The Budgerigar (Melopsittacus undulatus) or "Budgie", is a small parrot (they are often called parakeets but actual parakeets are bigger) originating in Australia, where it occurs throughout the drier parts of the continent. It is 18 cm long and 26-29 g weight, and has a green body, blue tail, and yellow face; the wings have greenish-black flight feathers and black coverts with yellow fringes, this black-and-yellow feathering also on the upper mantle and nape. The legs are grey, with zygodactyl toes. The bill is pinkish-brown with a basal cere bluish in adult males, pinkish-brown in females and immatures. It is the only species in the genus Melopsittacus.
It occurs in a variety of open habitats, primarily in scrub, open woodland and grassland. Breeding can be at any time of the year following good rains which promote the growth of the grass and other plant seeds that comprise their diet. The nest is in a hole in a tree; the 4-7 eggs are incubated for 18 days, with the young fledging about 30 days after hatching. Outside of breeding, Budgerigars are highly nomadic, coveing extensive areas in small to very large flocks, seeking areas with good food resources. The nomadism also includes an element of migratory behaviour, with the far north of the range occupied in winter (June-September), and the far south in summer (September-January). Populations in some areas have increased as a result of increased water availability at farm livestock watering facilities.
The word budgerigar comes from the Kamilaroi Aboriginal Australian name for the species, gijirrigaa. An urban legend claims the name means "good food" or "good to eat".
Budgerigars in captivity
The Budgerigar is a very common and familiar pet. They have been bred to come in a wide range of mutations or colours, including green (the wild coloration), yellow, blue, white, violet, and others. They are relatively easy to care for, and can be taught to speak, whistle tunes, and play with their humans.
Close-up of a budgerigar in captivity In captivity, they can survive anywhere from 2 to 12 years, although there have been reports of budgerigars living for as long as 13 and 14 years. Their life span depends on the budgie's type (English budgies do not live as long as their cousins in Australia and America, due to years of inbreeding to change their size and features) and the individual bird's health (which is influenced by exercise and diet).
