Justification of trend
It is suspected that the population is increasing as habitat degradation is creating new areas of suitable habitat.
"Spectacled Parrotlet" in captivity:
In captivity is common in some European countries, rare elsewhere. It is a bird lively, Intelligent and with attitude. They are highly valued for being quiet; they can learn many words and whistle very well. Son loving and they love spending time with their owners, However, they are happy and independent enough to happily play with their toys while the owner is absent. Need much space as it is a bird very active, as well as different toys.

The female It has a yellow stain on the cheek more defined and larger than the male, Bello to singr pale gray (Pink in males)
The juveniles has plumage duller overall.
The bill top of immature male black obscures two years old, While the lower peak black four years.
(Gould, 1838) – Smaller size, tail shorter dark mottled.
Habitat:
Variety of types habitats, including forests of eucalyptus, heaths, subalpine areas, pine plantations and occasionally in urban areas.
They are often seen flying in pairs or trios formed by a pair and their young., although outside the breeding season they can join in more numerous flocks.
Reproduction:
have a long breeding season, that varies throughout its range, although Tasmania in general it is from October to February. Both sexes construct the nest in holes of mature trees, high, generally eucalyptus. Fill the hole of wood chips. The same tree can be used for many years.
One or two eggs form a clutch. Only the female incubates the eggs, While the male supplies the food. Both parents help rear the chicks, Although usually only one chick survives. The chicks leave the nest about three months after hatching and remain in the company of their parents until the next breeding season.
Food:
Seeds native trees, terrestrial plants and pine cones. Some insects also part of their diet. Unlike other cockatoos, a significant proportion of the diet up wood borers worms. The bird put his ear against the surface of dead trees to hear the sound of worms. If a worm is detected, the bird will use their powerful beaks to pull pieces of the tree until you get to the meal, often leaving a pile of wood chips at the base of the tree. These scars on dead trees are a common sight in the forests of Tasmania.
Distribution:
Size of its range (breeding/resident ): 2.700.000 km2
It is up to the 2000 meters throughout Southeast Australia, from South Eyre Peninsula to the east-central Queensland.
Your number is declining in parts of its range due to habitat fragmentation and loss of large trees used for breeding.
In Tasmania is common and nomadic. They can be seen in many parts of the state and in the larger islands Bass Strait.
• Current category of the Red List of the UICN: Least concern.
• Population trend: Stable.
This species has a very large range, and therefore not approaching the threshold of vulnerable. Not threatened worldwide. CITES II. As with most other cockatoos, its long-term existence depends on the continued availability of hollow trees for nesting,
The population is estimated at at least 25.000 birds.
The population trend appears to be stable.

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.

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 ⓘ
Near Threatened ⓘ(UICN)ⓘ
• Current IUCN Red List category: Near-threatened.
• 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.

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.

