I wonder if anyone knows why Little Corellas are forming into the huge flocks 
that cause devastation to trees.

I have experienced it a number of times over the years in both the east and 
west of Australia. Last year at Millstream-Chichester NP in WA, the ranger 
closed the campground when hundreds of Little Corellas descended on the 
Crossing Pool campground breaking branches off the melaleucas which littered 
cars, tents, tables, etc.  He was afraid that someone would suffer an eye 

Over the years on a farm out of Biloela, the Corellas have visited some apple 
gums surrounding a waterhole where they broke off all the branches.  These 
trees seem to regenerate each year so it hasn't been a problem.  However, this 
year they have attacked a large poinciana tree on the same property and 
completely denuded it to the extent where the owner is afraid it will die.

It appears they do not select one particular type of tree.  They just seem to 
break off the last 45 cms (18 inches) of each branch until there are no leaves 
left.   I would be interested to hear if anyone has any theories on the subject.
