Habitat and behavior:

To the Swift Parrot It is usually seen in small groups of up 30 birds, sometimes in larger flocks (hundreds of birds) around the abundant food sources. There has also been some extraordinary reports in the enumeration of the flocks of more of 1.000 birds.

Are migratory birds. Are reproduced in Tasmania and then move to Australia continental, in autumn, for the non-reproductive season. Most of the population spends the winter in Victoria and New South Wales, before returning to Tasmania in spring. Usually they are gregarious in raising.

The playback area It is always within the 8 km from the coast, largely restricted to an area of less of 500 km² along the Western seaboard between Santa Helena and the Lune River, including offshore islands, as Mary Island and Bruny island.

The higher densities They occur between the After Bernier and Orford and Wellington Ridge about Hobart. A smaller breeding population is located in the North of Tasmania between Launceston and Smithton.

Reproduction:

Reproductive success is strongly related to the intensity and scope of the flowering of the Eucalyptus globulus (Tasmanian Blue Gum). In years of bad bloom, It seems that there is little breeding.

The breeding season It is mid-September to late January. Birds begin to return to Tasmania from your area of wintering on the continent at the beginning of August. Most of the population comes in mid-September. Unpaired birds upon arrival to Tasmania they can not start breeding until November after finding colleagues.

The De l'Tmño Nidada is three to five eggs. The female makes the incubation. in cautiverior incubation lasts about 25 days. Young people will fly in around 6 weeks. The presence of juveniles, recently fledged at the end of January and early February suggests double broods may occur. Second broods are dependent on the availability of food.

A recent study has shown that the nests of the Swift Parrot they are often found in close proximity together. Nest trees may be to only 10-15 m from, and can support up to four active nests each.

Food:

The Swift Parrot It feeds mainly on nectar, mainly of eucalyptus, but also feeds on insects Psyllids and lerps, seeds and fruits.

It is a tree Harvester, forages mainly in the eucalyptus, but from time to time low to the ground to feed on seeds, fallen flowers, fruit and Lerp. During the breeding season, the nectar from the flowers of the Eucalyptus globulus (Tasmanian Blue Gum) is the main source of food.

Sometimes they voraciously consume nectar in areas very accessible and this makes them reluctant to fly making them vulnerable to attack by cats, especially when forage among low foliage. His agility and alertness in flight can also be affected by the consumption of large quantities of nectar, possibly increasing the risk of collisions with artificial or hard-to-see objects.

Distribution:

Tamaño del área de distribución (reproducción/residente): 21.500 km2

The Swift Parrot, as its name suggests, migrates through the Bass Strait, between Tasmania and the Australian continent. Comes to Tasmania in September and returned to the southeast of Australia between March and April.

You can get to be as far north as the South-East of Queensland and get up to Adelaide from the West, Although the most recent sightings are restricted to the southeastern part of the State.

Conservation:

They estimated that the current population probably contains about 2.000 mature individuals and is declining.

The population of this species is suspected to be decreasing in line with the loss and degradation of habitat.
The gliding of the sugar they are the main predators of the broods of the Swift Parrot on the island of Tasmania, being the cause of the 85% of deaths, but they are not present on the Islands Bruny and Maria

• Current IUCN Red list category: Danger

• Population trend: Decreasing

The logging of a particular species is also responsible for the decline of population, eucalyptus, which constitute the 90% your diet.
