Black (or dark grey) markings in the Normal budgie mutation (on feathers and head barring) are now warm brown in the Cinnamon. When mixed with opaline mutation - head barring is missing or almost missing.The Cinnamon markings on males are darker than on females. The long tail feathers are lighter than Normal budgies. The body colour and cheek patches appear like half the depth of colour of the Normal mutation. The eyes of the newly-hatched Cinnamon babies are not usual black, but deep plum-like colour.
