This mutation was first identified in both Australia and England at the same time in 1934, though populations in both regions had existed for years beforehand. In fact, one of the Australian breeders developing Cinnamon would go on to develop Opaline. Cinnamon budgies have slightly paler body color and brown-colored markings that would otherwise be black, even in blue budgies. This decrease in melanin also exists in the eyes of nestlings, resulting in chicks with plum-colored eyes that darken by the time they fledge. When Cinnamon is combined with Lutino, a lacewing is produced (see lutino for more).
