It measures 30-35 centimeters to paste 380 g..
The Solomons cockatoo(Cacatua ducorpsii) is a small cockatoo immediately recognizable by its long triangular Crest.
Its plumage is almost completely white, except the part inferior of them wings and tail with infiltration of color yellow. The feathers of the crest, the cheeks, the the mantle and the chest they have a base of pink.
The bill is grey. The bare skin around the eyes is pale-blue. The irises are dark brown, the legs grey.
The females are distinguished from your partner to have the irises more reddish.
The Solomons cockatoo is quite similar to the Tanimbar corella living in the Tanimbar Islands. Also seems to the Little corella, although the latter have more bluish and developed the orbital area.
Is from coastal areas to the mountains; variety of habitats, including forests, secondary vegetation and gardens in cities. Found up to 1700m; mainly below the 700 m.
Behavior:
They are birds noisy and quite easy to observe, even though they mostly live in pairs or small groups. They fly high above the treetops where used well exposed perches in the top of the Cup.
Birds are very cautious, screaming when they are disturbed.
They have a strong and uneven consisting of shallow flapping flight.
Reproduction:
In the wild child from July to September.
They make their nests in hollows of trees or large branches and, they often use the same nest year after year.
The eggs are of color white and usually there are two in a clutch. The eggs are incubated for about 25 days, the young leave the nest 62 days after hatching.
Food:
They feed on seeds, berries, fruit, outbreaks, flowers, as well as insects and their larvae. From time to time they ingest the fleshy parts of ยซepiphytesยซ.
Distribution:
endemic to the Solomon Islands. Its area of distribution extends from Bougainville (Papua New Guinea) to Malaita, Choiseul, New Georgia and Santa Isabel. The species is absent in San Cristรณbal and the islands surrounding.
Conservation:
State of conservation โ
Minor Concern โ(UICN)โ
– Current IUCN Red List category: Least concern.
– The population trend: Stable
The population world is estimated at 100.000 birds and it seems quite stable.
The marketing of pet birds is a threat to this species, the other is the degradation of the habitat. The latter seems particularly serious, given the logging of forests in the lowlands.
"Solomons cockatoo" in captivity:
Itรยดs little gregarious and have tendency to be aggressive with other species and with those of its same species. In relation to the human being is a Parrot very demanding. Not everyone is prepared to have a white cockatoo.
They often tend to develop behavior problems, unbearable screams, become very destructive…If not are given a rigorous education on a very regular basis. That is why it is convenient that if you intend to have a cockatoo, it should be done so that it can be accompanied by another or others of its kind to prevent it from developing an excessive dependency and thus you can enjoy it without fear of having problems or at least trying to avoid them as much as possible.
I like them much attention. They tend to create strong emotional bonds and they are quite Extrovert.
Despite the great attraction that having a pet parrot with such characteristics can mean for a person,. It is not often a parrot advised for anyone or rather, hardly anyone is prepared to have a cockatoo with these characteristics.

The Tanimbar corella(Cacatua goffiniana), like all family members Cacatuidae, is a species crestada, meaning it has a collection of feathers on its head which can go up or down at will; his body is covered with white feathers with some feathers or salmon pink between bill and eyes.
The deepest parts of the feathers of the crest and of the neck They are also the pink, but the color is hidden by the white color of the more superficial. The bottom of its wings and feathers of the tail They have a yellowish hue. The bill It is pale gray and eyes range from brown to black.
There is a clear sexual dimorphism and, often, merge with the blood cockatoo(Cacatua sanguinea) due to their similar appearance.
Riparian forests, thickets of acacias and eucalyptus with short grass or pasture with scattered groups of trees.
Reproduction:
The start is two to three eggs, generally deposited in the hollow of a tree. The incubation, that is shared by two birds, lasts a few 30 days. The chicks they leave the nest about ten weeks after hatching, and feeding by the parents continues for another few weeks.
Size of the area of distribution (reproduction / resident): 9.100 km2
The Tanimbar Cockatoo It is a species of cockatoo endemic to the forests of Yamdena, Larat and Selaru, all the islands of the Tanimbar Islands of Indonesian. This species has been introduced in the Kai Islands, Indonesian, Puerto Rico and Mexico.
Conservation:
State of conservation โ
Near Threatened โ(UICN)โ
โข Current IUCN Red List category: Near-threatened.
โข Population trend: Decreasing.
In the Decade of 1970, Japanese loggers ravaged the Islands. Many birds were stunned and disoriented and were captured for pet trade. Although many died from stress during transport, there is still some hope after this ecological disaster, since many cockatoos managed to reproduce in the programs of captive breeding. So, there are now more specimens in captivity than in their natural habitat.
