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.
