Sombre Leaf-warbler

Phylloscopus amoenus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Sombre Leaf-warbler faces severe pressure from rapid deforestation and habitat conversion throughout its limited range in Southeast Asian montane forests. Agricultural expansion, particularly for palm oil plantations and subsistence farming, has fragmented its specialized high-altitude forest habitat. Climate change poses an additional threat by shifting temperature and precipitation patterns in the montane zones where this species depends on specific insect prey availability.

Threat summary

Habitat

The Sombre Leaf-warbler inhabits primary and secondary montane forests at elevations between 900-2,100 meters across Southeast Asia. It prefers dense canopy areas with rich understory vegetation where it forages for insects among the foliage of both native and introduced tree species.
