The budgerigar is a small parrot species belonging to the family Psittacidae, known for its social characteristics. Scientifically named Melopsittacus undulatus, this species is among the most popular pet birds worldwide. Its trainability, ability to mimic sounds, colorful plumage, and lively nature make it a preferred choice, especially as a household pet.
Native to Australia, this species has become one of the most widespread cage birds globally. In their natural habitat, they live in flocks and are found in open woodlands, shrublands, or arid regions. Domesticated forms have developed various color variations through years of breeding efforts. With proper care and nutrition, they can live up to 10 years.

Characteristics
Budgerigars are approximately 18 cm in length and weigh between 42–48 grams. They have short, stout, and curved beaks that allow them to crack hard seeds. While males and females appear similar externally, the cere (the fleshy area above the beak) is blue in males and brown or pink in females. They are lively, social, and interactive birds. Male budgerigars, in particular, have the ability to mimic human speech; therefore, pet birds that learn to talk are usually males. They are sometimes affectionately referred to as "lovebirds" due to their strong bonding behavior, although this term technically refers to another parrot species.

Distribution and Habitat
The budgerigar (Melopsittacus undulatus) is a native species unique to the Australian continent, and its natural distribution worldwide is limited to this continent. It is commonly found in the inland and central regions of Australia, especially in arid and semi-arid areas, open grasslands, sparsely shrubby plains, and savanna-like areas. The species is rarely found in tropical forests, dense woodlands, and coastal regions. Budgerigars exhibit a nomadic behavior, not staying in a fixed area year-round but they are not considered truly migratory birds; this movement primarily depends on the seasonal changes in water resources and food availability. During dry periods, they spread over large areas, moving towards water sources, while in rainy periods, they show a more scattered and settled distribution.
Behavior and Ecology
Budgerigars are highly social and can form strong bonds with both their own kind and humans. With proper training, they can mimic human sounds and simple words, and they can respond to melodies. In their natural environment, they are most active in the morning, rest during midday, and engage in communal chirping at the end of the day. Their flock flying and communal roosting are indicators of the species' social structure.
Reproduction
Budgerigars reach sexual maturity at around 6 months of age and can breed two or three times a year under suitable conditions. In their natural habitat, breeding usually coincides with the rainy season, a time when food resources are abundant and the survival chances of the young are high. The female budgerigar lays an average of 4 to 6 eggs per clutch. The incubation period lasts approximately 18–21 days, during which only the female sits on the eggs; the male supports her by providing food. The chicks fledge within 4–5 weeks but do not become fully independent in feeding until around the 7th week. They typically prefer tree hollows for nesting, a characteristic that allows the species to reproduce successfully in arid, wooded regions.

Nutrition
In their natural environment, the primary food source for budgerigars is seeds. Grass seeds and various types of herbs are the basic components of their diet. During rainy periods, their consumption of green plants increases. The diet of pet budgerigars includes grains and oilseeds such as millet, oats, flax seeds, and sunflower seeds. A balanced diet supplemented with vegetables and fruits like apples, carrots, spinach, and parsley is recommended. During their growth period, young birds can be given limited amounts of live food (e.g., small caterpillars), boiled eggs, or cheese as sources of animal protein. Cuttlebone or mineral blocks should be placed in the cage to meet their calcium needs. It is important to avoid sudden changes in their diet and to ensure that their food is fresh and their drinking water is clean. Disruption of their feeding regime can lead to weight gain and reproductive problems.
Conservation Status
According to the assessment by the International Union for Conservation of Nature (IUCN), the budgerigar is listed in the Least Concern (LC) category. This classification indicates that the species is not currently under any global threat. Natural populations in Australia are stable and quite resilient to environmental changes. Human impacts such as the clearing of agricultural land and the spread of water sources have even contributed to the creation of new suitable habitats for this species. However, outside their natural habitats (e.g., in intensive cage bird breeding systems), unsuitable breeding conditions and uninformed breeding practices can create limited problems for the welfare of the species. The budgerigar is one of the few parrot species that is not under threat of extinction due to its widespread breeding.
