Robert:  I assume you are not describing normal foraging behaviour in
that the bird flits from branchlet to branchlet while looking under leaves
and branches for insects. Is this correct?  It is common for thornbills 
here in Brisbane to hang upside down for short durations.  Are you saying
that the bird "stops" to perch but then falls over and hangs freely?  If
so, it would appear that it has a problem.  How long did you watch it?
What plant was it perched on?   What is "Shane"? 

Cheers, Jim Davis
