16 February 1788 An alligator, ab’t 8 feet long, was seen close by where I go to birdlime just behind the camp, and has been seen among the tents at night more than once.— Arthur Bowes Smyth, Journal, HRNSW (2), 394.

One of my favourite picnic haunts is a clearing, close to a
stream, surrounded by smooth-barked apples.
At least half of that name is self-explanatory, although the tree is a
relative of the gum, and certainly bears no apples. The smooth pale bark of these trees is a perfect
place to go detecting, looking for signs of previous climbers. No possum can climb up to its nesting hollow
without leaving scratches, no bird can perch on a low branch without leaving
claw marks, and no goanna can climb, looking for eggs, without leaving signs of
its passing.
Goannas are varanid lizards, members of a group that is
mainly in Australia, but found also across Asia and Africa. Their most famous member is undoubtedly the
Komodo dragon of Indonesia, which is about 3 metres long, and able to attack
children or sleeping adults. We used to
have an even bigger giant varanid in Australia, up until 30 000 years ago,
about 7 metres long, but the biggest Australian varanid today is only about 2
metres in length, and much less fearsome.
Mind you, that was enough to convince the early white
settlers that there were ‘alligators’ around Sydney, and just recently, an
alarmed tourist claimed to have seen a ‘crocodile’, probably at my favourite
picnic site, but it was only a goanna, an old friend that we greet each time we
stop by there. Goannas are carrion
eaters, and I suspect that it makes quite a good living from discarded scraps
and from people like us, who feed it deliberately.
The goannas are supposed to get their name from a fancied
resemblance to iguanas, a completely unrelated bunch of reptiles, but they are
themselves, all 25 species in Australia, along with the other fifteen or so,
scattered around the world. You can find
them scattered right across Australia.
A goanna on the prowl has a slightly evil look to it. They walk with their upper leg joints held
out horizontally, and there is an almost calculated threat in the way each foot
is lifted, rolled around, and placed on the ground, like a sailor swaggering
down the street. The goanna holds its
head high, then lowers it to the ground, moving it from side to side, and it
flicks its tongue in and out, tasting the air to see what may be on offer.

For a slow-moving menace, the goanna has an amazing turn of
speed when it is threatened. It rushes
at the nearest tree, and hurls itself up the trunk, moving quickly to the far
side of the tree. Walk around to the
other side of the tree, and the goanna will move with you, keeping a handy
barrier of timber between you and it.
Goannas do not trust humans more than they have to. Except in open country that is. Frighten a goanna on a treeless piece of
ground, and you may find yourself playing the part of a tree. Avoid this if you can, for all tree climbing
animals have sharp claws.
A treed goanna may be persuaded to leave its shelter,
provided a reasonable offer is made to it.
Anybody who has ever kept poultry in Australia will know that there is
one thing a goanna cannot resist: the chance to get its muzzle dripping in
egg. Put a hen's egg at the bottom of
the tree, stand back about six to eight metres, and hunger will soon overcome
its sense of distrust.
Turning around on a narrow tree trunk ought to be something
of a challenge for something as long as a human, but not for the goanna. Deftly, it turns from head-up to head-down,
and stealthily approaches the egg, watching its watchers as it comes.
Goannas use their tongues only to sense things, and never to
eat, so the feeding goanna needs to slip the egg into its mouth before crushing
it. If ever a reptile could be said to
exhibit sheer sensual pleasure, it would have to be a goanna, sitting at the
base of a tree, with traces of egg white and yolk dribbling down from its
mouth.
You can find them close to homes, but they usually move away. |
Many Australians accept without question that the goanna is
an evil animal. They will assure you
that goanna bites ‘come back’ each year for seven years after you have been
bitten, that they are venomous or worse.
Some Australians will make every effort to run over a goanna, believing
that they are protecting the cuddly birds by doing so. They have been conditioned to this by
children's stories, and by a judgement based on appearances rather than
knowledge.
In truth, a goanna bite might go septic on you, for they are
great eaters of carrion. Certainly they
take a few eggs, but they also take lizards, snakes, and other
invertebrates. However you look at it,
their reputation for evil is greatly exaggerated.
Many years ago, I worked as a ranger in a local National
Park. There was a large goanna in the
park which was in the habit of basking on a rock, just below a lookout. We park workers would often time our labours
so that we were near the lookout at lunchtime, so we could take our break
there, looking out over the sea and admiring ‘our’ goanna. Looking back, it was unwise, but we got into
the habit of sharing small bits of our sandwiches with our friend the
goanna. We would show our goanna to
people, and encourage them to share suitable food with it as well. After all, it was a carrion eater, so a dead
sandwich would be no worse than any other dead thing, we thought.

Our goanna did not die entirely in vain, for I managed to
explain in gentle factual terms to any questioners that this was an old friend,
done to death most foully, and to no purpose.
I would add that we would at least be able to investigate its stomach
contents to see what it had been eating, and I probably won a few hearts and
minds that day. I did not mention that
we would probably find sandwiches as a major item.
I like winning hearts and minds to good causes. It is something I do well, and I have no
qualms about using whatever subterfuges and histrionics are needed to achieve
my ends. And while I feel that the ends
properly justify the means, looking back, I cannot help wishing that I had not
had the necessary means that day.
