Classification of Cockatoos
Cockatoos (the Cacatuidae family)
Subfamily Microglossinae
The Palm Cockatoo, is a large black parrot. It measures over 25 inches and can weigh as much
as 3 pounds It is found in the large tracts rain forests and woodlands of New Guinea and in the north
of Australia. The Palm Cockatoo is the only cockatoo that uses the tropical rain forest habitat.,The
other cockatoos species prefer drier forest habitats. The Palm Cockatoo is unable to excavates nests
in trees and they look for existing cavities in large trees. Because of their large size the Palm
Cockatoos require wide hollows and these can only be found in the larger trees, i.e., old trees. Although
the Palm Cockatoo is not endangered at present, one can readily see that the clearing of old trees
in the rain forest would certainly disturb its nesting habits. It is not known if the Palm Cockatoo could
adapt to severe changes in its nesting habitats. Also the Palm does face some competition from
other wildlife for these very same hollows. Although deforestation presents a clear threat to them one
cannot discount the ravages caused by seasonal fires in their nesting grounds.
The Palm Cockatoo is a rather lonely bird and it spends most of i ts time foraging for seeds, nuts, fruit, berries, and leaf buds.
. It has sufficient nesting, foraging and roosting habitats to meet its requirements at present. It is a fairly common bird. Its population is stable and
has not faced any severe declines in the past decade.,and thus it is not on the endangered species list. It is not commonly kept as a pet parrot
This species is unique in its kind and the only member of this subfamily.

Subfamily Calyptorhynchinae - dark cockatoos (Callocephalon genus)
Gang-gang Cockatoo is found in cool humid tall mountain forests and sub alpine woodlands of Australia, and on occasion in temperate rain
forests., In winter it is found mainly in the more open eucalypt forests and woodlands, and there it gathers in fairly large flocks of about 50 birds.
Unlike the other cockatoo it shows a marked preference for young trees when it comes to nesting habitats. The clearing of forests does reduces its
abundant foraging, nesting and roosting habitats but the gang gang still has a large enough range for its habitat requirements. With a population
of over 20,000 in the wild it is considered to be a common bird., It is not on the endangered species list. It is not commonly kept as a pet but it does
make for a good pet parrot.
the Cockatiel is a little cockatoo endemic to Australia and is a common household pet. In
the wild, it is normally found in the outback using the scrub lands, wetlands and
bush lands. They are always found near water and sometimes feared by farmers as they
can also be crop pests. The cockatiel has a very large range and plenty of nesting and foraging
habitats.
the Calyptorhynchus genus
Calyptorhynchus-sub genus (black-and-red cockatoos)
Red-tailed Black Cockatoo, aka Bank's Black Cockatoo has a large foraging, nesting and
roosting range at present. It is native to the north and west parts of Australia .They are usually seen in very
noisy small flocks. The Red Tailed Cockatoo is a common bird (100,000 plus individuals), and in the northern
part of Australia the farmers often consider it to be a crop pest. Is has a wide variety of habitats ranging from
dry open forests to rain forests. They have a wide range at present with abundant nesting, foraging and roosting
habitats.
However the Red Tailed Cockatoo is very dependent on old and large eucalyptus trees for their nesting hollows
and the loss of old trees in their native forests could definitely affect their reproduction in the future. The
disappearance of the old trees would also means the disappearance of the one of their preferred food, namely
the seeds of the eucalypt fruits. So their continued survival is thought to depend on the presence and
maintenance of these old large eucalypt trees. At present there is no shortage of food supply or nesting habitats
for these birds.
An interesting fact about these parrots is the price they command on the pet market. A Red Tailed Cockatoo
can fetch tens of thousands of dollars in America. Like other Australian Cockatoos, The Red Tailed is very
vulnerable to the illegal bird trade and bird smuggling, and the illegal poaching of eggs and baby chicks for aviculture.

The Glossy Black Cockatoo, aka the Casuarina Black Cockatoo is found in Australia. It is very similar to the Red Tailed Cockatoo.As a temperate
species the Glossy Black Cockatoo lives in coastal woodlands and drier forest areas, open inland woodlands or timbered watercourses where it is
always close to Sheoaks and the associated eucalypt forests., The Glossy Black Cockatoo feeds for 6-7 hours a day exclusively on the very hard
seeds of Sheoak trees and that is all it eats It is estimated that the birds spend at least 88 per cent of their time foraging for food. It is very selective
in its choice of foods. It chooses Sheoaks that produce seeds that have high value nutrients. They require high quality Sheoaks woodlands for
foraging. In addition, they need large eucalypts with large hollows for nesting and roosting. It is not endangered at present but its dependence on
sheoks and eucalypts makes it a very vulnerable bird.
The clearing of sheoaks trees has resulted in an endangered listing for a subspecies of the Glossy Black Cockatoo namely the
C. l. halmaturinus subspecies. This subspecies has disappeared from mainland Australia and is now confined to Kangaroo Island. This species
has a population estimate of roughly 300 individuals at present Preservation efforts are in place at this time and it is recognized that their survival is
totally dependent upon Sheoaks for food and eucalypts for roosting and nesting habitats. Other factors threatening their survival are the predation of
eggs and young chicks by feral cats and possums that raid their nests.

