Habitat: Prefers open woodland, forest edges and semiarid areas.
Likes tree cover and often forages where humans live.
Wild Status: These cockatoos are becoming more rare in the
wild due to trade. They prefer to be in small groups or pairs. They
are difficult to see in the wild except when in flight.
Natural diet: Seeds, fruits, berries, nuts and flowers. They
also raid cultivated areas for easy pickings.
Aviculture: These parrots are noisy, with a harsh call and
repeated screech. Extremely hard chewers, provide plenty of wood for
chewing as often they will chew the wire meshing. They are also prone
to feather plucking if bored.
Accommodation: Outside flight: 15 x 6 x 6 ft (5 x 2x 2 m) provide
a shelter. Protect from frost and provide thick walled roosting boxes
of hardwood 12 x 12 x 40 inches (30 x 30 x100cm). Only use heavy gauge
wire mesh as these cockatoos are very destructive.
Diet: Good parrot mix including: sunflower, pumpkin seeds,
small seed mix (safflower, millet, hemp, oats, wheat), pine and other
nuts plenty of fruit and vegetables including apples, peas, greenfood;
and vitamin and mineral supplements.
in Aviculture: They need
to be kept in pairs in a large aviary. When males are in breeding
condition they may become very aggressive to their females. If they
are kept in too small an aviary the male may even kill the female.
Pairs don't breed before they reach their fourth year. Clutches usually
2-3 eggs maximum 5; incubation around 24 days and fledging takes 8-10
weeks. Remember to remove their young at the right time as the male
can attack the young. It is possible to achieve two breedings in one
As a Pet:
Cockatoos need lots of attention and make the best pets if they have
been hand-reared. One thing that should always be remembered with
these parrots is that they can be extremely noisy. They are not noted
for their talking abilities but may manage a few phrases. Generally
they need a lot of time with their owner. If you work, they will not
be a suitable pet as they require a lot of fuss and attention. They
can become very noisy if they don't get their own way.
