Find a nice hollow branch of appropriate length and thickness, clean
it up, make a mouthpiece out of resin and decorate.
Most large 'gum' trees of age are hollowed out by termites (white-
anted). They eat the dead wood at the core and don't touch the live
wood on the outside. Interestingly, this makes the tree stronger - a
tube is stronger than a rod. Also the hollow trunks are habitat for
bats, usually after the termite mud galleries are washed out (mud
guts) and a fire or two has opened it up. 40% of forest large species
use tree hollows as habitat - parrots and possums in particular
usually where a branch has broken away and allowed rot to work down
the hollowed stump. Each animal has it's preference for opening size,
shape and angle.
The process takes around a hundred years for a fully mature habitat
tree, which is why logging on an 80 year cycle (or 60 in Tasmania!)
is a bloody disaster.