This species has a range very small, but its population is severely fragmented or restricted to a few places. Despite suffering from the pressure of his capture, seems to have maintained a large population. But, the degradation of the habitat, trapping and continuous persecution is likely to be causing a moderate reduction of the population. Therefore it is classified as Near-threatened.
There is a conservation plan in endemic parrots Tanimbar Islands, Indonesian, financed by LORO PARQUE FUNDACIรN
"Tanimbar corella" in captivity:
You can show a fearful beginning, but you quickly get used to their caregiver, turning into a very cockatoo sweet, playful, sometimes inquisitive and very active. Enjoy being observed, being the center of the world, like all cockatoos. His cry is not nice, but this little cockatoo is quickly forgiven everything as his antics and bad manners will surprise us and make us laugh.
Has the continuing need to fly so you need a large space.
Curiosities:
A Tanimbar corella, without previous training, open five types different locks:
The incredible mechanical intelligence of the Tanimbar cockatoos 1
It measures 31 cm. and weighs around 300 g..
To the Philippine cockatoo(Cacatua haematuropygia) It is called locally Katala.
Its plumage is of a beautiful white color except for the feathers of the crest they are yellow or pink on its base and the bottom of the tail and wings they are yellow and Red.
The bill is a grayish-white color, and males has irises dark brown, While the of the female are brown-red color.
Is restricted to lowland not more than 50 meters above the sea level, in or adjacent to rivers, and in coastal mangrove areas.
outside the breeding season (March to June, and, times, from February to August), frequents corn and rice crops. This depends on the station where foods are grown and have the available resources, being partially nomadic.
These birds can fly from their island to the adjacent if they are not more than a few 8 km. distance.
Reproduction:
breeding season between February and June. Of one to three eggs they are placed on a nest on a tree branch. The eggs are hatch for a few 28 days, and the chicks remain in the nest for nine to ten weeks after the hatching.
Food:
They feed on seeds, vegetables, fruits and berries.
They are known to attack corn crops in agricultural areas.
Distribution:
Size of the area of distribution (reproduction / resident): 22.700 km2
This cockatoo is endemic in Philippines, and the only representative of the cockatoos that we will find there; This has become a treasure of these islands.

critically endangered โ(UICN)โ
โข Current IUCN Red List category: Critical Hazard.
โข Population trend: Decreasing.
โข Population size: 370-770 mature individuals.
In Palawan the capture of the cockatoos for the international illegal trade is particularly serious, something which is reflected in the high price of these birds ($ 160 Americans in Manila in 1997); to have been looted all the visible nests each time the price is higher because it costs more to catch them.
The deforestation and the destruction of mangroves have been extensive in their range of occupancy and have contributed significantly to their decline.
It is also hunted and hunted for consumption as food.
The release of captive birds can introduce diseases into wild populations.
Conservation Actions Proposed:
โข Conduct surveys on all range islands to assess species population size and distribution.
โข Monitor population trends.
โข Monitor rates of habitat loss and degradation.
โข Quantify catch levels, persecution and trade.
โข Designate more protected areas (for example Tawi-Tawi and towns in or near Palawan).
โข Support the proposal to expand the Puerto Princesa Subterranean River National Park.
โข Prevent destruction of mangroves.
โข Promote economically viable alternatives to avoid the capture of this cockatoo.
โข Continue with education programs and captive breeding programs.
โข Establish staff at airports and ferry terminals to control the departure of specimens.
โข Translocate animals to suitable areas such as lowland forests or mangroves..
Loro Parque Foundation It has warned of the risk of extinction that runs the Philippine cockatoo by the construction of a power plant in Palawan, an island province of Philippines in the region of Western Visayas.
This Spanish NGO has invested 1,3 millions of dollars and more than 14 years of work in the recovery project of this cockatoo, and fears that with the construction of this station, the less than 1.000 remaining specimens in the world could be electrocuted by high-voltage lines, In addition to being blocked their migration in search of food.
The Yellow-crested cockatoo(Cacatua sulphurea) It is distinguished by its long, thin yellow erectile crest, that curves forward, and extending upward, above the nape, when it folded. The front of his crown and main feathers crest, are white. The rest of your plumage It is also white, except in yellow suffusion ear-coverts, under the wings and in the innerwebs of the undertail-coverts. The bases of the hackles and underparts, They are yellowed; some birds show a slight yellow tone, particularly on chest and the belly. The bill It is black; eye ring pale bluish; irises dark brown; legs grey. The female is similar to the male but with the irises reddish and slightly smaller.
