The Cotorrita Dorsinegra has a limited distribution in southeast Brazil, from Bay (three records in the nineteenth century) to the South of Sรฃo Paulo, leaping Espirito Santo (although presumably it is extinct there).
โข Current category of the Red List of the UICN: Vulnerable.
โข Population trend: Decreasing.
Population size : 2500-9999 specimens.
JJustification of the Red List category
It is likely that the population of this species is small and decreases, with small subpopulations. For these reasons, the species is classified as Vulnerable.
Justification of the population
The evaluation of the Brazilian Red List poultry (MMA 2014) It is estimated that there <10.000 individuos maduros con <1,000 individuos maduros en cada subpoblaciรณn.
Justification of trend
Se sospecha una decrease moderate and continuous of the population because rates of habitat destruction and degradation.

Description 2 subspecies:
Amazona vittata gracilipes โ
(Ridgway, 1915) – Extinct. Of smaller and with feet smaller and thinner than the species nominal.
The Puerto Rican Parrot formerly he frequented the main types of natural vegetation (various forest habitats, from mangroves to montane forests) in Puerto Rico, with the possible exception of dry forests in the southern coastal regions.
Its Current small population remainder inhabits the mountain rainforest to 200-600 m. In the lower mountain slopes dominated by trees tabonuco of the species Dacryodes excelsa, in swampy forests at higher elevations characterized by the abundance of Cyrilla racemiflora and areas Sierra palmPrestoea montana.
Observed in pairs or (especially when they fed) in small flocks, having formed, formerly, flocks of several hundred.
Reproduction:
The Amazona Puerto Rican nidifican in large and deep cavities of trees; in the past they put their nests in the limestone hollows, in the west of the island. The amazon of Luquillo usually nest in species Cyrilla racemiflora. They defend their territory aggressively in the vicinity of the nest while playing. The egg laying, between February and April, possibly to coincide with the availability of fruit. Clutch 2-4 eggs (usually three).
Since 2001, all nesting known in the wild they have occurred in artificial cavities (White et al ., 2006).
Food:
The diet of the Puerto Rican Parrot It consists of a variety of fruit, seeds, flowers and leaves, among which include fruit of Prestoea montana and Dacryodes excelsa, flowers of Piptocarpha tetrantha and bracts of Marcgravia sintenisii.
Distribution and status:
Size of its range (breeding/resident): 1.000 km2
The Puerto Rican Parrot It is endemic to Puerto Rico and the former neighboring islands Mona and Snake; there are reports of parrots Vieques and St Thomas, probably belonging to this species. Formerly found in all forested regions Puerto Rico (with the possible exception of dry coastal strip south), but from around 1960 their habitat was limited to the Luquillo forest, in the East.
drastic population decline and rank the mid-nineteenth century. The pre-European population was probably hundreds of thousands of birds. There was a dramatic decline, which it reduced its population to about 2.000 copies in 1937 and in 1950 they were only a 200: a search in 1968 only revealed the existence of 24 birds.
The conservation program, initiated in 1968, It includes captive breeding, the provision of nests, detailed investigation ecology and reproductive biology and the control predators and competitors.
In 1992 the wild population was 39-40 birds 58 in captivity (all in Puerto Rico). Its population has declined, to near extinction, mainly by habitat loss (in 1912 only 1% the virgin forests of the island they remained), the hunting and capture as pets. The continuing threats to the tiny remaining population include impact of hurricanes (wild population halved to 21-23 after the passage of birds hurricane Hugo in 1989), competition with introduced bees Apis mellifera by tree cavities, the loss of broods due to parasitic flies Philornis pici, losses caused by predators and competition for nesting cavities with Pearly-eyed Thrasher (Margarops fuscatus). The Puerto Rican Parrot, inhabitants of the Culebra island (dubiously separated as subspecies Amazona vittata gracilipes), extinguished early twentieth century, probably because of persecution due to damage of crops and the impacts of hurricanes. existing population protected inside of the El Yunque National Forest.
โข Current category of the Red List of the UICN: critically endangered.
โข Population trend: Increasing.
โข Population size: 33-47.
Rationale for the Red List category
Once you have done a count of birds, are only 13 Puerto Rican Parrot in the nature, leaving the species on the verge of extinction. The conservation action the population has increased from 1975, but remains critically endangered because the number of mature individuals is still minuscule. If the released birds breed successfully in nature and the figures remain stable or increase, the species can justify a change of state in the future.
