Budgerigar - 虎皮博物馆 - 虎皮博物馆
 
The Budgerigar (Melopsittacus undulatus, nicknamed budgie), the only species in the Australian genus Melopsittacus, is a small parrot belonging to the tribe of the broad-tailed parrots (Platycercini); these are sometimes considered a subfamily (Platycercinae). In the latter case, the Budgerigar is sometimes isolated in a tribe of its own, the Melopsittacini, although it is probably quite closely related to Pezoporus and Neophema. Though Budgerigars are often called Parakeets, especially in American English, this term refers to any of a number of small Parrots with long flat tails. The Budgerigar is found throughout the drier parts of Australia and has survived in the inlands of that continent for over 5 million years. 

The Budgerigar is one of the two Parrots to be genuinely domesticated as a species along with the Peach-faced Lovebird (Agapornis roseicollis). Believed to be the most common pet Parrot in the world, the Budgerigar has been bred in captivity since the 1850s. Breeders have worked over the decades to produce a wide range of colour, pattern and feather mutations, such as blue, white, violet, olive, albino and lutino (yellow), pied, clearwing, spangled, and crested. 

Modern show budgerigars, also called English budgerigars and/or Standard-Type Budgerigars are larger than their wild-type (natural form) counterparts, with puffy head feathers, giving them an exaggerated look. The eyes and beak can be almost totally obscured by feathers. Most Budgerigars in the pet trade are not of the show variety (Standard-Type aka English Budgies) and are similar in size and body conformation to wild Budgerigars and thus aptly called wild-type Budgies. 

Budgerigars are intelligent and social animals and enjoy the stimulation of toys and interaction with humans as well as with other Budgerigars. A common behaviour is the chewing of material such as wood, especially for female Budgerigars. 

Budgerigars can be taught to speak, whistle tunes, and play with humans. Both males and females sing and can learn to mimic sounds & words. Both singing and mimicry are more pronounced and much more perfected in males. As a whole, females rarely if ever learn to mimic more than a dozen words or so. Males can very easily acquire vocabularies ranging between a few dozen to a hundred words. Generally speaking, it is the pet Budgies and even more so the ones kept as single pets which talk the best and the most. 

In captivity, Budgerigars live an average of five to eight years, but are reported to occasionally live to 15 if well cared for. The life span depends on the budgerigar's breed (show Budgerigars typically do not live as long as wild-type Budgerigars) and on the individual bird's health, which is highly influenced by exercise and diet. 

Although wild Budgerigars eat grass seeds almost exclusively, avian veterinarians recommend captive birds' diets be supplemented with foods such as fresh fruits and vegetables, sprouted seeds, pasta, whole grain bread and other healthy human foods, as well as pellets formulated for small parrots. Adding these foods provides additional nutrients and can prevent obesity and lipomas, as can substituting millet, which is relatively low in fat, for seeds mixes. Budgerigars do not always adapt readily to dietary additions, however. Chocolate and avocado are recognized as potential toxins.
