I recently observed a group of Noisy Miners catching Brown 
shield-bug/stink-bugs on the base of a Eucalyptus tree at Murwillumbah NSW. 
What followed was interesting as the birds gave the bugs a good hiding with 
their beaks on the ground then proceeded to vigorously rub the bugs under their 
wings before discarding them. This behaviour with 7 Miners went on for ~ 20 
minutes. I checked the activity area when the birds left and found many wounded 
bugs and observed a pungent stink-bug odour.  Maybe, as suspected with 
"anting", the birds were de-lousing? Any similar observations from birders?
