In Timor the species is found in forests, acacia savannas, primary and secondary forest, from sea level to the 2.200 m (2.600 meters altitude extreme). In Wetar, observed in 1990 in recently logged forests, near the coast.
The ecology of the species is probably similar to that of the Red-winged Parrot, but it is not well known; observations of birds that fly involve couples and small flocks. A couple allowed a closer approach, observing her in silence to three meters high in a big tree.
Reproduction:
Their reproductive habits are unknown, probably similar to the of the Red-winged Parrot.
Food:
Probably similar to the of the Red-winged Parrot: seeds, fruit, flowers and insects; in the mangroves, the mistletoe is your favorite food.
Distribution:
Size of the area of distribution (reproduction / resident): 28.500 km2
The world population is estimated at around 10.000 specimens and it is probably stable, although like most Indonesian parrots the species is vulnerable to capture and habitat loss. A moderate number in captivity.
The total population has been estimated at 10,000 individuals (Lambert et to the., 1993), probably including mature individuals 6,700.
The population is suspected that it may be declining due to the continuous destruction of the habitat and unsustainable levels of exploitation.
Ongoing conservation actions
Appendix II of CITES. Quotas were imposed during the Decade zero of 1990 while uncertainty existed about the total population size, but these are not met.
Conservation Actions Proposed
• Review estimates of the population of the species and review the impact of trade on their numbers..
• Determine if declines are still evident.
• Protect areas of suitable habitat.
"Olive-shouldered Parrot" in captivity:
Game, with low noise level, aggressive with other birds. You can require deworming.
The Orange-bellied Parrot(Neophema chrysogaster) is a small ‘Grass parakeet‘, so called for spending a lot of time on the ground feeding on seeds and grasses.
adults have, approximately, 21 cm length and a weight of around of 45 to 50 g..
Has the crown, the nape and the the mantle bright green, with one frontal band dark blue and a lighter blue later point that does not extend beyond the eyes.
Face and lores are yellowish-green. You have a few different bands in the wings Green and blue colors, the vane inmates of the wing-coverts are green, the blue outer.
The primary coverts are dark blue. The primary feathers Black has the outside edges with fine violet blue and yellow. The secondaries has a green border.
The underparts is blue. The chest Green is mixed with the greenish yellow color under the tail. The belly is very stained Orange. The top of queue is green with blue tip. The lateral tail feathers they are yellow with blue-green bases.
Peak and iris are black, the legs are grey.
The female is more off than the male, the frontal band has a single tone. The stain ventral Orange is smaller.
Between the juveniles, the frontal band is barely visible. The Wing band is very prominent and the bill is pale.
As one migratory species, its habitat varies throughout the year, with the birds that live in the marshes, coastal dunes, pastures, scrub, estuaries, Islands, beaches and Moors generally within the 10 km of distance from shore.
There is practically no records more towards the inside of 5 km and most are within 2 km from the coast. The holes of mature eucalyptus, as the Smithton Peppermint (Eucalyptus nitida) and the Swamp gum (Eucalyptus ovata), they are used by the Orange-bellied Parrot for the nesting during the breeding season in Tasmania, and breeding habitat is a mosaic of moorland and reed-covered land, dominated by the Button Gras (Gymnoschoenus sphaerocephalus) and forests.
The behavior of foraging species are usually characterized by the power in the suelor or in low vegetation, in general a less than 1 m above ground.
The birds they feed usually in pairs or individually during the breeding season, and in small herds of variable size in non-breeding season. Solitary birds often have been feeding with other species, especially with the Blue-winged Parrot (Neophema chrysostoma).
Reproduction:
In Tasmania, the only breeding place, spawning takes place in the months of November and December.
The nest of the Orange-bellied Parrot is located in natural cavities, between the 8 and 25 meters of height in eucalyptus (Eucalyptus nitida) and less frequently, in the (Eucalyptus ovata). The nest is sometimes maintained during several consecutive years. The marital ties they are strong and sometimes last a lifetime.
