Justification This species is a habitat specialist, occuring within a moderately small range, and numbers are suspected to be declining owing to habitat loss and degradation. These declines are not thought to be severe, but the situation could rapidly worsen in the event of any future increases in human pressure, so the species is classified as Near Threatened.

Range & population Psilorhamphus guttatus in south-east Brazil (Espírito Santo and Minas Gerais south to Paraná), and at lower elevations in north-east Argentina (Misiones)^4,5. It is rare to locally uncommon⁵, but probably overlooked because it rarely sings and has retiring habits.

Ecology: This species inhabits lowland humid forest and secondary woodland up to 900 m. As its English name indicates, it is mostly confined to large stands of bamboo⁵, but also occurs in vine tangles and other dense vegetation away from bamboo³.

Threats Agricultural conversion and deforestation for mining and plantation production historically threatened its lowland forests. Current key threats are urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building^1,2.

Conservation measures proposed Conduct surveys of suitable habitats within and surrounding the known range to determine its true distribution and abundance. Conduct ecological studies to determine this species's precise habitat requirements. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community led multiple use areas.
