The adults of the Red-tailed black cockatoo(Calyptorhynchus banksii) present sexual dimorphism. The male is entirely black, with the exception of the sides of the tail that are of color red glossy. The upper part of the head It is a long Ridge which starts from the front and goes up to the nape. The bill is grey dark.
The females they are slightly smaller. Show a plumage blackish brown with yellow-orange stripes on the tail and the chest. The cheeks and wings they are covered with small yellow spots. The bill is of color bone pale. Lower parts to the tail coverts they are finely excluded in beige.
The youth are similar to the females until they reach the maturity sexual, around the 4 years. Gradually, as they approach this age, YM will acquire their feathers red which gradually replaced their initial feathers in yellow.
Wide variety of habitats. Grasslands and scrub, from the dense rainforests to the forests of acacia and eucalyptus.
Nestbox, These birds are generally dependent on the old eucalyptus, although according to which regions regions, the variety of trees for nesting, could be different.
To feed, flocks of these cockatoos, they penetrate in agricultural lands and orchards, becoming a real plague.
In all parts of the Australian mainland, have been observed seasonal movements.
In the North, most cockatoos flee from high humidity areas during the rainy season.
In other parts of the continent, We are seeing movements directly related to food.
In South Australia, the movements are carried out in the South-North direction and are not necessarily linked to the stations.
Reproduction:
It nests in the hollow of the following trees: MARRI, Jarrah, Wandoo, Karri and Bullich. Eggs are laid on the bottom of a hollow log, up dry branches, between March and December. The cavity can have a depth of one to two meters. The diameter of the entry may vary from 25 to 50 centimeters.
The laying is of an only egg (In rare cases two). The incubation runs by features of the female and lasts between 29 and 31 days.
At birth the chicks are covered by a little and yellow plumage. Most of the time, the second calf is abandoned and eventually dies from lack of food. The surviving offspring is fed by both parents..
Food:
It feeds mainly from seeds, in particular those of Eucalyptus Marri (E. calophylla). Chew small branches, grabs clusters with its legs and โchewsโ them to extract the seeds. Strip the remains to the soil, at the foot of the tree. It is a great vegetarian, also eats berries, fruit, some insects and larvae. Occasionally it feeds on plants or varieties introduced as the radish wild, turnips or melons.
Distribution:
Size of the area of distribution (reproduction / resident): 8.680.000 km2

They are especially prevalent in the northern part of the country. In the South, they are less abundant and more dispersed.
The WPT (World Parrot Trust) contributed funds to a project in the South of Australia for help to save to these birds.
Distribution 5 subspecies
They differ from each other mainly by the size of their beak.
โข Current category of the Red List of the UICN: Least concern.
โข Population trend: Decreasing.
In the past it was common, but now it has become rare, It is distributed unevenly in areas that have been significantly reduced.
The decrease is caused by the deforestation, the competition for the nesting with species native and exotic, as well as the fires.
It is believed that the world's population exceeds the 100.000 individuals.
the subspecies graptogyne was estimated to be in less of 1.000 individuals in 1989.

They are particularly visible in the early hours of the day, When the bands fly over canopy, sometimes very large heights.
They have a direct flight with rapid wing beats. In spite of this, they give the impression of moving slowly, almost in a hesitant way. Its neck tense and the tail feathers widely deployed gives them a vision in flight that is very characteristic. Couples often engage in stunts, with many screams.
(Salvadori, 1876) – Adults of this subspecies differ little from those of the nominal species. But, they differ from the latter by the narrower stripes on the plumage. The bottom of your wings They are green or green with red markings.
Chalcopsitta scintillata rubrifrons

The youth they are more muted than adults. Its head is slightly greenish with streaks pale. The bill is brown. The irises They are brown. The species is considered monotype.
They frequent humid subtropical forests., secondary forests and wooded meadows. Adapt quite well to cultivated land and the gardens in cities.
In Timor, they are relatively abundant between 1.000 and 2.300 meters above sea level, apparently, substitute to the Coconut Lorikeet in these heights. Also they can be observed at sea level in the island of Timor. In the rest of the Islands it frequents lowland areas.
The Olive headed Lorikeet they live in small groups. They are especially visible when they are in flight because they emit continuously shouts. On the other hand, when feeding or resting in trees, they are very difficult to observe because of their green plumage mixed with the color of the foliage.
They are birds territorial, capable of showing great aggressiveness if the limits of their area of โโinfluence are violated.
Usually disperse in search of their food, forming large groups when resources are abundant.
Outside the breeding season they form large roaming flocks of a hundred or more individuals.. Move in flying fast and slightly wavy.
In Timor, during the season, dry, These birds seem to descend below 1.000 meters and are scattered in coastal areas.
Reproduction:
The anidacio seasonn would take place perhaps between September and October, but this information needs to be confirmed.
In captivity, the Olive headed Lorikeet put 3 white eggs that parents are in charge of incubate for a few 23 days. As in the majority of the Lori, the nesting cycle is particularly long.
Food:
Feed primarily of nectar and fruit. They forage in trees in flower and shrubs.
Distribution:

Habitat:
Distributed by primary and secondary forests, tree savannas, plantations, Open forests, mangrove forests and farmland, a altitude of 1.400 m. Usually replaced by the Blue-collared Parrot at higher altitudes. Exclusive tropical jungle in the North of Australia. View the birds, generally, flying high above the trees, making calls to cries.
Groups of birds in the North of Australia, many still in family units, they have been observed leaving their roosts early, to feed into the dense jungle; in their flights to areas of foraging, We have seen some of these birds perched in the upper branches of the trees, by calling aloud for a few minutes and dithered wings before continuing. The reason for this unknown behavior can be a way of requesting food due to early maturation.
During the day the birds are less visible, they can draw attention by discarded food falling from their food trees.
They are usually in couples, in small groups or assembled in groups in fruit trees.
Reproduction:
The nest It is a hole that the birds excavate in a rotten limb of a tree from the forest, sometimes also in a knot in the trunk; probably only the female excavates. The entrance to the nest is of 80 to 90 mm. wide, and the tunnel, that it can twist in order to hide the eggs, You can have a length of 42 cm.. Includes the implementation of 2 to 4 eggs. The female alone incubates and is fed by the male during this time. In the West, the breeding season It takes place between April and September at least, month in which a live nest was found in Seram.
In New Guinea, the nesting is been registered during several months more, including February in the North and between the months of April to December in other places.
In Australia, in where the season seems to extend is from August to December, little information about the cycle reproductive is available.
It is known that the species It has never been raised successfully in captivity.
Food:
The diet It includes seeds, fruits and flowers. The birds tend to hang acrobaticamente to reach their food.
Distribution:
Size of the area of distribution (reproduction / resident): 793.000 km2
Generalized from the West of Lombok, through the Moluccas, the lowlands of New Guinea, and observed in the groups of associated Islands, to the East of Rossel in the Louisiade archipelago.
The species can also be observed in the northeast of the Cape York Peninsula, Australia, at its southern end, and North ranges up to Morotai in the North of the Moluccas. In many areas, throughout its distribution area, is the most abundant Parrot (rarer over the 800 meters above sea level), even around inhabited areas. Despite this, It may be extinct in Ambon.
The size of the world population It has not been quantified, Although it is estimated above 1.000.000 of copies. The species according to sources, is of common to abundant much of its area of distribution (pit et to the. 1997).
The population suspected to be stable in the absence of evidence of any reduction or substantial threats, Although you can that its population is affected by the capture in various parts of its area of distribution.