The spawning included among 3 and 6 eggs they are incubated during 21 days. Young people are altricial and remain in the nest for at least 5 weeks.
Food:
Initially, on Spring, the Orange-bellied Parrot they feed on plants. They mostly eat seed Sedge (Reedy) and parts of the herbs of the genus Boronia or Actinotus.
At the beginning of Winter, the regime being vegetarian, suffering some transformations. the Orange-bellied Parrot consume algae in decomposition, seeds and herbs Poaceae and Halophyte, that is to say, you adapt to saline environments, as the Rock Samphire (A maritime rhythm).
The goosefoot )Chenopodium) and Salt plants (Atriplex) also classic in their food. Introduced plants such as the Sea rocket (Cakile maritima) they are also popular.
Distribution:
Tamaño del área de distribución (reproducción/residente) 3.100 km2
They migrate across Islands in the West of the bass strait (mainly King Island) towards the coast South of Australia, to Hibernate from the months of March to July, mainly along the coasts of the Bahía Port Phillip, Victoria (largest number of birds in Point Wilson and Swan Island, including the Queenscliffe Golf Course). They also overwinter in small numbers., from Gippsland, Victoria, to the West of the Coorong, Southern Australia. Occasionally occur during winter in areas of Tasmania and surrounding islands, as well as other individuals spend the summer on the mainland.
Every summer around 40 couples are reproduced, and an analysis of nine nests showed an average offspring of 1,7 pups per pair. The post-breeding population increased by about 50 individuals, of around 170 birds, but the population is becoming increasingly smaller, which suggests a high annual mortality. Adults begin to leave the breeding area in February and fly across the coast of Tasmania, crossing the bass strait, mainly through King Island (also records in the Hunter Croup) towards the coast of the Southeast of Australia (young birds usually travel a month later).
The Orange-bellied Parrot They tend to move around the continent, and are in the South of Australia at the end of winter. They return to breed in the months of September and October, they usually travel directly back to their breeding grounds. Since 1979 to 1990, the wintering population has remained relatively stable, with a count of 67 to 126 individuals registered every year (with a maximum of 50% of the world's population known with presence in Point Wilson).
In the last century the species flying in flocks of thousands of individuals (and raised as far East as Sydney up to approximately 1907). Wintering habitat loss and capture for the bird trade are cited as factors in its decline.
Possible winter habitat loss remains a threat, as does competition from introduced herbivores, the disturbance, and the possibility of exploration and exploitation of minerals. A detailed recovery plan includes the management of winter habitat with the exclusion of grazing animals, the diversion of economic activity and the development of Murtcaim Wildlife Management Area about Point Wilson. Captive-bred birds have been released and mixed with wild individuals.
Conservation:
• Current category of the Red List of the UICN: Critically Endangered
• Population Trend: Decreasing
The Orange-bellied Parrot It has a very low population size. This very low population size is even more significant, given that the species migrates through of the Bass Strait, with which this species is subjected to the additional risk by stormy phenomena on their migratory journey.
Has a restricted geographic range when breeding, and apparently a limited supply of food during migration and winter.
The species is found in a single population of between 100 and 150 mature individuals. Habitat loss, fragmentation and modification, particularly on the migration route and in the wintering areas, they are the key threats to the survival of the species.
For a small population, stochastic factors, as the disease, storms during the migratory species, and the destruction of nests by forest fires have the potential to reduce the survival of the species in the long term.
The Orange-bellied Parrot It has a restricted geographical distribution which is precarious for its survival.
The Scientific Committee of Threatened Species considers that the Orange-bellied Parrot has suffered a historic decline since European colonization. It is considered, In addition, that the recent recovery actions that have been implemented are having a beneficial impact on the species and the possibility of future stability in the reproduction sites is becoming apparent. But, as the population of the Orange-bellied Parrot is so low, the data that we have are based on a small area of occupancy and it is likely that this species continue suffering from a series of threats in course, with what the Committee may not be sufficiently secure that available information indicate that the population is stable and safe.