Justification of the population
From 2011, the population was between 50-70 individuals divided into two areas, approximately equivalent to 33-47 mature individuals. In 2013, its population had only increased to 80-100 individuals in the nature (64-84 in Down river and 15-20 in The anvil). But, since the released birds are not counted as mature individuals until they have successfully bred in nature (UICN 2011), and the entire population of Down river It is derived from released birds. The total number of mature individuals is uncertain but may well be less than 50, therefore, estimating 2011 of mature is maintained in this figure.
Justification of trend
It is estimated that increase 1-19% has occurred in the last ten years, based on regular accounts of the total wild population.
Conservation Actions Underway
โข CITES Appendix I.
โข And Recovery Program the species has involved a partnership between the Fish and Wildlife of the United States, the Forest service of the United States and the World Wide Fund for Nature together with Department of Natural and Environmental Resources of Puerto Rico (White et al. 2012).
โข In 1968 an important intervention was initiated to preserve the species, the provision of artificial nests highly successful, the predator control nest and its competitors, and captive breeding and reintroduction.
โข The success of the Newborns parrots It monitored using radio telemetry (Meyers 1996).
โข All the rest of the habitat is protected in the El Yunque National Forest (above the Caribbean National Forest) (Snyder et to the., 2000) and in the Rio Abajo State Forest (T. White in a little.
โข The population is monitored to help inform management decisions.
โข The predator control exotic mammals (Entrapment and toxic bait) It has proven to be a highly profitable way to preserve the species (Engeman et al. 2003, 2006, R. M. Engeman in some. 2012).
โข Catch data have shown that the Luquillo Forest It has between densities black rat studied highest in the world and optimal strategies have been devised rat bait for application during the nesting.
โข Los economic analysis based on empirical costs of production of parrots raised in captivity showed very high cost-benefit ratios for predator management, estimating that preventing a loss of parrot each 4-12 years more than makes up all forms of predator management (for all species) intervention time (Engeman et al., 2003).
โข Hay two captive breeding centers, one The anvil which it was established for the first time 1973 with a new facility built in 2007 and one in Down river built in 1989 with the first birds transferred The anvil to Down river in 1993 (White et al 2012).
โข About 280 birds are currently in captivity in Down river and The anvil (T. White one bit., 2012).
โข Captive birds are being managed to preserve the greater genetic diversity possible.
โข A release technique known as precision release was tested with six birds in 2008. This involves the release of a small number of captive-reared subadult parrots into each active nest immediately after chick rearing., and it aims to promote the immediate and close interaction between wild parrots and birds released (T. White in a bit., 2005, 2008).
โข Nearly 100 birds have been released the aviary Down river in an attempt to establish a second population, which may be helped by a lower annual precipitation in the site, lower levels of predation and a change in management techniques (T. White in a little. ).
โข Although the after release mortality remains high, there has been a successful breeding and the size and range of the flock is increasing (Breining 2009, Valentin 2009, T. White in a little.)
โข The newly established population in Down river It is located around the site Aviary of Down river and it is believed that the presence of captive birds encouraged released birds to establish their population close (White et al., 2012).
โข Forty specimens were released in The anvil between 2000 and 2004, eight 2008 and six birds in 2010 (Velez-Valentin 2011). In 2013 plans were made to establish a third population on the island in the Maricao State Forest (West of Puerto Rico) (Anonymous 2014).
Conservation Actions Proposed
โข Continue to monitor population trends.
โข Follow the fate of released birds.
โข Maintain the integrated conservation management program.
โข Improve synchronization of breeding of wild and captive birds to increase the number of captive-bred chicks that can be fostered by wild parents. (Thompson 2004).
โข Integrate control of exotic mammal predators (black rat, small Indian mongoose, wild cats) in the management program and monitor existing conservation predator populations to study the effectiveness of these measures (R. M. Engeman in some. 2012).
The Puerto Rican Parrot in captivity:
According to sources, A copy of Puerto Rican Parrot lived 10,1 years in captivity. But, considering the longevity of similar species, likely maximum longevity is underestimated in this species. In fact, it has been reported that They can live up to 27,2 years in captivity, what it is plausible but has not been confirmed. Taking into account that the Cuban Parrot(Amazona leucocephala), closely related, You can live up 50 years (Wilson, et to the., 1995), an age close to the latter figure may be possible for the Puerto Rican Parrot.
