While stationed at Melaleuca in the extreme SW of Tasmania for two weeks last 
year My wife and I 
regularly had our observation stints for Orange-bellied Parrots interrupted by 
the local Grey Shrike 
Thrushes which were also breeding at the time.
The feeding table set up for observing the parrots was of course attractive to 
other birds (especially 
some Tassie endemics) and the GST's were observed removing the larger seeds 
(sunflower) and 
breaking them on the spot or taking them away to bash on some harder object.  
Other species seen 
to do this were Forest Ravens (Corvus tasmanicus), and Starlings (Sturnus 
vulgaris), although these 
weren't observed breaking the husks off seeds.  It wasn't apparent whether this 
behaviour was learnt or 
not.  However, both members of the local pair displayed the behaviour.
Has anyone observed evidence of apparently learned (feeding) behaviour passed 
on as a result of 
observing conspecifics in other Australian birds?
