A small parrot, they are usually green and yellow, with a beautiful scalloped pattern on the upperparts of their body and fine barring on the head.

Their heads also have iridescent blue-violet cheek patches, with a series of three black spots on each side of the throat (called throat patches). Their tail is a beautiful dark cobalt blue, with outside tail feathers displaying central yellow flashes.

The adult male budgerigar cere (the area containing the nostrils) is royal blue. In the female bird it is brown to white, although it is pink in the immatures birds of both sexes.

In the wild they naturally live in trees, often making nests in knots or other depressions, as well as small holes in trunks of trees, that are just large enough to hold their nests.

The Budgerigars are highly social birds in the wild, with a lifespan of up to 15 years in the wild.
