Bred varieties

Sometimes escapes can be seen out in nature. The budgerigar shown below was found to hang out with a flock of House Sparrows.

There is something to nibble, too

Breeding information

Breeding season: June - Jan Eggs: 4 - 8 Incubation period: 17 - 23 days Fledging age: 28 - 35 days

Nest building: ? Incubation: Female Dependent care: Female & male


"bungobittah", "malunna" = nest [Aboriginal]

Type: Tree hollow Material: ? Height above ground: 2 - 10 m

Budgerigars can, in principle, breed any time after significant inland rain. They choose sites in both live and dead trees and often nest colonially. At prime nest sites, when there is a lot of pressure on available nest space, they can choose all kinds of cavities to nest in, also very low near the ground. The male feeds the female at the nest while she is incubating. This is the reason behind their elaborate "affectionate" bonding rituals that have earned Budgerigars the nickname "Lovebirds".

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 18 x 14 mm Colour: White Shape: Rounded


Social behaviour: Communal Mobility: Dispersive Elementary unit: Flock

Budgerigars are highly sociable and gregarious birds that will (especially after a successful breeding season) form flocks of many thousands. In such huge flocks the individual birds are well protected.

Bonding ritual at the start of the breeding season: Male Budgerigar feeding his partner, who will be reliant on him while incubating the eggs

Buderigars are nomadic, moving in and out of areas with seeding grass.

The farthest east we have seen Budgerigars was between Maules Creek, NSW, and Barraba, NSW, in March 2013 - here a photo of a small flock taken nearby

Food, Diet

Adults: Seeds Dependents: Regurgitated seeds Water intake: Daily

Like many parrots, Budgerigars are seed-eaters; primarily they take grass seeds.

Budgerigars are one of the few bird species that can ladle water into their throat using their tongue, similar to a cat, whereas most other bird species scoop water into their lower mandible.