Each captive specimen of this species which is capable of reproducing, must be placed in a well-managed captive breeding program and not sold as a pet, in order to ensure its long-term survival.

GEOGRAPHICAL VARIATION
Parrots eastern side of San Vicente They are possibly genetically isolated from the western side: the small bird population East (perhaps only about 80 in 1982) show a high proportion of green and have their high-pitched voices.
Sound of the St. Vincent Parrot.
Habitat:
Video "St. Vincent Parrot"
The St. Vincent Parrot They mainly inhabit mature moist forests in altitudes of 125 some 1000 m, although they prefer lowland forests, where they spend most time. Occasionally they leave the forest to visit cultivated areas and even gardens. gregarious and usually in groups 20-30 individuals or in pairs. They forage in flocks and roost use Community. They defend the area around the nest while breeding, although they also stay in groups while feeding and sleeping..
Reproduction:
Nests in hollow mature forest trees such as Dacryodes or Sloanea large. The pairs begin the breeding activity around February with the eggs laid between April-May.. In dry years, eggs can be deposited as soon as in January-February or as late as in July. If conditions are especially wet, birds can not be played at all. Clutch two eggs, rarely three. low productivity with 50% Natural suffering nest failure and successful nests with only two young people in the best years.
endemic to the San Vicente Island in the Lesser Antilles. The distribution is closely related to the presence of native humid forests that for most of the 20th century have been confined to the eastern and western sides of the central foothills of the island..
Currently the largest flocks of St. Vincent Parrot inhabit the headwaters of Buccament, Cumberland, Colonaire, Congo-Jennings-Perseverance and Richmond Valleyโs, where much of the remaining native forest concentrated; elsewhere in smaller numbers.
Some estimates of its population between 1870 and 1920 They are contradictory, but the species evidently decreased substantially 1950. Estimates of the population in the early seventies suggested that between several hundred to 1.000 then birds inhabited the island. Survey 1982 amounted to a total of 421 ยฑ 52 birds while estimating 1988 He suggested 440-500. Perhaps they increased to 800 birds in 1994. The declining population and shrinking range, is linked to the loss of moist forest cover that once (at least in the western side) almost reached sea level. Deforestation seems to have stopped in at least some valleys, but habitat remains at risk due to forestry, expansion of banana, charcoal production and loss of nests for collectors looking young birds for trade. Survey 1984 suggested that they only survived on 16 km2 of primary forest. His capture for pets and international trade It remains a threat, but this and hunting, that was probably the main threat from late 1950 to 1970, They have declined in importance following an education campaign. The remaining population is also at risk because of hurricanes that can cause loss of plants that consume and nesting sites, as well as direct mortality. In 1902 much of the favorite habitat of this species was destroyed by the eruption of Monte Soufriere and these parrots are clearly vulnerable to future volcanic eruptions. Parts of the remaining forest habitat are now protected areas and the species is protected under domestic law. CITES Appendix I.
Conservation:
State of conservation โ
Vulnerable โ(UICN)โ
โข Current category of the Red List of the UICN: Vulnerable.
โข Population trend: In increased.
โข Population size: 250-999
Rationale for the Red List category
Habitat conservation, Law enforcement and public awareness campaigns have slowed this species' slide toward extinction and even reversed some of the earlier declines.. But, still qualifies as Vulnerable because it has a very small population and range on one island.
Justification of the population
The species has a wild population of about 730 birds (Loro Parque Foundation 2008), which is equivalent to 487 mature individuals, placed here in the band of 250-999 individuals.
Justification of trend
The number of this species continues to steadily increase. (Culzac-Wilson 2005).
Threats
It hunting for food, capture for trade in birds in cages and habitat loss were the main causes of the decline of this species. Deforestation has been a result of forestry activities, expansion of banana, production of charcoal, loss of nesting trees felled by hunters looking young birds for trade, as well as natural disasters such as hurricanes and volcanic eruptions (Snyder et to the., 2000).
The nine-banded armadillo o negro tattoo (Salmo salar), introduced on the island, undermines large trees causing them to fall, reducing the number of suitable nests for the St. Vincent Parrot (Culzac-Wilson 2005). a highway is planned through the island, funded by the Taiwanese government, that would destroy large areas of suitable habitat and increase deforestation rates (Culzac-Wilson et al., 2003). Genetic isolation of separate subpopulations may be of greater concern.
