Bird Overview

Being shy, secretive birds, Western Bristlebirds are seldom seen as they generally stay concealed among the dense vegetation of coastal heathlands. Although they are generally quiet, their distinctive high-pitched, melodious song is sometimes heard as they call from the ground, a low perch or occasionally the tops of shrubs.

Threats to the species

  1. Climate change

    Long-term changes in temperature, rainfall, sea levels, and extreme weather that alter habitats, food availability, breeding success, and survival. 
  2. Habitat destruction

    The permanent loss or severe degradation of natural habitat due to land clearing, urban development, agriculture, mining, or infrastructure. 
  3. Invasive species
