Introduction:

• When it comes to pet birds, budgerigars have been popular options for years. These small parrots can be found in just about any pet store, but they're generally only found in the wild in Australia. Although it's not unusual to run across budgerigars of many different colors and patterns, those variations have come about through strategic, carefully planned breeding through the years. Despite their diminutive size, these birds make fascinating pets. They have been charming people for years with their playful personalities, gorgeous coloring, intelligence and sociability. Budgerigars are affordable pets, and they are easy to care for as well.
• With budgerigars, there's a lot more than meets the eye. Until you've actually taken the time to get to know a budgerigar, it's easy to assume that they are like any other bird. In the wild, budgerigars are prized for their bright, vibrant feathers. In captivity, they are popular for being easy, fun pets to have in the home. People have been breeding budgerigars for decades to develop exciting new color variations and markings. If you're thinking about adopting one, you can take your pick from more than 100 different variations. Before you do that, though, study up about this fascinating bird below.

Other names

The budgerigar was first described by George Shaw in 1805, and given its current binomial name by John Gould in 1840. The genus name Melopsittacus comes from Greek and means "melodious parrot". The species name undulatus is Latin for "undulated" or "wave-patterned".

Alternative common names for the budgerigar include the shell parrot, the warbling grass parakeet, the canary parrot, the zebra parrot, the flight bird, the scallop parrot. Although more applicable to members of the genus Agapornis, the name lovebird has been applied to them from their habit of mutual preening.

The budgerigar has been bred in captivity since the 1850s. Breeders have worked to produce a variety of colour, pattern, and feather mutations, including albino, blue, cinnamon-ino (lacewinged), clearwinged, crested, dark, greywinged, opaline, pieds, spangled, dilute (suffused), and violet.

English or "show" budgerigars are about twice as large as their wild counterparts, and with a larger size and puffier head feathers have a boldly exaggerated look. The eyes and beak can be almost totally obscured by these fluffy head feathers. English budgerigars are typically more expensive than wild-type birds, and have shorter life span of about seven to nine years. Breeders of English budgerigars often exhibit their birds at animal shows. Most captive budgerigars in the pet trade are more similar in size and body conformation to wild budgerigars.

Budgerigars are social animals and require stimulation in the shape of toys and interaction with humans or with other budgerigars. Budgerigars, and especially females, will chew material such as wood. When a budgerigar feels threatened, it will try to perch as high as possible and to bring its feathers close against its body in order to appear thinner.

Tame budgerigars can be taught to speak, whistle, and play with humans. Both males and females sing and can learn to mimic sounds and words and do simple tricks, but singing and mimicry are more pronounced and better perfected in males. Females rarely learn to mimic more than a dozen words. Males can easily acquire vocabularies ranging from a few dozen to a hundred words. Pet males, especially those kept alone, are generally the best speakers.

Budgerigars will chew on anything they can find to keep their beaks trimmed. Mineral blocks (ideally enriched with iodine), cuttlebone, and soft wooden pieces are suitable for this activity. Cuttlebones also supply calcium, essential for the proper forming of eggs and bone solidity. In captivity, budgerigars live an average of five to eight years, but life spans of 15–20 years have been reported. The life span depends on breed, lineage, and health, being highly influenced by exercise and diet. Budgerigars have been known to cause "bird fancier's lung" in sensitive people, a type of hypersensitivity pneumonitis.

Breeding

Breeding in the wild generally takes place between June and September in northern Australia and between August and January in the south, although budgerigars are opportunistic breeders and respond to rains when grass seeds become most abundant. They show signs of affection to their flockmates by preening or feeding one another. Budgerigars feed one another by eating the seeds themselves, and then regurgitating it into their flockmate's mouth. Populations in some areas have increased as a result of increased water availability at farms. Nests are made in holes in trees, fence posts, or logs lying on the ground; the four to six eggs are incubated for 18–21 days, with the young fledging about 30 days after hatching.

In the wild, virtually all parrot species require a hollow tree or a hollow log as a nest site. Because of this natural behavior, budgerigars most easily breed in captivity when provided with a reasonable-sized nest box. The eggs are typically one to two centimetres long and are pearl white without any colouration if fertile. Female budgerigars can lay eggs without a male partner, but these unfertilised eggs will not hatch. Females normally have a whitish tan cere, however when the female is laying eggs, her cere turns a crusty brown colour. Certain female budgies may always keep a whitish tan cere or always keep a crusty brown cere regardless of breeding condition. A female budgerigar will lay her eggs on alternate days. After the first one, there is usually a two-day gap until the next. She will usually lay between four and eight eggs, which she will incubate (usually starting after laying her second or third) for about 21 days each. Females only leave their nests for very quick defecations, stretches and quick meals once they have begun incubating and are by then almost exclusively fed by their mate (usually at the nest's entrance). Females will not allow a male to enter the nest, unless he forces his way inside. Depending on the clutch size and the beginning of incubation, the age difference between the first and last hatchling can be anywhere from 9 to 16 days. At times, the parents may begin eating their own eggs due to feeling insecure in the nest box.