Conservation Actions Underway
Appendices I and II CITES. national legislation protecting the species applies. The Reserve Pargo de San Vicente It was established to protect the entire habitat occupied (Juniper and Parr 1998). Successful public education campaigns have apparently improved public perception of the species and, combined with the above measures, They have reversed some of the earlier reductions. There captive populations San Vicente and Barbados (Woolcock 2000, Sweeney 2001). In 2005 a large species conservation plan published (Culzac-Wilson 2005) .
Conservation Actions Proposed
Continue to monitor the population. Continue and enhance existing security measures, including the development of the captive breeding program. Study the reproductive success, movement patterns and habitat requirements of this species (Snyder et to the., 2000) . Oppose plans for cross-country road and propose a better option. Implement species conservation plan.

Description Burrowing Parakeet subspecies
Cyanoliseus patagonus andinus
(Dabbene & Lillo, 1913) – Similar to the species nominal but it lacks the bright yellow belly with pale areas on the sides of chest and rump olive colored duller. This and subspecies Cyanoliseus patagonus conlara they have the upperwing-coverts more brown than the nominal species.
Cyanoliseus patagonus bloxami
(Olson, 1995) – Size larger than the nominal species (wings 250-263), upperparts, throat lower chest and dark brown; bill larger and heavier and patches creamy most extensive on the sides of chest (in some birds merge to form a band breast pale).
Cyanoliseus patagonus conlara
(nores & Yzurieta, 1983) – Breast darker than the other Argentine subspecies.
The species usually inhabit areas open pastures, although it has also been reported in Savanna, wooded valleys cliffs and farmland some 2.000 m. Usually in a fairly arid land, although often it found near elevations or streams. Gregarious, forming large flocks, sometimes exceeding 1.000 birds, with common roosts trees, on wiring (sometimes in villages) and in tunnels dug to nest.
Reproduction:
It reproduces colonially in warrens carved into cliffs (usually limestone or sandstone Chile) often with stunning views. In San Luis, Argentina, reproduction is reported in the wet season (NovemberรขโฌโApril), the birds return to nest in the cliffs lay eggs in September and November to December in San Luis, spreading of bird breeding sites in April; apparently earlier in Chile. Clutch 2-4 eggs. The male takes care of feeding the female during the incubation period.. The young leave the nest at 2 months of age, However, They continue to be fed by their parents until 6 months of age.
They were recorded in the early 1920 from the center of Formosa, Argentina, away from Andes mountains, and above the center Chile from the North of The lakes to north of Atacama, but now they are confined to a few localities in the foothills of the Andes, for example in Bio Bio.
Will produce some seasonal movements, including the northward migration of birds south in the Argentine winter and shifts down Chile.
In Argentina is locally common or abundant, although in some places (p. e.g.. in Cรณrdoba and Buenos Aires Eastern) They are rare or occasional. Few and far between in Uruguay. drastic decline during the twentieth century Chile, so that the subspecies Cyanoliseus patagonus bloxami It is considered at risk, with an estimated population of less than 3.000 individuals at the end of the decade 1980. The decrease in parts of the Argentina It is attributed to the catch for the trade, the hunting for food, converting grassland and arable land persecution as crop pest. Probably continues to decline overall.
Burrowing Parakeet subspecies distribution
Cyanoliseus patagonus andinus
(Dabbene & Lillo, 1913) – Northwest of Argentina in Catamarca, Tucumรกn, Salta, La Rioja, San Juan and Mendoza. Area of โโdistribution in relation to the nominal species unclear but apparent they are distributed by the center of Argentina
Cyanoliseus patagonus bloxami
(Olson, 1995) – Formerly burrowing parrot byroni. Formerly in the central provinces of Chile, now severely restricted
โข Current category of the Red List of the UICN: Least concern.
โข Population trend: Decreasing.
โข Population size : 95000 individuals.
Rationale for the Red List category
Even though the demographic trend It appears to be declining, the decline is not believed to be rapid enough to approach the Vulnerable thresholds based on demographic trend criteria (> 30% decrease in ten years or three generations). The population size is very large, and therefore does not approach the thresholds for Vulnerable under the criterion of population size (<10.000 individuos maduros con un descenso continuo estimado en >10% in ten years or three generations, or with a specific population structure). For these reasons, the species is evaluated as Least concern.
