Australia's most spectacular bird would have to be the cassowary,
up to two metres tall, covered in coarse black double stranded feathers,
and with brilliant colors of red and blue on its neck and head. This
elusive flightless bird is highly endangered and lives only in the
Wet Tropics area of North Queensland and another patch of remote rainforest
high up on the Cape York peninsula.
The cassowary (Casuarius casuarius johnsonii) has been wandering around
this planet since before the super continent Gondwana broke up in
to several continents, and they have relatives in several distant
continents. They belong to a family of birds called ratites and are
related to the Emu, the Ostrich, the Kiwi (though there is a dramatic
difference in size) and the South American Rhea - a little known bird
that resembles a small emu and runs around plains in Patagonia. They
are also related to the now extinct Moas of New Zealand and the Elephant
Bird of Madagascar. In New Guinea there are two other species of cassowary
too but in Australia the only species is the Southern Cassowary.
Cassowaries (genus Casuarius) are frugivorous; fallen fruit and fruit
on low branches is the mainstay of their diet. They also eat fungi,
insects, frogs, spiders, snakes and other small animals, even dead
ones and roadkills. They live for about 40-50 years. They are the
second-largest bird in Australia and the third-largest remaining bird
in the world (the ostrich and emu are larger). "Cassowary"
originates from the Malay name kesuari.

The birds grow to 1.5 - 1.8 m tall, though the females are larger
and can reach 2 m and they weigh about 60 kilograms, but the heaviest
recorded was 83kg. They have a bony casque on the head that is used
to batter through underbrush, this is made of keratin, the same material
as our nails and hair. The casque is also used for headbutting and
some people believe it is used to receive the very low frequency humming
noise that they can make.

Usually cassowaries are very shy but when they feel threatened or
want to protect their young they can lash out dangerously with their
powerful legs and jump and kick with both legs at once. Their three-toed
feet have sharp claws; the dagger-like middle claw is 12 cm long.
Cassowaries are very capable of killing dogs by disemboweling them
and have injured people, though only one death has been recorded,
more on this on cassowary
attacks. They can run up to 50 km/h and jump up to 1.5 m. They
are also good swimmers.

They don't have much of a family life, they are solitary
birds but females will cruise around the forest mating with
several males during the breeding season from May to November.
Courtship is initiated by the male when a female enters his
territory. The smaller sized male must approach the larger
female with caution because if she is not in the mood she
is capable of seriously injuring him. The male begins courtship
by circling around the female and making a low rumbling sound.
When she has laid her eggs, three to eight, measuring about
90 by 140 mm and pale green-blue in color, in a shallow scrape
in the ground in which the male has placed leaves and grass,
she moves on again to repeat the process with another male.
It is the male's duty to incubate the eggs for about fifty
days and also to care for the chicks for another year or so.
The chicks are striped until they are about 6-9 months old
and become a glossy black colour when they are about 3 years
old. By that time, the skin on the neck and head begins to
turn color, and the casque begins to develop. Cassowaries
are capable of breeding when they are three years old.
Cassowaries are crucial to the survival of the rainforest, as many
of the seeds are too big to be dispersed by any other birds. The cassowary
eats about 150 different ones. Cassowaries swallow fruit whole and
then excrete intact fruit seeds in large piles of dung which acts
as a ready-made fertiliser, the dung helps the seed to grow. White-tailed
rats, bush rats, melomys and musky rat-kangaroos sometimes feast on
seeds in cassowary droppings. But most seeds survive to germinate.
Usually, seeds are deposited within a kilometre of where they were
eaten.
The total population of cassowaries in Australia is estimated
to be around the 1500, they are endangered and declared a
protected species. The main problems for them are;
- loss of habitat through clearing for
residential settlement and agricultural expansion (nowadays
everyone thinks the rainforest starts at the DaIntree river,
it used to start hundreds of kilometres further south before
the introduction of sugarcane)
- fragmentation of habitat ( from roads,
farms and subdivisions)
- vehicle traffic (road kills are the number
one cause of adult cassowary deaths, especially around the
Mission Beach area),
- dogs (which are especially aggressive to
chicks and juveniles)
- feral pigs - they compete for food with
cassowaries and chew the seeds so they will not be dispersed
and germinated like when they pass through a cassowary
- Some birds are still being shot and eaten

This 'before and after' bit of artwork is situated along the
road to Cape Tribulation.
It’s best not to stop if you see a Cassowary on the
road, but to slow down instead. This is to prevent encouragement
of the bird’s interest in cars and to reduce its risk
of being hit or causing an accident.
Do not feed a Cassowary as this reinforces its interest in
people and contributes to its fearless attitude.
When driving near a Cassowary, move away quickly so the bird
will become disinterested.
