In the Budgerigar (Melopsittacus undulatus) of adults, the cere Blue contrasts with the frontal zone; the front of the face and throat are pale yellow. The latter is covered by a line of black dots. The area which is located below the cheeks it's purple.

The central part of the pileum extending from the rear of the eyes to neck It is covered with alternating thin black bands and bands of pale yellow. These bars are expanded on the the mantle and wing-coverts, forming a scaly effect.

The female has a Brown wax.

The immature they are more turned off with bars on the front. The black spots on the throat they are absent.


The Budgerigar they are distributed by a wide variety of open habitats, including open forests, lightly wooded grasslands and savannas. Also appreciate the areas of Mallee, farmland, vegetation that grows along rivers, drought-adapted scrub and open plains. They come fitted with desert areas of Mulga (Acacia aneura). Although they are able to survive several days without water, These birds are never far from a water source.

In areas where fruit production is constant and in others where it is stable for very long periods, the movements of the Budgerigar they are easily predictable.

In the South end, Pilgrimages exist only in cases of prolonged drought and wandering parakeets return to their territory with the first rains and recolonize when river levels return to normal.


The Budgerigar they build their nests of June to September in the North its area of distribution. They reproduce between August and January in the South. Nests can be installed at any time of the year after the rains fall. They establish a second brood as soon as conditions are favorable.

These parakeets usually nest in colonial way. The nest is located in a natural cavity in a tree, in a strain, an any fence post, or on a big fallen branch.

The female lays from 4 to 6 eggs and incubation lasts a few 18 days. The chicks remain in place of birth during 30 days before flying.


The Budgerigar It vegetarian, they eat herbs and seeds of quenopodios. Plants vary in categories and in proportions, according to which regions and times.

The East inside of Australia, These birds feed exclusively on seeds that are on the ground, While in the middle of the continent, There is more variety of plants to select. In the first case, grain size barely exceeds the 2 mm diameter and the second, more than 40 plant varieties make up the diet of these parakeets.

From time to time, the Budgerigar, they come in growing areas and take advantage of the ripe fruits.


The Budgerigar are distributed widely throughout the Interior of Australia, Although they are rare in the coastal districts of the This and the end South-West (absent of Tasmania, Arnhem Land and Cape York Peninsula).

The species may be of common to very abundant, but they are nomadic, and may change from year to year areas.

These parakeets, frequently, they burst from the arid zones to the more humid zones and there are temporary movements towards the south during the summer, but these changes may be affected by annual rainfall patterns.

We have introduced, without success, in a number of places around the world (or they have escaped from captivity and could not be) including South Africa, United Kingdom, Japan, Hong Kong, Puerto Rico, Brazil, Switzerland, Colombia, the Society Islands, New Zealand and Oman.

In the EE.UU. the species has managed to colonize Hawai and California (leaks also occur regularly in the city of New York City). In Florida a population was originally registered in the area of St. Petersburg, in the decade of 1950 and now has more of 3.000 individuals; These birds are mobile and have been recorded along the coast This of all the South from Jacksonville to Miami, and in the West everything Hudson to South of Fort Myers, from time to time go towards the North in Gainsville.

Parakeets, occasionally escaped, they may appear in Tasmania.

The world population is estimated at around 5.000,000 copies.



• Current category of the Red List of the UICN: Least concern

• Population Trend: Growing

This species is not threatened at all, even they are abundant, and in some places where resources are good, countless flocks darken the sky, to cause branches to break from 4 centimeters in diameter, When large number of birds used them as support for their breaks.

Populations fluctuate widely depending on weather conditions.

Livestock living on farms in central Australia have caused Budgerigar they will benefit from new water supplies. Like this, the number of parakeets are constantly increasing.

These parakeets are the most well known psittacidas in the world.

"Budgerigar" in captivity:

This parakeet was discovered in 1805 and since then it has become the most popular captive bird in the world. While it is considered as domestic fowl, However, is a gregarious and instinctive animal, with the same needs that the parrots who freely roam the lands of Australia.

The Budgerigar It dynamic, curious, melodious and because of its small size, the beauty of their plumage and their entertaining behaviour, truly charming. This is what makes it a coveted bird. But, It is still a bird that needs to fly, play and socialize with their peers. Like any bird, It is sensitive to the social and environmental context. In fact, their real needs are too often overlooked, many parakeets suffer neglect or even abuse.

In captivity, the Budgerigar It is larger than its counterpart in nature. Measures of 20 to 25 cm. from head to tail and weighs between 30 and 45 g.. In addition to the colour of your coat, wild type, There are numerous mutations (other coat colors) associated with the increase in crossings and selections in certain genes, that translates into more spontaneous mutations.

The Budgerigar has two silent by year average, and the first moult occurs between the fourth and sixth month. The molt is complete renovation of the plumage of the bird. Pens fall to others push, includes your tube of keratin that parakeets will open with their beaks to release pen and relieve the irritation that engenders the same thrust. It can be more or less painful and intense. Some plucking is so fast that the bird may experience some difficulties during the flight.

Check the intensity of the change of the parakeet through black head tubes, tiredness and especially the number of feathers on the ground.

The feeding of the Budgerigar is based on the millet and the birdseed, Although it must be complemented with other seeds or vegetables (as the lettuce, Spinach, pepper, Carrot, corn). The fruits are also a good dietary supplement for these birds. Occasionally it can provide a little bread or biscuit, but always with caution that not give them anything very sweet. The avocado, the chocolate and the parsley they are deadly toxic for the Australian parakeets.

The the parakeet cage must be protected from the cold, a temperature between the 20-25 C. It must be of one sufficient size so you have freedom of movement and can exercise. The balusters must be arranged horizontally so that they can climb up them. The cage must be washed at least once a month with a disinfectant, change the water daily and clean the shells of the food. A cat litter tray can be placed to make their needs.
It is also important to let the parakeet out occasionally and fly freely around the room. Windows must be closed and curtains, because you can hit them.
Son very sociable birds and it is better to live with other parakeet. The best couple is formed by a male and a female. This will try to kill its companion if it is of the same gender.

With regard to its longevity, according to sources, these animals can come to live until 21 years in captivity. The same sources indicate that these parakeets suffer from a high incidence with respect to ovarian cancer.
