Pied: (Autosomal recessive). Splotches of white feathering are present on the bird, sometimes so much so that the birds' characteristic markings are completely whited-out. Some birds are so heavily pied that they appear all-white with absolutely no markings, not even the teardrop; these birds are known as fully-pied whites. Pied can be combined with any other mutation.

White: (Autosomal recessive). Both cock and hen are completely white (no markings, not even teardrops), sometimes with some minor grey or fawn flecking on the head and back of the bird. The way to tell the difference between the sexes is by the color of the beak: cocks have the red beak, hens have the orange beak. Prolific breeders.

Fawn: (Sex-linked recessive). Everything which is normally grey on the bird becomes a light brown color. Markings remain intact, but black coloration is replaced with dark brown. Eye coloration is reddish brown and helps to distinguish fawn hatchlings from grey ones in the nest. Fawn can be combined with many other mutations, including pied, black breasted, black cheek, penguin, and more. Prolific breeders.

Chestnut Flanked White (CFW): (Sex-linked recessive). Both cock and hen are an all-over ivory white color, but the cock and hen retain their respective markings (even the tear drop is intact). Usually the cock's cheek patches, breast bar, and flanking are slightly diluted and seem paler in comparison to the markings on a normal bird. Fawn-series CFWs are referred to as "Continental CFWs" and have a cream cast; grey-series CFWs are called "English CFWs" and are more pure white in color. Occasional out-crossing of CFWs to well marked grey birds may help improve the intensity of the CFW's coloration. Prolific breeders. Note that CFW is in an allelic series with the Lightback gene.

Recessive Silver (in grey-series birds); Recessive Cream (in fawn-series birds): (Autosomal recessive). Silver: The normally grey body of the bird appears dark silver, being lighter in body coloration than a normal bird. The markings all remain intact and as vibrant as on a normal bird. Cream: Pale cream (diluted fawn) body color; again, the markings remain intact and vibrant.

Dominant Silver (Silver Pastel, Dominant Dilute Grey) if in grey-series birds, Dominant Cream (Cream Pastel, Dominant Dilute Fawn) if in fawn-series birds: (Autosomal dominant). Silver birds (grey-series): Bluish-silver body, similar to recessive silver except that the cock's cheek patches and flanking are cream in color, not orange. Cream birds (fawn-series): Pale cream (diluted fawn) body color where the cheek patches and flanking on the cock are a creamy-fawn color. Potentially has a lethal factor in the double-factor form. Outcrossing with recessive silver or recessive cream may improve coloration.

Penguin: (Autosomal recessive). The top of the head, back and wings are the normal body color (laced or edged with a silver lining to edges of wing and tail feathers), but the underparts (sides of body, breast, and belly) are all bright white--the cock has no breast bar or teardrop but retains flanking and cheek patches. The hen has white cheeks in addition to the white breast and belly and no tear drops. Tail barring is diluted. Penguin can occur in combination with other mutations (silver penguin, fawn penguin, black cheeked penguin--which has white cheeks, etc.). Occasional out-crossing to normal greys or fawns can improve the intensity of the penguin's coloration. Prolific breeders.

Lightback: (Sex-linked, recessive to normal but dominant to CFW*). Light grey body (distinct from 'silver') with diluted cheek patches and flanking on male, while retaining deep black breast bar and tear drops. Underparts bright white. Can be combined with a number of other mutations for interesting results, including black-cheeked, silver, blackbreasted, etc. (Combination of this gene with other sex-linked traits, e.g. Fawn Lightback, requires the phenomenon of crossing over to occur, so is not guaranteed). *Note that Lightback is in an allelic series with the CFW gene.

Crested: (Autosomal dominant). Birds have a rosette of feathers atop the center of the head, the feathers sticking almost straight up, and growing in different directions. Does not appear to cause a lethal condition in the double-factor form as in canaries. Can occur in combination with any other mutation.

Yellow-beak: (Autosomal recessive). Both cocks and hens have a pale yellow beak instead of a red or orange beak. Can occur in combination with any mutation, but looks particularly attractive when combined with a dark-bodied bird to create contrast.

