I am just writing to add some thoughts and observations about Galahs chewing bark. Galahs have been known to ringbark trees with their chewing.  They have been known to chew away the bark of trees that they intend on nesting in and one theory is that they do this to stop goannas from steeling the eggs from the nest.  They will chew away the bark below where the nest or proposed nest is located. The removal of the bark would make the trunk smoother thereby making it harder for goannas to reach the nests.
This is a theory that my father was told after Galahs had ringbarked a few trees on his property which is located just outside Tamworth. Any thoughts are welcome and I would be interested to hear more about the trees that Galahs have been see chewing in.
