Distinguishing Features: The bright yellow rump is sufficient alone to distinguish this species from others in SA. But this may not be visible if the Bird is facing the camera. In that case look for the black forehead with white spots, and dark eye stripe. In the right light, the grey/brown of the eye is visible. Most easily confused with Acanthiza reguloides (Buff-rumped Thornbill) which has a buff forehead and clear white eye.
ID practice: Review the observations from SA and look for these features in the photos.
Distinguishing Features: Look for the chestnut crown with white streaks. Heavy streaking on the chin, throat and chest. In the right light, the grey/brown of the eye is visible. Most easily confused with Acanthiza pusilla (Brown Thornbill), which has a reddish-brown forehead scalloped with paler markings and red eye.