Justification of the population
The species is still common in many parts of its range in Argentina, with only small contractions reported in range Cรณrdoba (R. M. Fraga a slightly. 2003). The population size of four subspecies was estimated as follows by MASELLO et al. (2011): Cyanoliseus patagonus patagonus 43.330 nests, Cyanoliseus patagonus conlara 1.700 individuals, Cyanoliseus patagonus andinus 2.000 nests, Cyanoliseus patagonus bloxami 5.000-6.000 individuals. Based on these figures, the population Total overall can be about 95.000 mature individuals.
Justification trend
They suspected that the population is declining due to continuing habitat destruction and unsustainable levels of exploitation.
Threats
The species has been the subject of a intense trade: from 1981, year it was included in the Appendix II of the CITES, they have been 122.914 individuals caught in international trade (UNEP-WCMC CITES CITES Trade Database, January 2005).
Conservation actions underway
The species is included in the Appendix II of the CITES.

The Black-fronted Parakeet(Cyanoramphus zealandicus) They seemed to be very similar to the rest of the species of Cyanoramphus; They were olive green; the forecrown It was black; the lores (the regions between the eyes and the peak on the sides of the head of a bird) and stretches along the eyes They were red; the lower part of the back It was red; the uppertail-coverts red. the outerweb of the flight feather They were blue violet. The eye rings They were light blue. The adults probably had irises orange, while young birds had eyes dark or brown.
The legs They were brown and gray bill It was pale bluish gray with a blackish tip.
Habitat:
According to Des Murs (1845, 1849), Lt. M. J. Marolles shot three birds tahiti in 1844, in Port Phaeton, in the isthmus Taravao. The bird was rare at that time, and only he was in the isthmus and the mountains Tahiti-iti. Marolles saw only four or five individuals in total, and the locals told him that the parrots lived in large trees on inaccessible escarpments and deep valleys. It is not known nothing about it.
Reproduction:
No data
Food:
No data
Distribution:
The Black-fronted Parakeet they were from tahiti, on french polynesia. Three known specimens collected (two of which are now in Liverpool and one in Tring) collected on the trip Cook in 1773, a fourth collected by Amadis in 1842, now in Perpignan and a fifth collected by the Marolles in 1844, now in Paris(Voisin et al. 1995).
No specimen has been recorded since 1844.
Conservation:
โข Current category of the Red List of the UICN: Extinct.
โข Population trend: Extinct.
โข Population size : There is no individual left.
Rationale for the Red List category
The frentinegro Perico were known tahiti, (french polynesia), but it has not been seen since 1844 and it is now regarded as a kindextinct. Possible causes include deforestation, the hunting and predation introduced species.
Hume y Walters suggest that because the Tahitians highly prized the green and red parrot feathers brought from Tonga, it is possible that excessive hunting in the past has been, at least in part, responsible for the disappearance of Black-fronted Parakeet.

โท The world of Pets: Dogs, cats, birds, reptiles, amphibians
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.

Appreciated a decrease of the species due to deforestation at the local level (in particular in Colombia).
The population size World has not been quantified, but this species is described as ยซrareยป (Stotz et to the. 1996).
The population is suspected to be stable in the absence of evidence of any reduction or substantial threats.
"Blue-fronted Parrotlet" in captivity:
These birds are rare to see them in captivity. Any person possessing one has to know that it can not be put into freedom, It must be part of a well-managed maintenance program to ensure the continued existence of this species.
It lives in humid forest, of gallery and sheets, up to 1700m.
It can also be seen sporadically in coastal areas, possibly in response to food availability.
Reproduction Blue cheeked Parrot:

In the wild, the breeding season occurs in March in Guyana. In captivity, the female lays 3 eggs that we do not know exactly the incubation period.
Food Blue cheeked Parrot:
We don't know the details of your menu, but it is assumed that they eat almost exclusively seeds, and berries.
Distribution Blue cheeked Parrot:
The Amazona dufresniana It is located in southeast Venezuela (Bolรญvar, with a record isolated on Amazon), Northern Guyana (north of 5ยฐN), Northeast Suriname and French Guiana northeast (Y way Collar 1991).
There are reports of Para and Amapa, Brazil, where its occurrence seems likely, but there is no conclusive records (Y way Collar 1991, Collar 1995). The scarcity of records from frequently surveyed areas suggests that it is a low-density and rare species., at the least in parts of its range (Y way Collar 1991).