Future declines in population are still likely as a result of potential threats, especially the stochastic and genetic threats to small populations are likely and that can lead to the extinction.
"Orange-bellied Parrot" in captivity:
The Orange-bellied Parrot is very rare in captivity and is, probably, more present in the hands of European collections. There are also some captive birds by some fans in Australia, to the South of the continent.
Fifteen years ago in South Australia, under expert supervision, were built cages with the aim of raising these birds and avoid that the Orange-bellied Parrot disappeared completely. In the early years, most of the young people died from diseases of the beak and feathers (PBFD), a viral disease (virus BFD). Similarly, cold winters in this region, where was launched the project, they had a negative effect on the end result.
Once the aviaries were displaced to areas more temperate and increased its amount, the result is improved and each year dozens of parrots have been released into the wild.
The Orange-bellied Parrot they are birds calm, peaceful and little noisy. They belong to the less active within the genre of the kind Neophema, so tend to the Obesity. These birds spend much time ashore. Usually, bathe once a day, in long baths. Reproduce well in captivity. They are exceptionally susceptible to various infections, including the intestinal parasites. These birds also, often, they die without apparent reason.

Mantle brown, but more to the tail; scapulars dark green-edged Brown; rump and uppertail-coverts bright green. Upper, the wing-coverts green, sometimes with a small yellow spot on the curve of the wing
folded; wing feathers yellow. Primaries brown with vane Blue-Green external; the secondaries brown.
The feathers in the upper area of the chest brown with a narrow green edge at the bottom; the rest of the underparts green, but darker bases of the feathers, giving a mottled look.
Tail dark brown with green washing and dark green tip.
The upper jaw and cere grey-black (darker towards tip), lower pale, almost white; irises yellow-green light; periophthalmic ring and legs dark grey to black.
Both sexes similar.
Immature generally more muted than adults and with the irises brown.
Poicephalus cryptoxanthus cryptoxanthus (Peters,W, 1854) – Nominal species
Poicephalus cryptoxanthus tanganyikae (Bowen, 1930) – As the nominal but more pale species; more green and less Brown. Green mantle and underparts brighter. Bib of brown feathers on the throat and upper of the much smaller chest than in the nominal species; the head more color olive brown.
Habitat:
Is located in almost all the forests: riparian forests, in the interior of the savannah forests and in the dry forests of southeastern Africa, but it seems to avoid the miombo woodland and prefers areas with baobabs.
Registered in coconut plantations, riparian forest, the edges of small farms and mangroves.
Confined in lowlands (below the 1.200 metres above sea level in Tanzania and 1.000 metres in Malawi).
Gregarious; usually seen them is in small flocks of about 12 birds, but can meet up to 50 in places of power. Sometimes it is associated with the Cape Parrot and also observed feeding in the company of the Madagascar Green-Pigeon.
Reproduction:
Normally nest in hollows of old trees of woodpeckers, between 4 and 10 meters above the ground. Often has to compete with the Cape Parrot, Meyer's Parrot, squirrels and Crowned Hornbill the nesting sites.
Season of laying egg is April-May in the South of its range.
The laying is of 2 to 4 eggs, which are incubated solely by the female during 26-30 days, While the male feeds her on the nest.
The chicks they remain in the nest during 50-54 days Before leaving for the "breeding area", which is usually an area of dense broadleaf trees with a nearby water supply. During this time the chicks are silent and largely immobile, becoming fully independent a few 28 days later.
They forage, with slow and deliberate movements, climbing and often holding the food between the claws. They drink daily, around midday.
Distribution:
The Brown-headed Parrot are distributed by the southeast of Africa. From the North-East of South Africa (Swaziland, Zululand and Transvaal) through the southeast of Zimbabwe, Mozambique and South of Malawi to the East of Tanzania (including the island of Pemba and southern end of Zanzibar) and southeastern edge of Kenya.
