These clear feathers are pure white in blue-series birds and yellow in birds of the green series. But usually there is no mistaking which dark factor category a budgie falls into, and the pictures below can be used as a guide. The yellowface type II variety has a bright yellow face. Also, the cere of the male dark-eyed clear does not change normally. The normal greywing has grey marking and 50% body color dilution. They are almost all clear. A genetically double-factor spangle budgie is all clear (all yellow or all white) with normal eyes (black with light irises at maturity). In the tufted crest, the feathers point up or backwards from the others near the front of the head, forming a tuft. When two spangle genes are present the budgie has no markings or color, and looks like a lutino/albino except for the red eyes. Full-body-color greywing budgies have the same grey markings of the greywing but the body color is brightened (not lightened or diluted). My pet budgies (parakeets) range in feather color from albino (white with red eyes) to pastels to dark blue and purple. There are four dilution alleles: normal, greywing, clearwing, and dilute. The yellow is confined to these areas only and the budgie is normally colored in the body feathers. In the Texas clearbody variety, the color of the budgie's body feathers is diffused or absent, and the wing markings are dark at the top and fade to a light grey toward the tips of the wings. Rr - One normal gene and one recessive pied gene (heterozygous) resulting in a normal budgie that is split for recessive pied. Adult male lutinos/albinos have purple ceres. Such a budgie is heterozygous and is said to be "split" for white-base, which means it carries the recessive gene, but does not show it because of the presence of the dominant gene. Some are more common among budgies bred for show. Adult female fallows have the normal white/tan/brown ceres. The band across the dominant pied's wings and belly can also be very small. With each progressive molt, more and more of the budgie's feathers grow back clear.

Visibly, legs and feet with poor circulation will appear swollen, perhaps, or if it’s just a toe, it may appear dry and necrotic (dead), possibly peeling and will feel cold to the touch. pied (PpRr)25% DEC with s-f clearflight (Pprr)25% Normal, split for rec. Here, we will represent the cinnamon gene on the Z-chromosome as "Zc" and the Z-chromosome with the normal gene as "Z". The cinnamon mutation does not affect the color of the body feathers​​​​, but sometimes can give them a cinnamony tinge. On the wings, instead of the normal black feathers with white edges creating the normal striping pattern, the feathers are mostly clear (yellow or white) with a thin black stripe at the edge. You can usually tell a green budgie has at least one violet factor. Grey factor creates grey-green in yellow-based budgies and grey in white-based budgies. The anthracite variety has black body color and black cheek patches. is availablein a new vervion A normal budgie and a single factor grey budgieggXGg, Offspring Phenotype Results:50% Grey Factor50% Normal, Offspring Genotype Results:50% Heterozygous (Gg)50% Homozygous recessive (gg), A normal budgie and a double-factor grey budgieggXGG, Offspring Phenotype Results:100% Grey Factor, Offspring Genotype Results:100% Heterozygous (Gg), Offspring Phenotype Results:75% Grey Factor25% Normal, Offspring Genotype Results:50% Heterozygous (Gg)25% Homozygous dominant (GG)25% Homozygous recessive (gg), A single factor grey budgie and a double factor grey budgieGgXGG, Offspring Genotype Results:50% Homozygous dominant (GG)50% Heterozygous (Gg). I’m happy to report that your bird seems to be perfectly normal, from what you have described and from your comparison to Peanut, my slate blue budgie. pied (ppRr), A s-f clearflight pied split for rec. A white-based budgie results in the common blue variety. These are sometimes called creamino. These Texas clearbodies are closer to the standard with no body color present. Observe the striping pattern on the head and wings, which are both the normal type. It is because females need only one gene to express the trait that sex-linked mutations such as cinnamon are more common in female budgies. This is the section you need to read! All budgies have a level of "dark factor" ranging from no dark factor, one dark factor, or two dark factors. A suffusion of the body color is slightly visible in the body feathers. If a budgie has a violet factor, you may or may not know it. Normal - dominantGreywing - recessive, co-dominant with clearwingClearwing - recessive, co-dominant with greywingDilute - recessive. This is how you can be sure a pied is recessive pied, since the dominant pied's eyes lighten normally with maturity.
