This genus was traditionally placed with the Thrushes or the Babblers (Timaliidae), but is now considered to be more closely related to the rockfowl (genus Picathartes), and is placed in the monogeneric family Chaetopidae. Molecular evidence indicates that this family diverged from the main Passerine tree about 45 million years ago, before the divergence of the Passerida (into the superfamilies Muscicapoidea, Sylvioidea and Passeroidea).
Habitat
Steep rocky slopes with grass and bushes; scree.
Behaviour
Movement
Runs fast, but stops frequently, often cocking its tail.