Apparently sedentary. In some places, the Brown-headed Parrot, are a species common, especially close to the coast and in the South of its range, but in some other areas are scarce or rather local; in Zanzibar possibly extinct.
Distribution Subspecies:
Poicephalus cryptoxanthus cryptoxanthus (Peters,W, 1854) – Nominal species
Poicephalus cryptoxanthus tanganyikae (Bowen, 1930) – Mozambique, to the North of the Save River across the South of Malawi and this from Tanzania to the coastal part of Kenya.
It is not threatened, although its distribution has contracted since 1990, to a large extent due to the capture illegal for the industry of cage birds.
More and more vulnerable due to the loss and fragmentation of their habitat.
Largely confined to protected areas in Zululand and East of Transvaal.
"Brown-headed Parrot" in captivity:
The only data we have on this bird, according to sources, is that one specimen was still alive after 32,1 years in captivity.

The Nicobar Parakeet(Psittacula caniceps) has the crown, upper cheeks and ear-coverts pale grey; stripe black in the region perioftalmica through the lores up to the forecrown; the lower cheeks and the chin are black. Nape and upper mantle pale gray bathed in blue; rest of the upper region green grass pale.
Upperwing-coverts green; primaries and secondaries Green with dark tips. Underwing-coverts green. Underparts green, slightly paler than upper parts. The elongated feathers central tail green with grey tinge, outer green.
upper jaw coral red, the lower black; cere dark grey; irises orange-red; legs dark gray.
The female has the bill black, the grey of the head and nape more strongly impregnated with blue, and tail slightly shorter.
The immature similar to females.
Habitat:
The Nicobar Parakeet it is difficult to locate visually among the dense foliage, Although its presence is revealed by their distinctive calls. Their flight is fast and direct.
They inhabit in the high rainforest. Generally held among the dense foliage on canopy, about everything when not fully.
They are perhaps most abundant in the coastal forests than inside.
Has also been recorded in areas with plants of Areca catechu and coconut plantations, which suggests a considerable tolerance of the species in habitats modified.
Usually, observed in pairs or in small groups.
Reproduction:
Unknown breeding habits.
Food:
Unknown diet except for the fruits of Pandanus, abundant in the inhabited islands of the Nicobar archipelago.
Distribution:
Size of the area of distribution (reproduction / resident): 1,100 km2
endemic to the Nicobar Islands, located in the Indian Ocean and belonging to the India. Registered since Great Nicobar, Montschall and Kondul. Resident. His status is unknown but they are potentially at risk due to habitat loss due to the expansion of rice cultivation; also affected its population because of the bird trade, Although there is little local use of these birds as pets and there are no known international traffic.
The population of the Nicobar Parakeet It is suspected that It may be waning as a result of the destruction of habitat due to the tsunami of the 2004 (K. Sivakumar in litt. 2007), due to the development of the island, and because the capture for the wild bird trade. But, more research is needed to establish with precision the trends.
Probably between 10,000 – 15,000 specimens on freedom.
The main threats to the Nicobar Parakeet They come because of the large number of birds that are trapped for the cage bird trade.. On the other hand, the increase of settlements on the Islands It has led to increased pressure on natural resources and the planned development projects may seriously affect the habitat of this species. The tsunami of 2004 It destroyed large tracts of coastal forest that may have caused a further decline in the population. But, the data remains scarce, and the rate of regeneration of these forests is unknown (K. Sivakumar in litt., 2007).
Conservation Actions Proposed:
– Determine the impact of the trade in the species.
– Calculate the rates of forest loss.
– Protect remaining habitat areas.
– Assess the impact of the tsunami of 2004.
"Nicobar Parakeet" in captivity:
There is not much information available; probably brought for the London Zoo at the beginning of 20th century; kept as pets, at an unknown number, by the local population of the Nicobar Islands
Since the Nicobar Parakeet is a species so rare, It is not recommended to keep them captive, it is preferable to place them in a breeding program well managed by expert hands.