Chick health

Breeding difficulties arise for various reasons. Some chicks may die from diseases and attacks from adults. Other budgerigars (virtually always females) may fight over the nest box, attacking each other or a brood. Sometimes, budgerigars (mainly males) are not interested in the opposite sex, and will not reproduce with them; a flock setting—several pairs housed where they can see and hear each other—is necessary to stimulate breeding. Another problem may be the birds' beaks being under lapped, where the lower mandible is above the upper mandible.

Most health issues and physical abnormalities in budgerigars are genetic. Care should be taken that birds used for breeding are active, healthy, and unrelated. Budgerigars that are related or which have fatty tumours or other potential genetic health problems should not be allowed to breed. Parasites (lice, mites, worms) and pathogens (bacteria, fungi and viruses), are contagious and thus transmitted between individuals through either direct or indirect contact. Nest boxes should be cleaned between uses.

Splay leg is a relatively common problem in baby budgerigars and other birds; one the budgerigar's legs is bent outward, which prevents it from being able to stand properly and compete with the other chicks for food, and can also lead to difficulties in reproducing in adulthood. The condition is caused by young budgerigars slipping repeatedly on the floor of a nest box. It is easily avoided by placing a small quantity of a safe bedding or wood shavings in the bottom of the nest box. Alternatively, several pieces of paper may be placed in the box for the female to chew into bedding.

Development

Eggs take about 18–20 days before they start hatching. The hatchlings are altricial – blind, naked, unable to lift their head, and totally helpless, and their mother feeds them and keeps them warm constantly. Around 10 days of age, the chicks' eyes will open, and they will start to develop feather down. The appearance of down occurs at the age for closed banding of the chicks. Budgerigar's closed band rings must be neither larger nor smaller than 4.0 to 4.2 mm.

They develop feathers around three weeks of age. (One can often easily note the colour mutation of the individual birds at this point.) At this stage of the chicks' development, the male usually has begun to enter the nest to help his female in caring and feeding the chicks. Some budgerigar females, however, totally forbid the male from entering the nest and thus take the full responsibility of rearing the chicks until they fledge.

Depending on the size of the clutch and most particularly in the case of single mothers, it may then be wise to transfer a portion of the hatchlings (or best of the fertile eggs) to another pair. The foster pair must already be in breeding mode and thus either at the laying or incubating stages, or already rearing hatchlings.

As the chicks develop and grow feathers, they are able to be left on their own for longer periods of time. By the fifth week, the chicks are strong enough that both parents will be comfortable in staying out of the nest more. The youngsters will stretch their wings to gain strength before they attempt to fly. They will also help defend the box from enemies, mostly with their loud screeching. Young budgerigars typically fledge (leave the nest) around their fifth week of age and are usually completely weaned between six and eight weeks old. However, the age for fledging, as well as weaning, can vary slightly depending on whether its age and the number of surviving chicks. Generally speaking, the oldest chick is the first to be weaned. Though it is logically the last one to be weaned, the youngest chick is often weaned at a younger age than its older sibling(s). This can be a result of mimicking the actions of older siblings. Lone surviving chicks are often weaned at the youngest possible age as a result of having their parents' full attention and care.

Hand-reared budgies may take slightly longer to wean than parent-raised chicks. Hand feeding is not routinely done with budgerigars, due to their small size, and because young parent raised birds can be readily tamed.

Colour mutations

Main article: Budgerigar colour genetics

Adult females (top) display beige to brown ceres, while adult males (bottom) typically have blue ceres or purplish-pink in albinistic and recessive pied varieties.

All captive budgerigars are divided into two basic series of colours; namely, white-based (blue, grey and white) and yellow-based (green, grey-green and yellow). Presently, at least 32 primary mutations (including violet) occur, enabling hundreds of possible secondary mutations (stable combined primary mutations) and colour varieties (unstable combined mutations).

Mimicry

Main article: Talking bird

Male specimens of budgerigars are considered to be one of the top five talking champions amongst parrot species, alongside the African grey, the amazon, and the eclectus parrots, and the ring-necked parakeet.

Puck, a male budgerigar owned by American Camille Jordan, holds the world record for the largest vocabulary of any bird, at 1,728 words. Puck died in 1994, with the record first appearing in the 1995 edition of Guinness World Records.

In 2001, recordings of a budgerigar called Victor got some attention from the media. Victor's owner, Ryan B. Reynolds of Canada, stated Victor was able to engage in contextual conversation and predict the future. Though some believe the animal was able to predict his own death as was claimed, further study on the subject is difficult without the bird. The recordings still remain to be verified by scientific analysis. Critics argue Victor's speech in the recordings is not coherent enough to be determined as spoken in context.
