This interesting melanistic mutation was first discovered by Venezuelan breeder Mr. Edixon Laya in 2002 when he found several mutant birds by chance at a house visit. After purchasing them and attempting to develop the mutation, he passed them off to Alejandro Álvarez, a star breeder known for his champion birds. Álvarez was able to
Crested is a mutation that alters the direction that certain feathers grow on the head. Despite being around for nearly 100 years, first popping up in many Australian aviaries in the late 1920s, understanding of their genetics is not absolutely certain. Many theories attempt to explain the odd half-dominant half-recessive behavior of the mutation, a
This dominant mutation was developed around 2013 by G. Kerle in Australia. The bird in its SF form has a bright yellow face, white forehead, and seagreen body color (pictured first). It’s for this reason that SFs are sometimes called “whitecap seafoams”. The DF form, however, has a mostly lime green and light aqua body
A dominant mutation very similar to Goldenface, but with stronger coloring and healthier genes. They are most easily identified at the juvenile stage; DF Goldenfaces have pale yellow faces, while Goldentops have a similar shade to the adults. Their SF and DF forms differ in the same ways Goldenface does, with SF forms having yellow
Texas Clearbodies are one of the three original clearbody mutations developed in the 1950s, specifically in Texas. They are the most widespread of the remaining two, but still difficult to obtain. Their green body color is very faint but still visible towards the lower chest. The best identifiers of this mutation over the Easley Clearbody
One of the three clearbody mutations, it was developed and named after American breeder G. Terraneo in 1954. The mutation was sex-linked, lightened body color, and had opaline-like markings with green or blue body color. It was so similar to Opaline that some believed it to be an allele on the same gene as Opaline.
One of the three original clearbody mutations, the Easley Clearbody was discovered in 1954 by C. F. Easley. They are the least common of the remaining two, and the only one with dominant inheritance. Modern-day Easley Clearbodies have a minimum of 50% body color dilution, gray cheek marks, and black flight feathers (the latter being
One of the three fallow budgie mutations, German Fallow was discovered in 1932 just two years after the first fallow in Australia. Birds with German Fallow have ruby-red eyes slightly darker than a Lutino’s, with white iris rings, cinnamon-like markings, an orange beak, and mostly removed body color. The male’s cere color remains pink or
One of the three fallow budgie mutations, English Fallow was discovered in 1937 by beginner breeder F. Dervan. They have fully ruby-red eyes, as well as cinnamon-like markings, an orange beak, and different amounts of removed body color that vary from bird to bird. The male’s cere color remains pink or faded purple, even at
The least common of the three fallow budgie mutations, Scottish Fallow was discovered in the 1960s and thought to be an English Fallow until test breeds proved otherwise. They have bright red eyes with a pink iris ring, as well as cinnamon-like markings, an orange beak, and mostly removed body color. The male’s cere color
