(Psittacula krameri manillensis)





Ringneck Primary Colour Varieties

Lutino (Ino) Sex-linked recessive
Melanin is substantially eliminated in feathers and body tissue. In the feathers yellow psittacin is revealed in all its glory though the presence of the unaltered cloudy layer, and residual small amounts of melanin, can produce a shimmer of green in certain lights. Yellow is deeper in head and undertail areas and lighter in the flights. The cock's black neckring becomes white but the pink collar, since it is a psittacin pigment, is unaltered.The eyes are red, feet flesh coloured, and nails colourless.
Cinnamon (Isabel) Sex-linked recessive
Melanin black is changed to melanin brown and moderately diluted; as a result body colour is noticeably more yellow.