The bill black; bare orbital skin yellowish white; irises yellow-orange; legs grey.
Both sexes similar.
Immature with the bill color horn, greyish the bare orbital skin, and no Scarlet feathers behind the eye or red in the region where bend the wings.
The Thick-billed Parrot is often treated as the same species as the Maroon-fronted Parrot.
It inhabits in Highlands with mature pine forests or pine forests with other conifers of the genus Pseudotsuga, malls Populus and/or trees of the genus Quercus, in areas isolated and often rugged, sometimes are also observed in towns of lowlands.
They are mostly distributed at altitudes between 1,500 and 3,000 m, breeding generally at heights between 2,000 and 3,000 m.
Its preference they are areas with Pinus arizonica and Pinus ayacahuite. In general, observed in flocks. They rest in large groups on inaccessible cliffs or trees with dense foliage. Diurnal movements of up 40 km between resting areas and feeding.
Long-lived and gregarious, they form social groups; because of this, over time the Thick-billed Parrot they return to visit forests which are of your choice.
Reproduction:
Nest in the cavities of trees, usually pine, but also, according to sources, in trees of the species Populus tremuloides and Pseudotsuga taxifolia; usually in trees partially dead or alive, with small holes excavated, for example, by woodpeckers as the Northern Flicker (Colaptes auratus) or caused by fungal decomposition in the Heartwood wood; sometimes very together (in the same tree) When there is available room, Although generally scattered.
The breeding season coincides with the ripening of the pine seeds; birds, usually, They arrive at the breeding area between the months of April and May, carrying out the mid June to end of July update. The young begin to leave the nest from early September to late October, after 59 – 65 days, depending on their parents for a period of time after fledging.
Clutch of 2 to 4 eggs, generally three, Perhaps variable with the size of the harvest of pine seeds. The care of the eggs during incubation is carried out by the female and the care of the young is biparental..
Food:
Diet Thick-billed Parrot It is mainly composed of pine seeds (including the of the Pinus teocote and of the Pinus leiophylla) extracted from the cones with its powerful beak; They also feed, according to sources, of seeds and sprouts coniferous Pseudotsuga, fruits of the American black cherry (Prunus serotina) and acorns.
Distribution:
Size of the area of distribution (reproduction / resident): 67.100 km2
The distribution Master of the Thick-billed Parrot lies between the West and centre of Mexico, with sporadic movements towards the North and towards South.
Like other bird specialists in pine seeds, the Thick-billed Parrot wanders widely after playback, sporadically to South-West of Mexico in Jalisco, Colima and Michoacán, previously to the East up to Veracruz (Although these records are possibly involved the Maroon-fronted Parrot – Rhynchopsitta in terris) and, possibly, Coahuila de Zaragoza.
Formerly it was a sporadic visitor, and possibly resided and lesson in Arizona (especially in the mountains of Chiricahua, in the South) and in New Mexico, EE.UU, Although since the beginning of the century 20 no large-scale visits have been observed and the latest reproductive data in the area date from the 1938.
The presence of the Thick-billed Parrot is determined by the availability of pine seeds; the core of your playback area It seems to be the most constantly occupied area.
The decrease important in your population during the century 20 as a result ,mainly, of the loss and degradation of habitat, with the absence of these birds where the large pines were cut down, mainly by forestry. The loss of birds in EE.UU. was attributable to the hunt, but his presence there, probably, It was only in the short term, When were feeding conditions unusually favorable (or on the contrary very unfavorable in Mexico).
The recent threats in Mexico they are the trade in live birds and the continuous loss of habitat for livestock, as well as logging (the loss of old trees for nesting is a major problem that puts this species at a higher risk than the of the Maroon-fronted Parrot, when the latter uses the cliffs to build their nests).
Confiscated and captive-bred birds were released in Arizona at the end of the Decade of 1960, with the first successful reproduction in EE.UU. shortly after, although unfortunately the birds have mostly disappeared from that area.
• Red List category of the UICN current: In danger of extinction
• Population trend: Decreasing
The thick-billed Parrot is found in danger of extinction due to the destruction of nesting habitat, as well as his commercial exploitation, the decrease of population who have suffered these parrots is very evident to those that, long overdue, They inhabit the timber areas of Chihuahua and Durango (Lanning and Shiflett, 1981).
The commercial logging of pine living for wood, as well as standing dead trees to obtain their pulp, they are ending with a lot of nesting sites effective and potential for these birds (Lanning and Shiflett, 1983).
The trade of the parrots seemed to be minimal until the 1980s (Lanning and Shiflett, 1981), However, It is estimated that during 1985 and 1986 between several hundred and even thousands of parrots were illegally trafficked to the United States of America (Snyder & Wallace, 1988).
To reduce these threats the species and its habitat, There are legal instruments such as the vedas and provisions in the Law-General ecological balance and environmental protection (LGEEPA) and General wildlife law (LGVS); as well as the Norma Oficial Mexicana NOM-059-SEMARNAT-2001 that lists the species of Mexican wild flora and fauna under some risk category and the inclusion and modification mechanisms.
The size of the population of the Thick-billed Parrot It is estimated between 2000-2800 mature individuals.

