HABITAT
Maleo
can be found in hot spring water areas, which are preferr ed for nest making.
There are seven places of maleo birds in Bogani Nani Wartabone National
Park ( Dumoga Bone National Park ) ; Ta mbun, matayangan, Muara Pusian,
Leda-Leda, Pohulongo, Pinomonue and Hungayono.
Outside
of the park there are also several places and the maleo can even be found
in coastal area. Maleo birds feed within a distance of 20 km around its
nesting area. Maleo birds which
were
tagged in Matayangan ( 1986 ) were nesting in Tambun ( 1991 ). The distance
of these two
places
is ± 25 km.
BEHAVIOUR
In general
maleo birds are similar with other aves. There are some differencies such
as ; maleo
could
not fly far away . They just fly from one tree to another.
Maleo
birds make a nest by digging a hole in sandy ground around hot springs
or in coral ground.
The chicks
cratch the sand to dig themselves out to the surface.According to scientific
reseach,
FOOD
Maleo
eats cereal, insect, also worms and snails. Based on reseach in the Dumoga
Bone National Park, the chicks could be domesticated and feeded on corn,
beans and peanuts.
PREDATOR
Predator
that hazard the population of maleo's birds are lizards, dogs and eagles.
Egg collection by the local population in threatening the birds much
more than its natural predators.
Together,
male and female dig the hole by take in turn. According to the studies
of this birds, every pair digs nesting hole in different depth depending
on the appropriate temperature. The deepest hole is around 1.5 metres.
Commonly, temperature, where maleo lays their eggs, is around
- 35 Celcius . Each hole contains one egg. They lay the
egg in vertical way which the sharp
size
to the buttom. At the last part of the nesting process, maleo birds close
again the hole with sand. Then they leave the egg without breeding it.
The breeding season last from October to April. The female products about
15 eggs per a year. The egg need 60 - 80 days for hatch. There is
an unique behaviour of baby maleo in the hatching process.
the
chicks need one day for creeping out from the bottom of the hole, and then
they take a rest
for
5 minutes before being able to fly around for about 15 metres. This is
the time for a chick to struggle in a new life
in the forest.
