* A molecular study published in 2015 by Gaynor Dolman and Leo Joseph He confirmed the genetic isolation of the subspecies Northiella haematogaster narethae and recommended that it was restored as a separate species, the Naretha Bluebonnet (Northiella narethae)
The Bluebonnet frequent arid and semi-arid forests dominated by trees of the genus Myoporum, which are perennial shrubs and resistant to salt and drought.
They also appreciate the conifer and the casuarinas that you are home to colonies of caterpillars. They have a certain affection for the acacias and eucalyptus, especially if the weed is made up of small quenopodios.
The Bluebonnet they often visit the grassy plains, dry brush and trees lining the river. Sometimes they come to buildings, farms or small ponds.
In the South of its range, the removal of waste bags of Mallee, located on agricultural land, It seems to have had a very important influence.
The Bluebonnet they live in pairs or in small groups. When resent, loud disperse, but they remain on the ground a short distance from the trees. In the event of alarm, they raise the feathers of her eyebrows.
These birds are very enable, especially early in the morning when the boisterous groups are formed, just before his departure to feed. They are able to run very fast and have a very characteristic straight posture.. They are less active during the heat of the day, staying on the ground in silence.
The Western populations They seem to form larger groups, showing more sociability than the Eastern. They tend to get together with other species of parrots, such as the Mulga Parrot, Pale-headed Rosella and Mallee Ringneck.
During the spawning, the Bluebonnet carried out parades such as greetings with head, movements of the tail and eating ritual exchanges. They also have a ceremonial flight consisting of small flapping.
The season of nesting extends from July to December, with some variations depending on the rains. The nest is located in a cavity in a tree, except in the subspecies narethae to use scrubby trees, being their favorite nesting place a nest on the ground in a crack in the base of a trunk. This subspecies usually gives preference to a tree of the genus acacia (Acacia papyrocarpa) family Fabaceae.
The spawning contains 4-7 eggs with one incubation lasts a few 19 days. The young chicks are born without feathers and remain in place of birth at least during 30 days.
The Bluebonnet consume mainly herbaceous seeds, of Atriplex hortensis, of coquia (Kochia scoparia), of bassia and some grown as garden plants.
Sometimes consume fruit, berries and acacia flowers, the mistletoe and the larvae of Lepidoptera that are attracted to the trunks of casuarinas.
When are juveniles, its menu consists mainly of seeds composed of helipterum, that you belong to the same family as sunflowers.
Endemic to Australia, where there are four populations, one of which is isolated in the southeast of Western Australia, from the West of the Nullarbor plain up close Kalgoorlie.
Birds belonging to this western race are also found in western Southern Australia, about Ooldea and Colon, but they are probably coming from exhausts. further east, the range of the species varies through the east of Southern Australia, from the West of Bordertown through Salt Creek, Adelaide, the northern parts of the Cape York Peninsula and Eyre, to the North across the basin of the Lake Eyre to the Simpson Desert, about Commonwealth Hill station (but largely absent from the Montes Flinders).
From the North of Southern Australia, extends to the South of Queensland to the West of the Great dividing range, reaching around to East of Windorah, Charleville, Mitchell and Goondiwindi.
In New South Wales found to the West of the Cordillera Central, and coming east of a line, More or less, that crosses Warialda, Orange and Wagga Wagga (record out of bounds east of Gunning).
In Victoria, from time to time, they arrive as far East as Rochester and Southeast of Bendigo and Beaufort.
The species is common within a suitable habitat.
The world population is probably superior to the 100.000 individuals, although the Western subspecies Nanthae You can have less than 5.000 specimens, having suffered for their catch in the past.
A small number of captivity.
Fully protected by law.
• Current category of the Red List of the UICN: Least concern
• Population Trend: Decreasing
In accordance with the Manual of the birds of the world (Handbook of the Birds of the World, HBW), the Bluebonnet they are not globally threatened. Son fairly common, except at the extremes of its range. But, the elucidation of native plants must be stopped if we want to preserve the food resources and nesting places.
The spread of the Common Starling (Sturnus vulgaris) It is a real danger in some areas. The subspecies Narethae is prized by poachers and the lots of beautiful feathers.
The proliferation of rabbits and Lagomorphs threatens the equilibrium of the habitat.
"Bluebonnet" in captivity:
The Bluebonnet they were classified for more than one hundred years within the genus Psephotus. On the basis of some essential differences with the species Psephotus, they are currently classified within the independent genre Northiella.
The parakeet more required by lovers of Australian parakeets, are likely to be the Bluebonnet, Although the subspecies Naretha is very rare and scarce. The Bluebonnet pure breed, they are virtually non-existent in Europe.
There are many Bluebonnet non-purebred, since they often interbreed with the of red-bellied (Northiella haematogaster haematorrhoa). The birds that have tones rojas in the coverts infracaudales non-purebred. Be very careful when making their acquisitions.
The first breeding success of the nominal species dates back to the year 1878, in France. With the subspecies of red-bellied (Northiella haematogaster haematorrhoa) also data from 1878, but this time in Belgium.
The first breeding results with the subspecies Northiella narethae they date from 1941 in Australia.
Are capricious in nature. The big problem is that of aggression since they are probably the most aggressive of all the Australian parakeets. Males, above all, they are the protagonists of this bad reputation. Therefore other birds not can be joined with the Bluebonnet, even larger birds.
The aggressiveness of the male reaches their own partner, the Aviary must take into account this, the female should be able to take refuge in case of attack. On the other hand, they are very animated and jugetones.
You spend much time on the ground looking for food, they are moderate rodents and are lovers of bath.
According to sources, a sample lived 15,3 years in captivity. In captivity, these animals have been known that they be reproduced in approximately 2 years of age.
