Vicky Powys added to the Black Cockatoo discussion by writing:
"Yes, Yellow-tailed Black-Cockatoos will rip through tree trunks and branches.  If you have a closer look you might see where they have extracted wood boring grubs.  I once saw great "destruction" of a patch of snow gums, branches were on the ground everywhere, all chewed off by the cockies, but you could also see the hollow groove in the fallen branch where the grub had been chewing, and that's what the cockies were after........."
Please send some Yellow-tailed Black Cockatoos to my place! 
One by one my shrubs and small trees are being victimised by wood boring grubs.  Whilst the allocasuarina verticillatas, correas - reflexa, alba & pulchella -  and westringia fructicosas usually carry on growing regardless of the devastation caused by the grub a strong gust of wind causes the shrub to break at the weakened spot.   Apart from crying what can I do when this happens?
