The standard for the Texas Clearbody (aka TCB) variety dictates that the body feathers should be devoid of colour, resulting in a predominantly yellow or white appearance, depending on the budgie’s base colour (either just white in blue/white based budgies, or just yellow in yellow/green based budgies).
The budgerigar (Melopsittacus undulatus)  also known as the common pet parakeet or shell parakeet and informally nicknamed the budgie, is a small, long-tailed, seed-eating parrot. Budgies are very easy to tame if acquired at a young age. Description: The budgerigar (Melopsittacus undulatus) also known as the common pet parakeet or shell parakeet and informally nicknamed the budgie, is a small, long-tailed, seed-eating parrot. Budgerigars are the only species in the Australian genus Melopsittacus and are found wild throughout the drier parts of Australia where the species has survived harsh inland conditions for the last five million years. Life Span: 10-15 Years Diet: Commercial Parakeet mix, canary seed, millets, oats groats, fruits and vegebles. Sexing: A mature male’s cere is usually light to dark blue. Females’ ceres are pinkish as immatures. As they age, they move from being beigish or whitish outside breeding condition into brown Breeding: Breeding is relatively easy as long as you have a true pair (male and female). Budgerigars feed one another by eating the seeds themselves, and then regurgitating it into their mate’s mouth. Female laid four to six eggs and incubates them for 18–23 days, with the young fledging about 30 days after hatching. Female budgerigars can lay eggs without a male partner, but these unfertilized eggs will not hatch. It is recommended to remove those eggs.
