COCKATOO
Bird: Galah or Rose-breasted
Cockatoo
(Eolophus roseicapillus)
Range:
Australia, chiefly the interior and excluding wetter
coastal areas. Ranges to King Island and Tasmania;
although accidental in Tasmania. Found in open country
areas with scattered trees and riverine woodlands
Size:
Small dove sized parrot.
Length: 35 cm
Wingspan: Male 26 - 28 cm ; Female 25 - 28 cm (~ 1
ft.)
Tail: Male 14 - 16 cm ; Female 14 - 17 cm
Weight: 300 - 370 g
Diet:
Seeds, grain, roots, green shoots, leaf buds, and insects
and their larvae.
Description:
Adult's forehead, crown, and occiput are white with
a pink suffusion through the bases of the feathers.
The upper parts are grey, very pale on the rump and
secondary wing coverts. The face, neck, and most of
the underparts, including the underwing coverts, are
rose-pink. The lower abdomen and vent are pale grey,
the tail is dark grey, and the naked periophthalmic
ring is dark greyish red. The bill is horn colored,
the iris is dark brown in males and pinkish red in
females, and the legs are grey.
Natural History:
They are usually seen in small flocks, but large flocks
of up to 1000 are common. They occasionally associate
with other cockatoos and, when feeding with Sulphur
Crested Cockatoos, respond to that bird's sentinel
warning systems. They spend many hours in the morning
and late afternoon feeding on the ground. During the
heat of the day, they find shelter in a tree or bush,
idley stripping leaves and bark. Galahs are abundant
in most types of open country habitat below 1250 m.
They have benefited from land clearance and the cultivation
of cereal crops, and now are becoming plentiful in
coastal and mountainous areas. They are common in many
urban districts, even nesting in trees in gardens and
parklands. Nests are usually made in a hollow in a
eucalypt 2 - 20 m above the ground, but may also be
on cliff ledges. Both parents build the nest and 2
- 6 white eggs are laid. Both parents incubate for
approximately 25 days and young fledge in 7 - 8 weeks.
Galahs pair for life and may live for over 40 years.

Bird: Lesser Sulphur-crested
Cockatoo
(Cacatua sulphurea) 
Range:
Six subspecies can be found on the islands of Corubus and adjacent Buron Island.
Also found on the Sunda Islands, islands in the Flores and Java Seas, and in
Indonesia. Introduced in Singapore. Found in forest edge, woodland, farmland,
and coconut palm habitats.
Size:
Length: 38 - 51 cm
Wingspan: 22 - 27 cm
Weight: 300 - 400 g
Diet:
Seeds, nuts, berries, and fruits.
Description:
A medium sized white cockatoo with a huge, striking, forward curving yellow erectile
crest and yellow suffusion on the underside of the wings and at the base of the
tail. The feathers of the forecrown and above the eye are white and the folded
crest shows only as an upward curving yellow protrusion from the nape. The bases
of the feathers around the cheeks and throat are also yellowish. The eye ring
is pale blue to white, there is a slight yellowish suffusion on the ear coverts,
and the bill is blackish grey. The iris is dark brown to black in males and dark
red in females, and the legs are dark grey.
Natural History:
These birds are chiefly sedentary, but local movements have been recorded. They
are seen in pairs or small flocks and they are found mainly in tree tops, but
will come to the ground. Flocks use a sentinel warning system in which one or
more frequently changed lookouts raises the alarm with screeches if danger arises.
During the alarm call, the crest is raised and other species feeding in the area
also respond. They are most active just after dawn and nest in natural tree hollows
3 - 30 m above the ground. These natural hollows may be in tall eucalypts, cavities
in limestone cliffs, or hay bales in a barn depending on the region. They may
nest communally. Usually, 3 white eggs are laid on decayed debris at the bottom
of the nesting hollow. Both parents incubate for about 30 days and young fledge
in approximately 6 - 9 weeks. Young often return to roost in the nest hollow
for an additional 2 weeks after fledging.
Personal History:
Pogo - Has been performing in shows since 1986, carrying his strong environmental
message. He has become a crowd favorite at shows all over the country. He was
obtained by NEI in 1982 at 8 years old.

Bird: Palm Cockatoo
(Probosciger aterrimus)
Other names include Cape York Cockatoo, Great Palm
Cockatoo, Black Macaw, Great Black Cockatoo, and Goliath
Cockatoo.