The young birds They show both sexes irises dark taupe, although females They begin to acquire the red coloration in the first year. The bill and legs immature are also lighter.
(Oberholser, 1917) – Similar to the parvula, but largest.
Cacatua sulphurea citrinocristata
Cacatua sulphurea citrinocristata
(Fraser, 1844) – Slightly larger than the nominal, with one crest orange & ear-coverts orange yellow. Additional research may provide a basis for improving this subspecies to a specific status..
Cacatua sulphurea parvula
(Bonaparte, 1850) – Similar to the nominal species, but with the ear-coverts paler and less yellow on yellow feathers underparts. the size of the bill in this subspecies it increases clinically towards the west.
They inhabit at the edges of the forest, wooded areas, farmland, cocoteros, semi-arid areas and forests until the 800 m (locally 1.200 m).
The Yellow-crested cockatoo usually they found in pairs or small groups of up to ten individuals, although they may meet in larger flocks to feed on fruit trees. They can form flocks with Eclectus Parrot(Eclectus roratus).
They tend to be noisy and visible, but can be difficult to spot when moving silently in the canopy, and they are more often in flight. The groups who leave their resting places in the montane forest areas frequently displace forage at lower altitudes including cultivated fields. Pairs may hover conspicuously above the forest canopy searching for fruitful trees, allowing a reasonably close approach when resting on a branch.
The crest It is generally stands when landing, or when an individual is making calls from a perch. Like most of the Cockatoos They enjoy a bath in the rain.
Reproduction:
Specimens of Yellow-crested cockatoo on the island of button in State reproductive during the months of September and October, although Nusa Tenggara the breeding It occurs in the months of April and May. The female It lays two or three white eggs in the hollow of a tree, and incubation lasts around 28 days with both parents participating. Chicks they leave the nest to 10 weeks and are dependent parent for about two months.
Food:
They feed in trees and soil. Its diet It includes seeds, corn (Zea mays) of cultivated fields, fruit, berries, egg yolks, flowers and nuts (including large coconuts (cocos nucifera)).
Distribution and status:
Size of its range (breeding/resident ): 1.360.000 km2
The Yellow-crested cockatoo They are confined Indonesian, where they can be seen in the lowlands Isla Celebes (virtually extinct in the north), islands in the Flores sea, in Nusa Tenggara and isolated islands Masalembu in the Java Sea.
introduced in Singapore and Hong Kong. The species is found in both wooded areas and cultivated and is scarce throughout its range. It is estimated that the world population total is less than 40.000 birds and is decreasing. Although populations of the nominal subspecies and of the subspecies parvula may still be close to 10.000 specimens, the citrinocristata subspecies It has an estimated population between 800 and 7.200 only individuals, having declined by 80% between the years 1986 and 1989, while the distinctive subspecies abbotti It is now represented by only nine individuals in nature.
Although habitat loss is clearly a factor in Sumba, where distribution appears to be linked to the extent of primary forest (is only about 15% the original forest), trade is the main threat to the species as a whole. Trade data show that exported almost 100.000 birds in years 1980-1992. The export citrinocristata subspecies It was banned in 1992 by local authorities, and 26 birds were confiscated in September of that year. There are probably at least 50 individuals of each subspecies in public collections and more than 2.000 in private aviculture, although the numbers for the subspecies abbotti They are unknown.
(Fraser, 1844) – Sumba, where it can be seen in the remaining forest around left, or east of the island, where it may still be locally common; an expedition of the Manchester Metropolitan University found it common in the remaining forest areas in 1990, with the greatest discovery of birds, a group of five birds, found in primary forest near Tabundung
โข Current category of the Red List of the UICN: critically endangered.
โข Population trend: Decreasing.
Its crashing fall It is almost entirely attributable to the unsustainable exploitation for domestic and international trade. Logging to the conversion of forests for agriculture as well as the use of pesticides for land and large-scale.
Justification of the population
Based on recent surveys in various parts of the range of the species, C. Trainor in some (2007) It has been estimated the world population in less than 7.000 individuals: 3.200-5.000 en Sumba (though perhaps only 562 in 2012, Burung Indonesia en preparaciรณn), 500 en Komodo, 200-300 en Timor Leste, 200-300 en Sulawesi, 20-50 in West Timor, 40-70 Flores, 50-100 en Sumbawa, 100 in Rinca and other 700 birds in total. The best data is located in the band 2.500-9.999 individuals, equivalent to 1.667-6.666 mature individuals, rounded here to 1.500-7.000 mature individuals.
