Overview

The ash-browed spinetail is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Colombia, Ecuador, and Peru.

The Ash-browed Spinetail faces significant pressure from habitat loss and fragmentation due to deforestation, agricultural expansion, and urban development throughout its range in South American montane forests. Climate change poses additional risks by altering the temperature and precipitation patterns of its specialized high-altitude habitats. The species' restricted range and specific habitat requirements make it particularly vulnerable to these ongoing environmental pressures.

Threat summary

Habitat

Inhabits humid montane forests, cloud forests, and forest edges at elevations typically between 1,500-3,000 meters in the Andes. The species shows preference for dense understory vegetation and bamboo thickets within these high-altitude forest ecosystems.
