Environment and behaviour:
The Bourke's parakeet has a preference for dry and semi-dry areas overgrown with acacia bushes, where no more than 250 mm of rain falls per year. It is considered a typical example of species living in the Australian interior. Under ideal feeding conditions (after sufficient rain), density increases in the distribution area, and it decreases as soon as the food supply is poor. In nature, these birds are rarely encountered, as they live in areas little visited by humans, and are active in the early morning hours and at dusk. During this time, their protective colouring makes them even less conspicuous. At night, especially in clear nights, they also start moving and you can hear the beating of their wings in flight. These nocturnal excursions also explain the large eyes of these parakeets. Most often Bourke's parakeets fly in pairs or small groups, but in dry times they can be found in flocks of more than a hundred individuals at watering places. They roam around depending on the weather and it is extremely difficult to specify where these birds may be encountered. They have retained their behaviour in the aviary. During the day they behave quietly, and in the early morning hours and at sunset they become active.
Subspecies:
Currently there are four mutations of the Bourke's parakeet: yellow, isabell, fawn and pink. The yellow Bourke shows a delicate yellow colouring on its back and wings, and the head and chest appear matt pink. The claws are very light, almost transparent. The males are a little darker than the females, which appear yellowish. Inheritance is autosomal recessive. The isabell is very similar to the yellow Bourke. The colour is more pink and less yellow, and the yellow has a rather brownish character. Feet and claws are greyish. Like the yellow, the isabell has red eyes. Inheritance is sex-linked recessive.
Sexual difference:
Males: Upper side brownish, breast pink with brown, belly pink, feathers with brownish edges. Forehead band, shoulders, underwings, undertail coverts, thighs and flanks blue, wings and central tail feathers grey-olive, outer tail feathers white with blue edges. Beak horn coloured, iris brown, legs grey-brown.
Females: duller in colour, blue forehead band missing, white wing stripe present.
Keeping:
To make Bourke's parakeets feel comfortable you need:
- Aviary
- Perches of various thicknesses or natural branches (willows, poplars or fruit trees)
- Sleep box - must be removed in case of excessive breeding drive
- Bathing or showering facility
- Food and drinking bowl
Food:
Bourke's parakeets search for their food mainly on the ground. Their food consists of the seeds of grasses, herbaceous plants, shrubs and trees. Occasionally they also catch insects.
- Mineral stone - serves to cover the calcium requirement
- Bird sand - contains important components for digestion
- unsprayed wild herbs (e.g. chickweed / knotweed / shepherd's purse / young dandelion)
- Millet on the cob (once a week, as the fat content is high, otherwise the Bourke's parakeets suffer from obesity).
- Egg food and germ food - indispensable during the breeding season
- Crackers and nibble sticks are healthy treats which ensure that the bird has to work for its food.
Food, water and fresh food must be renewed daily.
Breeding:
In nature, they look for tree hollows at one to three metres, and the entrance to a Bourke's nest has also been found at 30 cm. In the aviary, a nest box 30 cm high with a base area of 15 x 15 cm should be installed. The entrance hole should have a diameter of 5 cm.
The Bourke is an uncomplicated breeder that can be bred in colonies, but pairs should be kept individually. After choosing the nest site, the female lays three to six eggs and stays on the clutch for about eighteen days. She leaves the nest at most once a day to eat, to be fed by the male, and to defecate. Once the young have fledged after four weeks, they stay with the parents for some time in the wild. As Bourke's parakeets can be quite productive and breed several times in quick succession, the independent young should be housed elsewhere when a new clutch appears. During the breeding period, the nesting material may need to be renewed, as these parakeets do not keep their nursery particularly clean.
Swiss animal welfare legislation contains legal requirements that regulate the animal-friendly keeping of and handling with birds.
The following regulations apply to all types of birds:
- social species must be kept socially (no solitary keeping)
- the enclosures must comply with the minimum sizes = minimum requirements
- all birds must be offered a bathing opportunity
- the enclosures must be structured with various, springy perches of different thicknesses and alignments, with one third of the volume being free of structures
- all birds must be provided with suitable sand for ingestion
- private keeping of certain species of birds requires a licence (wild animal keeping licence)
- the keeping of parrots in stands and the keeping of song canaries in Harzer cages is prohibited
- the use of sand sleeves as a covering for perches is prohibited
for parrots:
minimum enclosure area for 4 small parakeets and agapornids
0.24 m2 (e.g. 60 cm x 40 cm), minimum height 50 cm
Parrots require plenty of natural branches for gnawing and climbing
Regular costs (per month/for 2 animals):
- Food: approx. Fr.15.--
- Sand: approx. Fr. 10.--
- Veterinarian: The more appropriate and cleaner the keeping, the less often you have to go to the vet. Nevertheless, you must always expect that an animal can also become ill and then causes additional costs.
Before you decide on Bourke's parakeets, you should definitely read an appropriate reference book.
For all animal keeping: children must be guided, supervised and controlled by their parents. Children must learn that an animal has its own needs and habits and respect this. Parents should be aware that they are the ones who are responsible for the animal.