Conservation actions and research in progress
CITES Appendix I (2005). It has developed and adopted a recovery plan cooperative and has prepared an update 2012 (D. Mulyawati in some. 2012). The populations are found in various protected areas, It is the most important Rawa Aopa Watumohai (55 copies in 2011 [Waugh 2013]) and National Parks Caraente (en Sulawesi), supporting up 100 individuals (transgressed 2006) , Reserva Natural de Wildlife en Pulau Moyo, Komodo National Park and two national parks in Sumba: Manupeu-Tanadaru y Laiwangi-Wanggameti. Nini Konis Santana National Park declared in Timor has a 100 estimated birds (Trainor et al., Without date) . In Rawa Aopa Watumohai nests they have been protected from predators by removing vegetation pendant necklaces and installation of plastic around the tree trunks nesting (Waugh 2013). Moratoriums on international trade are in effect, although it is likely that a large proportion of trade is a national. Several subpopulations of Sulphur-crested Cockatoo have increased in Sumba between 1992 and 2002, due to conservation efforts (including local education, ecotourism and law enforcement), although densities remained below those typical for other cockatoo species (Cahill et al ., 2006) . Capture for trade has declined dramatically in Sumba through a variety of awareness and protection measures of the community (D. Mulyawati in some. 2012).
Following the surveys of 2008 and 2009, the Indonesia Parrot Project and Konservasi Kakatua Indonesia have started meetings with community leaders and villagers in Masakambing and Masalembu, as well as with the military and local police, to raise awareness and gain support for Sulphur-crested Cockatoo conservation (Metz et al. Al., 2009) . A conservation program-awareness-pride has also begun to involve adults and school Archipelago Masalembu (Metz et al. , 2009, Translating et al., 2009) And in Southeast Sulawesi (Anon., 2012). A "village regulation" was written to catch, possess or transport the species and initiate measures to reduce habitat destruction and employ a former village chief to guard and protect nests and study Sulphur-crested Cockatoos (Translating et al., 2009) . Moronone community in Rawa Aopa Watumohai NP, where four members of the village have been hired as Forest Wardens (Anon., 2012), have established similar community-based regulations. The guards protect the species against poachers and perform monitoring activities (Waugh 2013). The pest status of the species can be addressed by planting crops to compensate for losses and to act as a "sacrifice culture", for example, sunflower fields are used to attract the species out of other crops (Waugh 2013). Mangrove restoration is also being used to increase nesting habitat available (Waugh 2013). a repeat of the population census is planned abbotti , together with studies on its biological history and ecology (Metz et al., 2009) .
Proposed Research and Conservation Actions
Carry out further studies (including Roti, but also more studies on Alor and Pantar) to identify the most appropriate action for conservation areas and to periodically monitor key population surveys repeating ago 8-10 years. Provide relevant support for protected areas and conservation initiatives within its range and protect nests when possible. Strengthen the protection of forest Poronumbu, Sumba, declaring Nature Reserve (Translating y Agustina 2012). Strengthen control, the enforcement and monitoring of trade and establishing greater management of captive populations. Improve law enforcement in designated protected areas and other key areas for trade, including ports, markets, etc. Promote widespread community conservation initiatives. These may include, en la isla de Pasoso, Sulawesi Central, work to protect the Sulphur-crested Cockatoo should involve all five families living on the island and introduce community involvement programs for children and adults on several other islands where the species occurs (Translating y Agustina 2012). The recommendations formulated specifically for the protection of the species in the Komodo National Park consisted of carrying out an annual monitoring, maintain regular patrols, sensitize local communities and studying human activities and impacts within the park (Imansyah et al ., 2005, Benstead 2006) . Conduct ecological research to clarify options for management and conservation. Other objectives should be to study the abundance and distribution of nest holes and water sources.. The provision of artificial sources of water near the nesting sites, that is to say, water ponds, It is essential for the species on the island of Komodo and may also be necessary to protect the nests of young Komodo dragons in Komodo (Translating y Agustina, 2012).
"Yellow-crested cockatoo" in captivity:
The male Yellow-crested cockatoo It is especially aggressive with the female, sometimes to kill her. This phenomenon is known in many cockatoo species..
among the white cockatoos, this is somewhat difficult to breed in captivity. As a pet can be a formidable partner provided it has been raised for that purpose and to provide much attention.
It is very difficult for them to disconnect in the presence of their owners and entertain themselves without seeking continuous interaction.
Great ability to imitate human sound within the world of cockatoos.
Note: Because of its status, CRITICALLY ENDANGERED, only controlled captive breeding is recommended in an attempt to recover this species in the wild.