Range:
Found in the lowlands of New Guinea, some related islands,
and in the northern Cape York Peninsula, Queensland,
Australia. Occurs in the Aru Islands, the western Papuan
Islands, and on the islands in Geelvink Bay. Previously
introduced to Kai Kecil and still present in 1981,
but now possibly extinct there. In New Guinea, the
species ranges through lowlands to 1300 m, but is commonest
below 750 m. On the Cape York Peninsula, it ranges
south to the Archer River in the west and to Princess
Charlotte Bay in the east. In New Guinea, the species
is found in rainforest, gallery forest, forest edge,
monsoon woodland, tall secondary growth, partly cleared
areas, and locally in dense savanna. In Australia,
they are found in forest, dense savanna woodland, and
eucalyptus and paperbark woodland adjacent to rainforest.
Size:
Length: 51 - 64 cm
Wingspan: 70 - 100 cm
Weight: 500-1200g
Diet:
Feed on large hard seeds of forest trees, palm nuts,
leaf buds, fruits, and berries. Nuts are cut in half
with the massive sharp-edged bill, and debris often
falls from feeding trees. They are primarily arboreal
feeders, but commonly feed on fallen nuts, seeds, and
fruits on the ground.
Description:
This bird is a huge-billed all black cockatoo with
a large crest and red facial skin. The adult's general
plumage is grayish-black. The forehead and lores are
black, the naked cheek patches are crimson, and the
bare thighs are bluish-grey. When alarmed, the color
of the cheek patch can darken to a deep red. The exposed
gape is red, the tongue is red with a black tip, the
bill is grey-black, the iris is dark brown, the periophthalmic
ring is grey, and the legs are grey. The head has an
erectile crest of elongate, up to 15 cm, feathers.
The mandible and maxillary do not fit when closed,
leaving the bi-colored tongue showing. The upper mandible
is appreciably smaller in the female than in the male.
Also, the bare patch of facial skin is smaller in the
female. In immature birds, the feathers of the underwing
coverts and underparts are edged with pale yellow.
In very young birds under 18 months old, the bill tip
and eye ring are white.
Natural History:
Their large size, black coloration, and piercing call
notes make this species very conspicuous. Singly, in
pairs, or in small groups, they are usually seen perched
atop tall trees or flying above the forest canopy.
They roost singly in the topmost branches of tall trees,
nearly always in the dead or leafless uppermost branches
of deciduous trees growing at the edge of rainforest.
They become active about an hour after sunrise and
will commence calling to each other. Shortly, up to
6 or 7 individuals will congregate in a large tree
in open woodland. The parties will leave the trees
and feed in open woodland or along the edges of rainforest
and will return to the individual roosting trees just
before sunset. The frequently heard contact call is
a disyllabic whistle; the first note is mellow and
deep, while the second is shrill and high-pitched,
being prolonged and terminating with an abrupt, upward
inflection. When alarmed, a sharp, gutteral screech
is heard. Other calls include a deep, monosyllabic
whistle repeated 3 or 4 times and a mournful, drawn-out,
wailing cry. The flight is slow, straight, and level,
with several slow flaps followed by a short glide,
and the large bill is held down against the breast.
On short flights, birds will periodically glide on
down curved wings. In courtship displays, the male
and female face each other with erect crests, stamp
and bow, and their facial skin turns a deep red. The
male may strike a branch with a stick, seed, or stone,
while calling with his wings spread, as a territorial
display close to the nest site. Nests are made in a
hollow limb or hole in a high tree, usually in the
trunk of a dead tree. The bottom of the hollow is lined
with a layer of splintered twigs which are carried
into the nest as long pieces and then split and broken
into short pieces. This feature is unique to this species
of cockatoo. The stick layer is porous and may be several
feet deep in some hollows, but only a few inches deep
in others. It is thought that this layer is designed
to prevent the eggs or chicks from being submerged
during monsoonal rains. One broadly elliptical, dull
white egg is layed on the layer. The female incubates
for 30 - 35 days and chicks fledge at 100 - 110 days.
After leaving the nest, the chick is fed by the parents
for approximately 6 more weeks. This species is under
pressure from habitat loss, trade, and reportedly hunting
in the vicinity of human habitation in New Guinea;
a common method being to fire arrows smeared with sticky
resin at roosting birds. The Palm Cockatoo is listed
in CITES Appendix I as near-threatened.
Personal History:
Palmer - Acquired by NEI in 1999 at under a year old.