Alternative names:
– Nicobar Parakeet, Blyth’s Parakeet (English).
– Perruche des Nicobar, Perruche de Blyth (French).

The Green Parakeet(Psittacara holochlorus) is a medium-sized Parrot with the wings in sharp form and the tail long and stitch. Its plumage is bright green, and can present several pens red or orange in the neck. In general, the underwing-coverts are metallic greenish-yellow color, While the the flight feathers and the bottom sides of the the tail feathers are yellow-olive. Presents a eye ring pale beige and the irises orange, the legs yellowish brown.
The Green Parakeet, as well as their subspecies, avoid moist lowland forests; Instead, prefer deciduous forests and gallery forests, scrub, clear and the edges of the forest.
In East Mexico, mainly seen in upland forest with some movements toward deciduous forests at elevations lower than during the non-breeding season. Registered to 2.100 meters in Mexico (the subspecies «brewsteri» at altitudes between 1,250 and 2,000m).
Views in flocks outside the breeding season, sometimes in groups of more of 100 birds, being larger groupings in places where food is abundant.
Reproduction:
The nests of the Green Parakeet they are located in tree cavities (for example, cavities made by woodpeckers), crack in rocks, holes in buildings or termite mounds. Colonial nesting reported in caves in the East of Mexico.
The breeding season has been recorded in the month of January to the East of Mexico (young in the nest); in April in Tamaulipas, to the South of Mexico.
The clutch most common consists of four eggs.
Food:
Diet Green Parakeet is based on seeds, nuts, berries and fruits; reported foods include the fruits of Myrica mexicana, seeds of Mimosa and corn (they can be destructive with their crops).
Distribution:
Size of the area of distribution (reproduction / resident): 275.000 km2
Some specimens settled in cities in southeastern Texas; It is not clear if they come from Pet escapes or are wild vagrant who emigrated from the North of Mexico. It is generally not migratory, but you can scroll to get food.
Subspecies distribution:
Psittacara holochlorus brewsteri
(Nelson, 1928) – Mountains of Northwest of Mexico, to the South of Sonora, Northeast of Sinaloa and South of Chihuahua.
• Red List category of the UICN current: Least concern
• Population trend: Decreasing
The population of the Green Parakeet It is suspected that it is between a slow to moderate decline due to the expansion of intensive farming and capture for the wild bird trade (Juniper and Parr 1998).
The State of conservation, globally, regards it as a kind of Least concern because it is abundant and widely distributed. It is considered one endangered species within the Mexican law by its restricted distribution. Nest boxes they have been provided in the South of Texas nest (Brush 2007).
The world population is estimated at 200.000 mature individuals.
Although it is not as popular as other large amazon parrots, the Green Parakeet is maintained as pet by the local population; have also been exported as pets to the United States. Although there are no accumulated figures, during the period of 9 months between October of 1979 and June of 1980, 327 birds were imported to the United States (Roete et to the. 1982).
While the loss of habitat It is probably the factor affecting the population of the Green Parakeet, their capture for the bird trade It is likely to be negative at the local level.
With the signing of the Wild birds Protection Act of 1991, the Green Parakeet can not be imported to the EE.UU. unless they are part of a breeding program authorized.
The marketing of all the species Mexican species parrots (parakeets, parrots and macaws) is banned in Mexico. Since the year 2008 It is a federal crime to catch, sell, buy this type of animal.
"Green Parakeet" in captivity:
Maintained as pet by the locals although its marketing is prohibited in Mexico.
The illegal trade in parrots and macaws is held thanks to demand from consumers. If the demand for these wild species is reduced, then the offer would be reduced and therefore the illegal capture.
