Species Profile
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.
Key Facts
