Distribution in the Americas

Cinereous Conebill is found from southernmost Colombia, south to northernmost Chile and central Bolivia. It has a broad elevational range, from sea level up to 4500 m (Fjeldså and Krabbe 1990), and at least occasionally to 4750 m in Peru (Benham et al. 2011). In Colombia, it occurs from 2600-3600 m (Hilty and Brown 1986); in Ecuador from 2300-4000 m (Ridgely and Greenfield 2001a); and in Bolivia mainly from 2600-4050 m (Herzog et al. 2016).

Interestingly there are two ecological zones C. cinereum inhabits. In the eastern Andean highlands (ca 2100-4000 m), it is found near tree-line in dry to moderately humid zones, especially bushy woodland borders, patches of dense stunted shrubbery, gardens and other lightly wooded drier habitats, and also in Polylepis woodland. The birds of the coastal desert and arid west slope of the Andes (sea level up to ca 4500 m) occur in shrubby sites, riparian thickets, gardens, scrubby vegetation on slopes, and riparian vegetation along dry streambeds (Jaramillo 2011).

Distribution outside the Americas

Endemic to South America.

Habitat

Interestingly there are two ecological zones that Cinereous Conebill inhabits. Although cinereum and fraseri are restricted to the Humid Temperate Zone, littorale inhabits arid to semi-humid areas of both Temperate and Tropical zones. In the eastern Andean highlands (ca 2100-4000 m; subspecies fraseri and cinereum), Cinereous Conebill is found near tree-line in dry to moderately humid zones, especially bushy woodland borders, patches of dense stunted shrubbery, gardens and other lightly wooded drier habitats, and also in Polylepis woodland. The birds of the coastal desert and arid west slope of the Andes (sea level up to ca 4500 m; subspecies littorale) occur in shrubby sites, riparian thickets, gardens, scrubby vegetation on slopes, and riparian vegetation along dry streambeds (Jaramillo 2011).

Historical changes

Cinereous Conebill occurs in such a wide variety of habitats, and it is therefore difficult to assess historical changes to its habitat. It is likely not especially sensitive to disturbance, as it occurs in heavily modified environments in many parts of its range. However, it does require woody vegetation, a habitat that has been steadily declining in the high Andes over the past several centuries due to human activities (Bush et al. 2005). Throughout the Northern and Central Andes, woody vegetation is cleared to make room for farmland and grazing pastures (Andersen et al. 1999). It is possible this widespread activity may have caused a reduction in suitable habitat for the species. See also Effects of human activity on populations.
