Had the pleasure of coming across these somewhat uncommon birds in the Mallee region of S.A. Found I could not get a clear shot in the thick scrub so tried a little experiment that worked nicely.
I scratched around in the sandy leaf litter in a more open area to imitate what the bird was doing in hope to get it's interest. After 5 minutes of this I stood back 15 feet with the camera and waited. It didn't take long before the Robin scurried over to my scratchings and started finding tidbits in the freshly turned earth. Gave me a good opportunity to rattle off several images at close range.