Zanda sub genus -(black-and-yellow/white cockatoos)
The Yellow-tailed Black Cockatoo is from to the south-east of Australia It is the largest cockatoo. It is found mainly in coastal areas, eucalyptus
woodlands. Its survive on a diet of seeds from pines and sheoaks as well as larvae. Its range is very wide but it too is dependent on old eucalypts
for nesting and roosting.. It has a large and stable population of over 20,000 individuals at present. They are very noisy and conspicuous birds
gathering in flocks of 100s.
Short-billed Black Cockatoo, aka the Large Black cockatoo is endemic to south-western Australia. It is on the endangered list even though its
population is estimated at 40,000 plus individuals. The reason being that in spite of its large numbesr its total population has shown a steady
decline over the past decade. In fact its breeding population has decreased by as much as 30%.. Its breeding success depends upon its feeding
area being no more than 12 kms away from its nesting habitat. Like most of the cockatoos it nest in the hollows of eucalypts and its feeding areas
near the eucalypts has been cleared for agricultural purposes and thus rendering its feeding habitat very patchy. The unwanted result of this being
that It has been known to cause some damage to nearby orchards by foraging for nuts and tree shoots.
It forages for food usually in woodland, shrubland and heathland where pine plantations have an become important feeding and roosting areas. It
feed on seeds of many trees , seeds of weed., exotic pines, nectar and larvae. Preservation effort were put in place by the Australian government
and the main focus is to preserve their nesting and roosting areas as well as preserving their foraging habitats.

Long-billed Black Cockatoo,or White-tailed Black Cockatoo occurs in the south-west of Western Australia It is classified as a near threatened
species. Even though its population numbers about 15,000 individuals, still the species has vanished from one quarter of its range. Also it is
thought that only 10% of these birds are breeding. Its range is restricted to humid and heavily forested areas. It too is dependent on eucalypts for
nesting, feeding and roosting. A large area of its range has been cleared for agriculture and logging for eucalypts for woodchips, furniture and
whatnots have all contributed to the reduction of foraging and nesting trees for this bird.
Some conservation measures and forest management efforts have been implemented such as the preservation of eucalypts, and the control of
the feral bees that were seen occupying the tree hollows necessary to this bird's nesting.

There is about 350 species of parrots and they belong to the order of the Psittaciformes .They
are grouped into two families: the Psittacidae (true parrots) and the Cacatuidae (cockatoos).
are grouped into two families: the Psittacidae (true parrots) and the Cacatuidae (cockatoos).
The Cacatuidae family
There are 21 species of cockatoos. They differ from true parrots in that they have head crests, and gall bladders They also
lack Dyck texture feather composition which accounts for the bright blue and green colours generally observed on in true
parrot. Generally, they are also larger than true parrots The range of the Cockatoos is far more restricted than that of the true
parrot seeing that they are normally found pnly in Australia and the nearby islands..Of the 21 species, 11 are found in the
wild only in Australia. Many classes of Cockatoos command a very high market price and that makes them very vulnerable to
capture, smuggling and poaching of their chicks for the pet trade. The trade of cockatoos bred in captivity is permitted. But
they can only be sold with CITES certificates which prove that they were bred on captivity..

