context_page_description: The budgerigar is a long-tailed, seed-eating parrot usually nicknamed the budgie, or in American English, the parakeet. Budgies are the only species in the genus Melopsittacus. Naturally, the species is green and yellow with black, scalloped markings on the nape, back, and wings. Budgies are bred in captivity with colouring of blues, whites, yellows, greys, and even with small crests. Juveniles and chicks are monomorphic, while adults are told apart by their cere colouring, and their behaviour.
  The origin of the budgie's name is unclear. First recorded in 1805, budgerigars are popular pets around the world due to their small size, low cost, and ability to mimic human speech. They are the third most popular pet in the world, after the domesticated dog and cat. Budgies are nomadic flock parakeets that have been bred in captivity since the 19th century. In both captivity and the wild, budgerigars breed opportunistically and in pairs.
  It is found wild throughout the drier parts of Australia, where it has survived harsh inland conditions for over five million years. Its success can be attributed to a nomadic lifestyle and its ability to breed while on the move.
context_section_description: Breeding difficulties arise for various reasons. Some chicks may die from diseases and attacks from adults. Other budgerigars (virtually always females) may fight over the nest box, attacking each other or a brood. Another problem may be the birds' beaks being under-lapped, where the lower mandible is above the upper mandible.
  Most health issues and physical abnormalities in budgerigars are genetic. Care should be taken that birds used for breeding are active, healthy and unrelated. Budgerigars that are related or have fatty tumours or other potential genetic health problems should not be allowed to breed. Parasites (lice, mites, worms) and pathogens (bacteria, fungi and viruses), are contagious and thus transmitted between individuals through either direct or indirect contact. Nest boxes should be cleaned between uses.
  Splay leg is a relatively common problem in baby budgerigars and other birds; one of the budgerigar's legs is bent outward, which prevents it from being able to stand properly and compete with the other chicks for food, and can also lead to difficulties in reproducing in adulthood. The condition is caused by young budgerigars slipping repeatedly on the floor of a nest box. It is easily avoided by placing a small quantity of a safe bedding or wood shavings in the bottom of the nest box. Alternatively, several pieces of paper may be placed in the box for the female to chew into bedding.
