Distribution in the Americas

The Silvery Tanager occurs in the Andes of Ecuador, Peru and Bolivia (Isler and Isler 1987, Hennessey et al. 2003, Restall et al. 2007) on both the west and east slopes (Isler and Isler 1987, Ridgely and Tudor 1989, Restall et al. 2007, Schulenberg et al. 2007). This species has been found at elevations as low as 800 m to as high as 3050 m, but usually occurs  from 1500 to 2500 m (Parker et al. 1996, Schulenberg et al. 2007, Restall et al. 2007). In southern Ecuador, the species occurs in the provinces of El Oro, Loja and Azuay. In Peru, south on the west slope to Lambayeque and southern Cajamarca and on the east slope from the Amazonas to Puno (Ridgely and Tudor 1989). Distribution in Peru of Tangara viridicollis. Solid circles: specimen records; open circles; sight records; dotted line: 1000 m contour (Schulenberg et al. 2006) In Bolivia the Silvery Tanager is known only from western La Paz, Bolivia (Hennessey et al. 2003, Ridgely and Tudor 2009).

The species that are closely related to the Silvery Tanager (Sira Tanager T. phillipsi, Green-throated Tanager T. argyrofenges, and Black-capped Tanager T. heinei) primarily are allopatric, although there is sympatry between viridicollis and argyrofenges in northern Peru. Otherwise, a single subadult viridicollis was netted with T. phillipsi in Cerros del Sira in Peru, but this bird was a possible wanderer (Graves and Weske 1987).

Distribution outside the Americas

The Silvery Tanager is endemic to South America.

Habitat

The main habitat of Silvery Tanager is humid montane forests, forests that are patchy, deciduous woodlands, and mostly second growth forests (Isler and Isler 1987, Ridgely and Tudor 1989, 2009, Fjeldså and Krabbe 1990). Parker et al. (1996) list the main habitats of this species as montane evergreen forest, tropical deciduous forest, and secondary forest. This species is rarely found inside continuous forest (Schulenberg 2007) and tends to be found on the edges of forests and stays around or near these borders when in a forest habitat (Isler and Isler 1987). Silvery Tanangers also visit shrubbery clearings with isolated trees or bushes (Ridgely and Tudor 2009, Isler and Isler 1987).