Black-cheeked: (Autosomal recessive). The cock's normally orange cheeks are completely black in color, and the flanking is a much deeper brown-black. Strangely enough, then hen of this mutation also sports black cheek patches, but she does not have a breast bar or flanking. Black-cheeked young also fledge with black cheek patches. This mutation can be combined with many others with interesting effects. Prolific breeders.

Grey Cheeked (if on grey-series bird) or Fawn Cheeked (if on fawn-series bird): (Autosomal dominant). Silvery-white to cream body with rich buff underparts. Black breast bar and tear marks are present. The cheeks, however, are not orange but range from orangish-fawn to grey. Cheek patches can also be half-orange & half-grey. Both sexes have cheek patches, but the hens do not have breast bar or flanking. The best coloration is achieved by breeding a grey cheeked bird to a normal grey (or a fawn-cheeked bird to a fawn); if two grey (or fawn) cheeked birds are bred to each other, offspring may be blind. Prolific breeders.

Orange-Breasted: (Autosomal recessive). Teardrops are absent on both sexes, the once-black breast bar and barring on the cock becomes orange in coloration (especially in fawn-series birds; grey-series birds may retain some black edging), his cheek patches become enlarged, and both the cock and hen's tail coverts are orange and white spotted instead of black and white spotted. Birds which are carrying a single copy of the gene ("splits") may exhibit reduction of the teardrop, slight orange edging to the white bars on the uppertail coverts, and males may have a smattering of orange coloration in the breast bar. Can be combined with other mutations. Prolific breeders.

Black-Breasted: (Autosomal recessive). Enlarged black breast bar sometimes with large, white spotting, enlarged orange cheek patches (sometimes so enlarged that they cover almost the entire head), the white 'spots' on the flanks and tail coverts are elongated, teardrops are absent on both sexes but there is now a prominent black mark adjacent to the beak, the wing and tail feathers often have an orange tinge to them, and the uppertail coverts lack the normal barring but instead are mostly buff with a black shaft. Hens have cream to buff cheeks and throat, the breast is grey or buff, and the belly and rump are buff. Birds which are carrying a single copy of the black-breast gene ("splits") often have uppertail coverts where the white bars are no longer completely separated by black, but rather join together/touch. Additionally, split cocks may also exhibit more prominent cheek patches and breast bar and/or oddly shaped white dots on the flank feathers. May be combined with other mutations. Considered to be prolific breeders.

Black-Faced: (Autosomal dominant). Causes the bird to appear melanistic: the normally white area between the beak and teardrop is black in cocks (& grey in hens), and the cock's breast bar continues down past the chest onto the belly, ideally all the way down to the vent so that the entire belly is black. Hens have grey extending past the chest and down the belly instead of black. Can be combined with other mutations. May be moderately challenging to breed.

Florida Fancy: (Autosomal co-dominant). When "double factor" the bird lacks all black pigment and has bright white to off-white body color with rich buff-colored underparts. Cock's breast bar is absent and neither hen nor cock have teardrops or black barring in the tail. Cocks retain cheek patches and flanking. When "single factor" (called the "Florida Silver") birds are silver or pale grey overall and black markings (breast bar in males, teardrops and tail bars in both sexes) become dark grey. May be combined with several other mutations. Prolific breeders.

Isabel: (Autosomal recessive). European mutation that is identical in appearance to the double-factor Florida Fancy, but which has a different mode of inheritance (recessive) and therefore is only seen in the "double-factor" bird.

Eumo: (Autosomal recessive). Dark grey bird with black vent and rump; the space between the beak and teardrop is also black. Additionally, the cock's orange cheek patch is mostly or entirely missing (replaced by grey); the area from the chin to the vent is largely black; tail coverts and flanks are partially or completely lacking white dots. Eumos have a feather abnormality (the wing feather barbs do not interlock) which gives them a frizzled appearance and prevents them from flying well; they are best suited to smaller enclosures for this reason. Newly fledged chicks also require additional low-placed perches in the enclosure and are susceptible to chills. Eumo chicks can be identified in the nest 5-7 days after hatching by the color of the feather tracks on the belly (dark grey in eumos, buff in normals); they are also very darkly colored upon fledging and have frizzled feathers. Eumo is a recessive gene, but split-to-Eumo chicks have a darker grey face upon fledging which fades as they mature; they can therefore be identified as splits upon fledging but at no other time.