Cacatuinae subfamily- white cockatoos (Genus Cacatua)
Sub genus Cacatua (true white cockatoos)
Major Mitchell's Cockatoo or Pink cockatoo restricted to arid and semi-arid inland areas of Australia where it occupies cleared and
semi-cleared areas.. It is recognised as the most beautiful of all cockatoos. The Pink Cpckatoos requires extensive woodlands and it too favours
eucalypts for nesting and roosting as well as sheoaks for foraging. It has large range at present and it is a common bird. With a large and stable
population it is not on the endangered species list.
the Sulphur-crested Cockatoo is very popular as a pet parrot.. These birds have a very wide range all across Australia, and are very
numerous. They have also been successfully introduced to Singapore where their numbers have been estimated to be between 500 and 2000
individuals.
Yellow-crested Cockatoo, aka Lesser Sulphur-crested Cockatoo is found in Timor-Leste and Indonesia's islands of Bali, Timor, Sulawesi and
Lesser Sunda Islands. The Yellow-crested Cockatoo is on the critically endangered list. This cockatoo has seen its population decline very
rapidly by as much as 80% over three generations largely due to the pet trade. Sumba houses the largest remaining population present (maybe
3000 birds) but it is rapidly declining . The bird is found in a wide range of habitats including forests, forest edges and, scrub lands
There is a feral population of these parrots in Hong Kong.
http://www.cityparrots.org/2007/07/28/cockatoos-of-honk-kong/
Citron-crested Cockatoo,it is distributed and endemic to Sumba .The Citron-crested Cockatoo is classified as critically endangered.. Its decline
is due to habitat loss and illegal pet trade They inhabit open woodlands, the edges of forests, and cultivated wheat fields It usually gather in
small groups and has a varied diet requirement in the wild. The Citron-Crested Cockatoo is a small cockatoo measuring 13 inches long. This
cockatoo is being excessively trapped for the pet trade and that is the major contributing factor to its placement on the endangered species list.
Blue-eyed Cockatoo,The Blue-eyed Cockatoo is distributed and endemic New Britain Papua, New Guinea where it has a fairly wide range. It is
found in lowland rain forests. It is on the near threatened list at present. It has a population of aver 10,000 at present. It is not known what
percentage of that population is breeding however. But like the other cockatoos who rely on large trees for nesting and breeding conversion of
forests to plantations has caused a significant decrease in the foraging, nesting and breeding habitats of these birds.

The Moluccan Cockatoo aka Salmon-crested is endemic to south Moluccas in eastern Indonesia.. It is found mainly in the lowland rain forest.
The total population number over 60,000 individual at present, however this birds has been trapped a great deal for export for the pet trade. It is
now on the endangered species list . It is estimated that in the 80s about 75,000 birds were exported from Indonesia. It is now thought that
about 4000 birds are trapped from the wild each year. It also faces some persecution from farmers who consider it to be a crop pest in some
areas.

The Umbrella Cockatoo, aka the White Cockatoo is an Indonesian bird found in humid lowlands, mangroves and plantations. In the 90S
this parrots was quite common with a population of perhaps as many as 100.000 individuals. Its foraging and nesting range has decreased
however, and this bird is extremely vulnerable to pet trade activities. In the 90s at some point it was estimated that over 6000 birds were captured
from the wild for the pet trade activities. At present it is on the Vulnerable list . But cockatoos have a high market value and thus they are always
vulnerable to capture and the poaching of their chicks for trade activities.

Sub genus Licmetis (corellas)
the Long-billed Corella is also native to Australia. These birds have excellent vocal abilities. It is not on the endangered list at present but
there has been a decline in their population. They are widespread throughout Australia. They gather in large flocks especially near water. They
also forage in large flocks. They tend to favour grain and grass seeds as their primary food stuff.
the Western Corella is endemic to Australia. It was once considered an agricultural pests largely because
this species eats grain. In the 1940s, there were only 100 of them but the laws prohibiting the shooting and
[poisoning of these birds and the agricultural developments proved beneficial to their survival and at present
they number 3000 or so individuals. Their population is said to be increasing.

the Little Corella, aka the Bare-eyed Cockatoo, is native to Australia and is very common in open woodlands. .It enjoys a very wide range for
foraging and nesting. It is a very common bird and its population is increasing. It is often regarded as a crop pest It gathers in very large flocks for
foraging in croplands especially..
The Red-vented Cockatoo is also called the Philippine Cockatoo. It is on the critically endangered
list. Its population has dwindled dramatically largely due to loss of their forest habitats and the pet trade.
They are generally nomadic and follow the food sources which vary with the seasons. This species was
once very common as recently as the 90s, but deforestation, bird killing to protect crops and the pet trade
all have contribute to a severe decline (as much as 90%) in its population. Much of its foraging and
nesting habitat has been removed.

the Goffin's Cockatoo,aka Tanimbar Cockatoo, is restricted to the Banda Sea Islands of Yamdena and Larat (Tanimbar). Its population is
estimated to number between 300-400,000 individuals. It has suffered some habitat loss on account of logging
and the pet trade. It is on the near threatened list at present. It mainly inhabits forests, and agricultural lands at
present and the latter may indicate that they are viewed as crop pests.

[poisoning of these birds and the agricultural developments proved beneficial to their survival and at present
they number 3000 or so individuals. Their population is said to be increasing.

list. Its population has dwindled dramatically largely due to loss of their forest habitats and the pet trade.
They are generally nomadic and follow the food sources which vary with the seasons. This species was
once very common as recently as the 90s, but deforestation, bird killing to protect crops and the pet trade
all have contribute to a severe decline (as much as 90%) in its population. Much of its foraging and
nesting habitat has been removed.
