Budgerigar

The budgerigar ( BUJ-ər-ih-gar, -⁠ə-ree-; Melopsittacus undulatus), also known as the common parakeet, shell parakeet or budgie ( BUJ-ee), is a small, long-tailed, seed-eating parrot native to Australia. 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 (the sexes are visually indistinguishable), while adults are told apart by their cere colouring and their behaviour. The species is monotypic, meaning it is the only member of the genus Melopsittacus, which is the only genus in the tribe Melopsittacini. The budgerigar is closely related to lories and the fig parrots. The origin of the budgerigar'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 the wild and in captivity, budgerigars breed opportunistically and in pairs. They are found wild throughout the drier parts of Australia, where they have survived harsh inland conditions for over five million years. Their success can be attributed to a nomadic lifestyle and their ability to breed while on the move.