Description:
17,5 cm.. length.
The Red-fronted Parrotlet(Touit costaricensis) has the forecrown, anteriorly of crown, lores and stripe under the eyes, red; sides neck, cheeks and upperparts, green with the back of the crown and nape slightly paler and yellower. Inner wing-coverts green; exterior and median coverts and wing leading edge, red; primary coverts black.
Primaries and outer secondaries, black with green margin to outerweb of the primaries. Inner underwing-coverts, yellow, the outer, red. Feathers on base of the beak, on chin and throat, brighter yellowish green; the chest, the belly and undertail-coverts, green tinted yellowish. The tail greenish yellow with a black tip (except the outermost feathers) and dark green subterminally. Bill pale yellow; cere and bare periophthalmic, grey; irises grey; legs slaty.
The female It has less red on the upperwing-coverts, and perhaps more yellow in the underwing-coverts; probably, on average, are smaller than males. The immature It has little or no red on the head.
The Red-fronted Parrotlet It has sometimes been treated as conspecific with the Blue-fronted Parrotlet(Touit dilectissimus) North of South America and Panama. Although these taxa are clearly allied and share a recent common ancestor, most authors now treat them as separate on the basis of their clear and consistent plumage differences. The structural divergence can also exist in the Red-fronted Parrotlet longer seems to show the uppertail-coverts (extending almost to the end of the tail) its counterpart Southern, While (although the sample is small) it suggests a sexual dimorphism by the length of the wings and tail on Red-fronted Parrotlet but not in Blue-fronted Parrotlet.
Habitat:
Generally observed in the canopy moist forests at mid-altitudes. It moves towards the thicket, on forest edges, flying over the clear, sometimes in the lowlands (sometimes at sea level, especially in southeast Costa Rica), where perhaps it is a seasonal visitor. Tolerates some habitat alterations.
Observed in association with Red-headed Barbet(Eubucco bourcierii) and Blue-and-gold Tanager(Bangsia arcaei), both species associated in cool wet forests in the upper tropics and subtropics.
Observed to 3.000 meters in Costa Rica in the early dry season and reported regularly at altitudes 500-1.000 m during the wet season. Usually in pairs or small flocks family.
Reproduction:
The family size usually between 4-5 birds, suggests the clutch usual 2-3 eggs. probably plays during the season, dry.
Food:
They feed on fruits trees and epiphytes, such as Cavendishia and Clusia, but probably also include flowers and seeds.
Distribution:
Size of its range (breeding/resident): 10.000 km2
The few records Red-fronted Parrotlet existing in Costa Rica come, mainly, the highlands of central-south Caribbean side, where its range seems to extend to the south, from Monteverde, Turrialba volcano and Lemon.
Although there are no records in much of the east of Costa Rica, its existence can be continuous along the Cordillera de Talamanca (perhaps only in the Caribbean side) to western Panama. The handful of panamanian specimens and records from observations, They are mainly from the western highlands to a report from the east, about the Cocle Province.
It is obviously a kind rare and presumably in decline due to continued deforestation (at least in the lowlands) in a limited range.
Conservation:
• Current category of the Red List of the UICN: Vulnerable.
• Population trend: Decreasing.
Population size : 2500-9999 specimens.
Rationale for the Red List category
This species is classified as Vulnerable because the clearing and forest fragmentation at middle elevations, mainly in the Central Volcanic Range and in the Sierra de Tilarán of Costa Rica, It is likely to be causing significant slopes in its small range and (presumably) in population.
Justification of the population
It is estimated that the breeding population of the Important Bird Areas of Costa Rica is 1.000 to 4.000 mature individuals (J. And others Craido 2007, J. Sánchez et al., In 2007), so it is believed that the total population may be within the range of 2.500-9.999 mature individuals. This is equivalent to 3.750-14.999 individuals in total, rounded here to 3.500-15.000 individuals.
Justification of trend
It is suspected that the population species is decreasing at a moderate rate, in line with continued clearing of its forest habitat in the northern part of its range.
Conservation Actions Underway
CITES Appendix II. Live in several areas protected, including national parks Braulio Carrillo, Tapantí-Cerro de la Muerte and Monteverde, Costa Rica, and La Amistad International Park and adjacent reserves in both countries. But, The legal protection of Palo Seco Protected Forest (BPPS) (a booking Panama adjacent to La Amistad) has not prevented clearance for agriculture (Angehr and Jordan, 1998).
Conservation Actions Proposed
Evaluate the importance of habitat outside the breeding season (J. Created en lit. 2007, J. Sanchez et al., In 2007). Conduct surveys to determine the total size of the population. Study of the ecology of the species (J. Sanchez et al., in bed. , 2007). Monitor population trends through regular surveys. Monitor rates of loss and recovery of forests (J. Sanchez et al., In 2007). Effectively protect the Bosque Protector Palo Seco (BPPS).

Minor Concern ⓘ(UICN)ⓘ
• Current category of the Red List of the UICN: Least concern.
• Population trend: Decreasing.
• Population size : Unknown.
Justification of the Red List of the Category
This species has a very large range, and therefore does not approach the thresholds for vulnerable under the range size criterion (extent of occurrence <20.000 km2 combinan con un tamaño gama disminución o fluctuante, hábitat medida / calidad, o de la población tamaño y un pequeño número de localidades o fragmentación severa). A pesar de que la tendencia de la población parece estar disminuyendo, el descenso no se cree que es suficientemente rápido como para acercarse a los umbrales para Vulnerables según el criterio tendencia de la población (> 30% decrease of more than ten years or three generations). The population size It has not been quantified, but is not believed to be a reason to approach the thresholds for Vulnerable based on population size criteria (<10.000 individuos maduros con una disminución continua estima en> 10% in ten years or three generations, or a specific population structure). For these reasons, the species is evaluated as Least concern.
Justification of the population
Recent world population is unknown given taxonomic divisions.
Justification trend
This species is suspected that there may be lost 7,0-7,3% of habitat within its distribution over three generations (18 years) based on a model of deforestation of the Amazon(Soares-Filho et to the. 2006, Bird et to the. 2011). Given the susceptibility of this species to hunting and / or entrapment, it is suspected that its population can decrease <25% en tres generaciones.
"Red-crowned Parakeet" in captivity:
little presence in captivity and found only in some aviaries, where however they reproduce very well. After acclimation is a strong bird that can live outdoors. It is a bird suspicious although curious and playful nature, especially if they feel safe. Young birds in captivity quickly lose their fear and are very attached to their caregivers. It´s noisy, especially in the morning and sleeps in the nest. The female is very aggressive during the breeding period with other birds..

