The Budgerigar (Melopsittacus undulatus, nicknamed budgie), the only species in the Australian genus Melopsittacus, is a small parrot belonging to the tribe Melopsittacini in the subfamily of the broad-tailed parrots (Platycercinae). Though budgerigars are often called parakeets, especially in American English, this term also refers to any of a number of small parrots with long flat tails. The budgerigar is found throughout the drier parts of Australia and has survived in the inlands of that continent for over 5 million years.

Etymology


At least two possible origins for the English name budgerigar have been proposed:

The genus name Melopsittacus comes from Greek and means "singing parrot". The species name undulatus is Latin for "undulated" or "wave-patterned".

Characteristics


Bluemalecere.jpg Budgerigars are about 18 cm long and weigh 30-40 grams. Wild budgerigars have green underparts and rumps, while the upperparts are barred with black and yellow. The forehead and face is yellow in adults, and barred black with yellow in young till they change into their adult plumage at 3-4 months of age. Each cheek has a small dark purple patch and a series of black spots across the throat. The tail is greenish blue or purple; outside tail feathers have a central yellow band. Their wings have greenish-black flight feathers and black coverts with yellow fringes. Bill olive grey and legs greyish blue, with zygodactyl toes.

The colour of the cere (the area containing the nostrils) differs between the sexes; blue in males, pink (non-breeding) or brownish (breeding) in females.

Colours

Budgerigars are available in many different colours. Some colour mutants, such as yellow (lutino) and blue, are determined by a single gene and have arisen spontaneously. Combining mutations can result in new colours (lutino and blue results in albino) as well as new breeds. Other colour variants are the result of selective breeding resulting in more complex patterns. Using the cere to determine the gender of birds with certain colour mutations such as albinos or lutinos is less reliable; these birds have ceres that can look pinkish or have a purple tinge.

Habitat and behaviour


Budgerigars are nomadic birds found in open habitats, primarily in Australian scrubland, open woodland and grassland. The birds are normally found in small flocks, but can form very large flocks under favourable conditions. The species is extremely nomadic and the movement of the flocks is tied to the availability of food and water. Drought can drive flocks into more wooded habitat or coastal areas. They feed on the seeds of spinifex, grass weeds, and sometimes ripening wheat.

Breeding takes generally place between June and September in the North and between August and January in the South but they are opportunistic breeders responding to the rains when grass seeds become most abundant. Populations in some areas have increased as a result of increased water availability at farms. The nest is in a hole in a tree, fence post or even a log laying on the ground; the 4-6 eggs are incubated for 17-19 days, with the young fledging about 30 days after hatching.

Both male and female budgerigars sing and can learn to mimic sounds, although both singing and mimicry are more pronounced in males.

Budgerigars in captivity


The budgerigar is one of the few parrots to be domesticated as a pet. Believed to be the most common pet parrot in the world, it has been bred in captivity since the 1850s. Breeders have worked over the decades to produce a wide range of colour and feather mutations, such as yellow, blue, white, violet, olive, albino and lutino (yellow), clearwing and spangled. Feather mutations can produce crests or overly long shaggy feathers known as "feather dusters".

Modern show budgerigars, also called English budgerigars, are larger than their wild cousins, with puffy head feathers, giving them an exaggerated look. The eyes and beak can be almost totally obscured by feathers. Such birds are reported to be more prone to genetic mutations because of inbreeding. Most budgerigars in the pet trade are not of the show variety and are similar in size and body conformation to wild budgerigars.

Budgerigars can be taught to speak, whistle tunes, and play with humans. They are intelligent and social animals and enjoy the stimulation of toys and interaction with humans as well as with other budgerigars. A common behaviour is the chewing of material such as wood, especially for female budgerigars.

In captivity, budgerigars live an average of five to eight years, but are reported to occasionally live to 15 if well cared for . The life span depends on the budgerigar's breed (show budgerigars typically do not live as long as the common budgerigars) and the individual bird's health, which is influenced by exercise and diet.

Although wild budgerigars eat grass seeds almost exclusively, avian veterinarians recommend supplementation with foods such as fresh fruits and vegetables, sprouted seeds, pasta, whole wheat bread and other healthy human foods, as well as pellets formulated for small parrots. Adding these foods provides additional nutrients and can prevent obesity and lipomas, as can substituting millet, which is relatively low in fat, for seeds mixes. Budgerigars do not always adapt readily to dietary additions, however. Chocolate and avocado are recognized as potential toxins. Plums, lemons, limes, and members of the cabbage family are bad for them as well. Recommended fruits and vegetables are apples, oranges, bananas, strawberries, carrots, unsprayed lettuces, parsley, and spinach.

"Context speaking" budgerigars


In 2001, budgie owner Ryan B. Reynolds of Ontario, Canada received much publicity due to his release to the press of certain recordings of his talking budgie, Victor. In these recordings, Victor performed what appeared to be "speaking in context". To the layperson, the recordings appeared to audibly demonstrate that Victor was able to use his 1000+ word vocabulary to express coherent lines of thought, meaning and reasoning. Despite the widespread TV, newspaper and radio publicity the recordings received in 2001, the recordings have yet to be scientifically analysed, proven, (or disproven) publication date: 23 Mar. 2006.
