ranges, nor does it have a migratory zone (Skutch 1989, Restall et al. 2007). The center of elevational abundance for this species is in the middle montane zone (Parker et al. 1996). This species occurs in the Central Andes Zoogeographic Region (Parker et al. 1996).

Distribution outside the Americas

Endemic to the Americas.

Habitat

Green-throated Tanager is found primarily in terrestrial systems, specifically subtropical to tropical regions with extensive vegetation, namely forests, although details on their distribution are poorly understood (Parker et al. 1996, Restall et al. 2006, Birdlife International 2014). Parker et al. (1996) lists the primary habitat as montane evergreen forests occurring above 1,000 m altitude, which are primarily defined by their profusion of mosses and other epiphytes that cover most trees. Additional habitats used by this species include the following, in decreasing order of importance: canopy, forest edges, and mature secondary growth (Restall et al. 2006, Hilty 2011). One account from the eastern slopes of the Andes in remote southeastern Zamora-Chinchipe (Panguri) reported presence of T. argyrofenges in the canopy and borders of lower subtropical forest, with no entry into secondary growth (Ridgely and Greenfield 2001b).
