The Bird on your right is a Heavily Variegated Faun →
When cinnamon is bred with a white ground bird, the cinnamon progeny on white ground are called Fawn. To make things complicated however, there are two types of White bird, being “Dominant” and “Recessive”. How do you tell the difference; the dominant white usually carries just a tinge of yellow on the outer edges of the primary flight feathers (wings). The Recessive white however, shows no yellow at all. With recessive white, a pairing of white to normal can produce normals carrying white, with Dominant white there are no white carriers other than white or faun or blue which are all white ground. The majority of whites found in Australia are Dominant, with this in mind all the comments below refer to Dominant White. Pairing two dominant white ground birds together will result on average of 25% of the young dying. This is because the dominant white gene is lethal when it is present on both sides of a pairing. Also because a fawn has the dominant white gene this same principle applies. A youngster produced from a dominant white ground bird but does not show to be of a white ground but is normal in appearance will not carry the lethal gene because it is not sex linked like the cinnamon gene. Below are some examples of pairings with dominant white ground birds, which may produce fawns, and some pairings of fawns and the young they may produce. Note a “Blue” is a white ground bird with the dark melanin over, rather than the light or Cinnamon melanin over which is the Faun.
When pairing, type should be the first consideration because the use of cinnamon over time, without considering type will lead to loss of type and very fine-feathered birds. The following is a combination of pairs and the expected chicks produced.