According to sources, a specimen lived 21,8 years in captivity

The White-capped Parrot(Pionus seniloides) It is easily identifiable by the "peak" yellow, head usually white, with the crown with reddish speckles, feathers of the nape and sides of the head with dark blue edges and red dyes which gives the appearance of flake.
Breast
with greenish blue edges, under belly and internal base tail red.
Iris of color Brown and legs gray-green.
The youth have crown and chest green, and green spots on the sides of the head and neck.
Note:
Previously he was treated as a subspecies of the species Pionus tumultuosus, that is to say, Pionus tumultuosus seniloides. A midyear 2014 it is considered as own species.
It is a kind Rare. It inhabits in humid jungle and edges, from the 1900 to 3000 m. It is mainly a species of temperate zone, but you can descend to lower elevations.
Like most highland parrots, the White-capped Parrot are rather nomads, widely wandering in search of fruits and seeds (now perhaps more as a result of extensive deforestation). Usually observed in flocks 3-25 birds, sometimes more. More active with grey weather, overcast skies. Difficult to see while feeding or resting in the upper canopy. Its silhouette in flight resembles a Amazona but with the beating of wings deepest.
Reproduction:
It nests in tree hollows.
Food:
Feeds of seeds, fruit of Turpinia paniculata and plants of the family Clusiaceae; sometimes in cornfields, causing damage to their crops.
Distribution:
Size of its range (reproduction / resident): 1.020.000 km2
Live west of Venezuela (from the border Trujillo–Lara) through the East of the Andes of Colombia (rare in the western Andes), and on both sides of the Andes in Ecuador and Northwest of Peru (west to Cajamarca and this, at least until Freedom)
Conservation:
• Current category of the Red List of the UICN: Least concern.

Justification of the population
The size of the world population It has not been quantified, but this species is described as «quite common«, but irregular distribution (Stotz et to the., 1996).
Justification of trend
They suspected that the population is declining due to the continuous habitat destruction.
"White-capped Parrot" in captivity:
Rare in captivity. In Europe they arrived first at the beginning of the century 20 and then the early 70. In captivity, However, They were raised for the first time in the second half of the 80.

The Red-crowned Parrot(Amazona viridigenalis) has the lores, forecrown and crown, bright red, with side margins on the back of the neck and top of the neck, showing blue feathers with black ends; ear-coverts bright green without black ends in feathers; nape boldly festooned with green feathers with their ends in black.
Mantle and back green with some weak black tips; rump and uppertail-coverts, green. Wing coverts green with black margins on some weak feathers. The flight feather, mostly green, the primaries, in general, with dark ends, of dark blue or black, the Outer secondaries, with the ends of blue with red in the outerweb. Under, the wings green. Underparts green, slightly yellowish; some feathers show visible dark tips. The tail is green, in general with its yellow end. Bill pale yellow; irises yellow; legs pale grey.
although females They can have on average less red in the head, probably no consistent sexual dimorphism. The immature She has red in the head very small, with feathers in the central part of the crown green tipped black and subterminally banded pale blue; feathers on the side of the crown, forming broad band over eye.

Habitat:
Video "Red-crowned Parrot"
The habitat of the Red-crowned Parrot son los Bosques deciduous, gallery forests and evergreen floodplain forests in tropical lowlands, with non-breeding birds on dry ridges extend to 1,200 meters in temperate zones Pinus and Quercus.
frequenting cultivated areas where they remain large trees. Usually in flocks, generally larger than its sympatric congeners (Red-lored Amazon and the Yellow-headed Parrot, with which sometimes mixed); in larger flocks in winter. Used roost communally.
Reproduction:
They nest in tree hollows, including abandoned nests Lineated Woodpecker(Dryocopus lineatus), generally 6-20 meters above the ground. Nests reported in trees Taxodium mucronatum, Bumelia laetivirens and Brosimum alicastrum. Reproduction April-May Tamaulipas. The laying is of 3 or 4 eggs. Only the female incubates. The incubation hard 28 days. The young are cared for for nine weeks.