According to the IUCN categories it is considered as Vulnerable (VU). Habitat degradation and trade are adversely affecting the population.
The ban on the capture and trade has improved the status of this species. The rate of decline was very rapid in the Decade of 1980, Although at present has been reduced and even stabilized. But, the population is still very small, with records in very few places, and as a result, according to the IUCN categories, qualified as vulnerable.
"Yellow-faced Parrotlet" in captivity
Captured for the trade of wild birds, It is estimated that 17.000 birds were captured between 1981 and 1994. The rate of mortality during capture is estimated between the 40% and the 100%. Rare and unknown in captivity until 1979-1980.

The Short-billed black cockatoo(Zanda latirostris) It is a large black cockatoo..
It has great bill black, crest erectile, white spot in the area ear and white panels on the tail. The female It is similar except patch area ear large and slightly yellowish white.
The immature Similar to adult female.
Closely related to Baudin's black cockatoo(Zanda baudinii). They were formerly treated as a single species.
Mainly inhabits in native forests eucalyptus and shrubland or heathland. Visit temporarily plantations exotic pines.
Sometimes you see them in cities or at the edges of roads. It is also a visible visitor to the gardens containing native plants with hard fruits around Perth.
Usually they see them in groups of three or in small flocks, but occasionally gather in large flocks composed of hundreds or, exceptionally, thousands of birds. Sometimes it is associated with Baudin's black cockatoo(Zanda baudinii) wave Red-tailed black cockatoo(Zanda Banksia) in places where food is plentiful.
The species is said to be Residents in areas of high rainfall They are retaining much native vegetation and are emigrants of the driest regions and places where most of the native vegetation has been removed.
Reproduction:
They do not breed until they are at least four years old..
Adult birds They mate for life, and stay together throughout the year.
Reproduction occurs mainly in the region Wheatbelt, northwest of the Stirling Range about Three Springs, but it has also recorded on the coastal plain in the South West, about Bunbury.
The reproductive activity It is limited to eucalyptus forests. They make their nests in large holes in the top of the eucalyptus.
The eggs They are white or cream, and they have no marks. Son incubated by female only, for a period of 28 to 29 days. The nestlings are fed by both parents, Although during the first 10 to 14 days after hatching they are fed exclusively by the female.
Adults return to the same breeding area each year.
Food:
It feeds mainly from seeds and occasionally nectar, fruit and insect larvae.
Distribution:
Size of the area of distribution (reproduction / resident): 196.000 km2
Endemic southwest Australia.
Conservation:

Endangered ⓘ(UICN)ⓘ
• Current category of the Red List of the UICN: In danger of extinction.
• Population trend: Decreasing.
On the basis of the distribution of birds during the breeding season, the total population of the Short-billed black cockatoo it has been estimated that is between the 11 000 and 60 000 birds, although there are those who affirm that its population could count on less than 10 000 birds.
The decline of this species It is mainly due to the loss and fragmentation of habitat. This has been caused by the clearing of native vegetation, mainly for agricultural purposes, Since the mid-20th century.
No specific information available on future changes in population size. But, the range of the species is thought to continue to contract for some time, which leads to a concomitant decrease in population size.
"Short-billed black cockatoo" in captivity:
A program captive breeding It was established in 1996 by the Department of Conservation and Land Management (CALM), in association with poultry farmers and licensed Zoo of Perth.
The genetic diversity of the captive population is enhanced by an 'abandoned' program’ that rehabilitates injured birds in the wild and then incorporates them into captive breeding.
Some eggs and chicks are caught illegally for sale in the markets of poultry. Although the demand for the species is said to have declined over the past decade, high market prices (approximately 3.000 dollars per bird and 5,000 $ couple) together with the scarce success of breeding captive birds, They suggest that Illegal take of this cockatoo will continue to be a continuing threat to the survival of this species..
