The facts on


southern


cassowaries


Southern cassowaries are normally shy and harmless rainforest
birds. But during territorial disputes or when threatened, they’ll strike
out with their feet. They have a sharp elongated claw on each foot
capable of killing a large animal.

Lama Lama, Umpila and Wik-Mungkan of the Coen region
of Cape York Peninsula; and the nine Indigenous groups rep-
resented by the Girringun Aboriginal Corporation, whose lands
lie between Mission Beach and Townsville. Several of these
groups are now involved in cassowary conservation, using tra-
ditional ecological knowledge in concert with modern science.
Known as Kutini to the people around Coen, and Gunduy
or Gundulu to some groups further south, cassowaries are inte-
gral to Dreamtime narratives and traditional lore, and feature
in stories, ceremonies and dances. Cassowaries were also once
a valuable food source and played an important role in rain-
forest seed d isper sa l, helping to ensure a const a nt supply of new
fruit for people to forage.
Tim Jaffer, executive director of Kalan Enterprises, which
represents traditional owners around Coen, says that when they
began to think a decade ago about how best to manage the land
recently returned to them, one focus was the rainforest uplands
of the McIlwraith Range. “It’s where the creeks come from
and the rivers f low out of that [to] join the country up,” he says.
“Lots of bush materials are collected in the rainforest and there’s
lots of wildlife there and cultural stories associated with those
animals. The southern cassowary is one of them.”
Working alongside scientists such as David, Kalan rangers
have been involved in 15 or more field trips over six years that
have prov ided a n est i m ate of 170 – 40 0 ca ssowa r ies i n the ra nge.

SCIENTIFIC NAME: Casuarius casuarius
Originally derived from the Malay “kesuari”,
which comes from the Papuan words “kasu”,
meaning horned, and “weri”, meaning head.

SIZE: Adults grow to 2m tall; males weigh up
to 55kg and females up to 76kg. The heaviest
ever recorded weighed 85kg.

BREEDING: Cassowaries mate in
June–October. Females lay
clutches of 3–5 pale-green eggs
2–3 months later. Males brood
these for a further 50 days before
they hatch.

CHILDCARE: It was once thought
males did all the parenting, but there
are increasing accounts of females visiting
males and chicks.

DIET: Cassowaries have been
recorded to feed on at least
238 different plants. They
prefer fallen fruits, but will also
eat flowers and mushrooms as
well as snails, insects, fish,
crabs and other small animals.

FEATHERS: Cassowary feathers
differ from those of other birds in
that they lack tiny barbules to hold
feathers in shape and have a central quill that’s
split down the middle.

TERRITORY: Documented ranges
vary between 52ha and 235ha,
but can be much bigger.

ORIGINAL POPULATION SIZE: Based on the
amount of habitat lost in the Wet Tropics,
the cassowary population may have been
up to twice its current size before
European colonisation.

SEED DISPERSAL: By eating
rainforest fruits, cassowaries
play a major role in the dispersal
of seeds. In particular, they
are important for large-seeded
plant species.

FEET: Cassowaries have
dagger-like claws that can be up
to 12cm long, on the central of
the three toes on each foot.
When threatened, they can use
these to defend themselves,
jumping and kicking forwards
with both feet.