Size of its range (breeding/resident ): 61.900 km2
Northeast Endemic Mexico, where records from southernNuevo León (South of Monterrey) through Tamaulipas (mostly in the center and south of the state) and East of San Luis Potosi, to the North of Veracruz and towards the south until near 21ºN. They can be seen as visitors in the winter Brownsville, southwestern end Texas, USA.
wild populations in California, Florida, Oahu (Hawaiian Islands) and Puerto Ricor (small number in southern dry forests).
Resident but nomadic in winter with some altitudinal movements that lead birds to higher ground in winter (perhaps to exploit the seeds and acorns Pine) and with other movements further away from the breeding range, for example, to the South of Texas. Apparently they return to the breeding area in February, declining along the ridge, but they are most common near the east coast, especially around the Sierra de Tamaulipas and on the slopes east of the Sierra Madre Oriental in Tamaulipas. Otherwise, sparsely distributed and frequently only some strengths as the Valley Sabinas River, Tamaulipas.
Total population estimated in 3.000-6.500. Popular in captivity locally and previously traded in large numbers internationally. Clearly the recent population declines are due to excessive trade and to the continued destruction of habitats scale; they are also you fired in some areas due to crop damage. There are no large protected areas within reach and illegal trade continues.
Conservation:
State of conservation ⓘ
Endangered ⓘ(UICN)ⓘ
• Current category of the Red List of the UICN: In danger of extinction.
• Population trend: Decreasing.
• Population size : 2000-4300.
Rationale for the Red List category
The combination of high levels of exploitation for cage bird trade, loss of habitat and long term estimates reduced density It indicates that this species is declining very quickly. Therefore it qualifies as in danger of extinction.
Justification of the population
In 1992-1994, estimated in an area in Mexico densities indicated a wild population of 3.000 to 6.500 birds (EC Enkerlin-Hoeflich in a bit., 1994). This estimate equals approximately 2.000-4.300 mature individuals.
Justification of trend
The historical densities recorded for the species were 25,2 in the early birds / km2 1970 (Castro 1976), down to 5,7 birds / km2 in an area 1992-1994 (EC Enkerlin-Hoeflich in 1994, Enkerlin-Hoeflich 1995), indicating a population declines of up to 77,4% on a strip of 20 years. It is suspected that the decline will continue at a higher rate to 50% in ten years, due to threats capture and forest clearing.
Threats
• In 1970-1982, 16.490 birds (mainly chicks) They were imported legally to United States.
• Las illegal exports from Mexico and mortality prior to export to the top 50% they are equivalent to 5.000 birds per year (Enkerlin-Hoeflich and Hogan, 1997).
• Los hunters damage nests when removing chicks (sometimes cutting whole trees), reducing the availability of the nest and bringing the permanent abandonment of the site (Snyder et to the., 2000).
• Many gallery forests have been cleared or degraded, with more than 80% lowlands of Tamaulipas cleared for agriculture (especially sorghum) and pastures.
• The habitat of the Red-crowned Parrot It is now distributed unevenly in cattle ranches, where the pressure is greater capture (Enkerlin-Hoeflich and Hogan, 1997).
• The population of Red-crowned Parrot It is distributed in the Biosphere Reserves Heaven and Sierra Gorda (A. G. Navarro in some ., 1998, T. Brush in a bit., 2003), but there are only small colonies in Sierra Gorda and status in Heaven It is unknown (Wege and Long 1995, A. G. Navarro in some 1998).
• Los livestock They are increasingly aware of the benefits of keeping large trees, but this is not reflected in practice.
Conservation Actions Proposed
• Conduct surveys to obtain an estimate of the total size of the population.
• Monitor populations to determine degree of decline.
• Identify the most important nesting aggregations for protection (Enkerlin-Hoeflich and Hogan 1997).
• Integrate ranchers in efforts to reduce capture and regenerate habitat (Enkerlin-Hoeflich and Hogan 1997) .
