|Common Name||Bourke's Parakeet, Bourke and "Bourkie"|
The Bourke's parrot (Neopsephotus bourkii, formerly known as Neophema bourkii), also known as the Bourke's parakeet, Bourke or "Bourkie", is a species of small parrot originating in Australia and the only species in its genus Neopsephotus. This species is sometimes placed in the genus Neophema and there is an ongoing discussion about the proper taxonomic placement of this species. It is a grass parrot approximately 19 cm long and weighing around 45 grams. It is named after General Sir Richard Bourke, Governor of New South Wales from 1831 to 1837.
The Bourke’s parrot was originally classified within the genus of Neophema which fully consists of grass parakeets. However, in the mid-90s the Bourke’s was reclassified into and is the only member of the Neopsephotus genus. The reasoning behind this reclassification was because the Bourke’s parrot was unable to hybridize with any of the other Neophema species; they are different in colouration and live a nomadic lifestyle throughout the arid regions of Australia. The Bourke’s parrot is still however referred to as a type of grass parakeet.
The Bourke’s parrot is a relatively small species. They tend to vary between 18 cm and 23 cm in length with a tail length of approximately 9 cm. The females of the species tend to be slightly smaller than the males. The males of the species weigh between 47 g and 49 g whilst the females weigh between 41 g and 49 g. Young birds under nine months of age both male and female look very similar, after this they come into full plumage colour. Wildtype (natural coloured) Bourke's parakeet display a basically brown overall colouration with pink abdomen, pinkish breast and a blue rump. The legs are dark-brown, with zygodactyl toes. The bill is yellowish-brown. The adult male has a blue forehead while the adult female has a little or no blue on the forehead. The Bourke's parrot's feathers help the species blend in with the reddish soil of its home. There are four documented mutations found in captive Bourke’s parrots; yellow, Isabel, fallow and pink or rosa. The Bourke’s parrots call is rather frequent and sounds like a mellow ‘chu-vee’. Banding of this species requires a 4 mm band.
Distribution and Habitat
The Bourke’s parrot is nomadic species native to Australia. It has a vast range and tends to be located in sparsely populated areas across Australia; however they have been known to dwell in urban areas as well. These parrots can be found from the South-western parts of Queensland deep into western New South Wales, throughout central Australia to the far northern parts of South Australia and parts of Western Australia. The Bourke’s parrot’s main habitat consists of areas dominated by Mulga and Acacia species in dry spinifex plains. The species can also be found in native cypress and other open eucalypt woodlands.
Bourke's parrots forage on the ground for grasses and seeds. They are most active feeding at dusk and dawn. Captive birds can be fed a number of different things including small parrot seed mixes, hard-boiled eggs, fresh twigs and buds (ensure these are of a non-toxic nature before feeding them to any bird), fresh fruit and greens.
Breeding season for the Bourke’s parrot tends to occur between the months of August and October but can draw out into December depending on the season and availability of resources. Nests tend to be situated from 1 metre to 3 metres above ground level in hollow limbs of the Mulga tree or Acacia. Eggs are generally laid on a bed of decayed wood at the bottom of the tree hollow. The Bourke's parrot has a clutch of 3 to 6 eggs, which are incubated by the female for 18–19 days, with the chicks fledging at about 4 weeks of age. Once the chicks hatch both parents feed their young. Offspring become fully independent around 8 to 10 days after fledging. While the female Bourke's parrot is incubating the eggs she is fed by the male Bourke's parrot, only leaving the nest to find water or to defecate.
