One of the iconic small birds found across inland Australia is the green and yellow Budgerigar (Melopsittacus undulatus), commonly known as the budgie. Often seen in small groups, under the right climatic conditions, they can then be seen in flocks of hundreds to thousands.

Native to Australia, these small parrots are the only species in the genus Melopsittacus. They are green and yellow, have 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. They are known to have many colour mutations, including all yellow, blue and white. Some of the colour mutations could be the result of escaped captive birds that have interbred with the wild population.

A popular pet, they have been bred in captivity to include other colours such as blues, whites, yellows and greys.

Following image is of the male of the species. It is the adult male budgerigar whose cere (the area containing the nostrils) that is royal blue. In the female bird it is brown to white, although it is pink in the immatures birds of both sexes. In this image you can also see the iridescent blue-violet cheek patches.

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 Budgerigar are highly social birds in the wild, having a lifespan of up to 15 years in the wild. Those kept and bred as pets are also known to be highly social with humans.
