Parrotlet colour Mutations.
There is now a vast variety of mutations available in Celestial Parrotlet (Forpus Coelestis) but due to people breeding small mutations to small mutations we have potential to loosing the size and health of the bird. Sensible breeding would be to pair back to a Green or blue with the correct splits to ensure the future health of our Parrotlets. Breeding back to greens or blues maybe the longer way but for our birds welfare it is the best way.
Below are some examples and descriptions of Mutation of celestial Parrotlets available (Some not so readily available).

GREEN / WILDCOLOUR
This is the natural beautiful colour of Celestial/Pacific Parrotlet. Beautiful green mask and grey/olive wash back. The hens lack the deep cobalt sexing markings and their eye streaks are a faint in comparison to the males. It's rare but some hens can have a blue wash to the rump also.

LUTINO
Lutino's are a beautiful bright yellow with red eyes. Males Can be identified by the white in the wings, rump and pales yellow/whitish eye marking down and down the nape. Hens will lack the white in rump and wings (in image)

ALBINO
Albinos are pure white all over with red eyes. Male markings can be seen under a black light, also DNA is evident to Distinguish sex.

AMERICAN YELLOW
A visual yellow Parrotlet dark yellow mask and a pale yellow back, mantle and wing coverts. Males have a washed out blue sex marking and the blue is replaced by white on the hens.

GREEN PIED
A green Dominant pied is a green bird with scattered yellow feathers. Could be a small amount of pied (yellow markings) to heavily pied (many yellow markings) Males retain the blue sexing marks. The only dominate Parrotlet mutation.
Recessive pied, same as a Dominate but a recessive gene so need two birds carrying the gene to produce visually pied offspring.

BLUE PIED
A blue Dominant pied is a blue bird with scattered white
feathers. Could be a small amount of pied (white markings) to heavily pied
(many white markings) Males retain the blue sexing marks. The only

GREEN MARBLED (formally known as Green pastel)
A light green/yellow bird with a marbled ('Lacewing') effect from the nape down the back and throughout the wing. Males have the blue sex markings.

BLUE MARBLED (formally known as Blue pastel)
A sky blue bird with a light blue marbled effect ('lacewing) from the nape, back and throughout the wing. Males have the blue sex markings.

DARK GREEN AND OLIVE
The dark factor effects a completely different part of the feather structure so can be used in combination with other mutations mentioned above ( please do this correctly as doing it genetically unmatched can cause small weak parrotlets).
Dark green is a green with a single dark factor (a denser feather) and an Olive is a green with two dark factors giving off its olive appearance. Dark green is slightly darker than a green. The males retain a darker blue sex markings. In an olive the sex markings are more difficult. The males have a deep olive under wing coverts and the eye streak is also a dark olive.

COBALT AND MAUVE
Again this mutation affects the pigment of the Melanin this effects
the density at the core of the feather.
Cobalt is a blue with a single dark factor and Mauve is a blue with two dark factors giving off its deep dark blue appearance. Cobalt is darker than a blue. The males retain a darker blue sex markings. In a mauve the sexing is more difficult. Only being able to tell the sex by the almost black under wing coverts on the males.

Turquoise
The Turquoise mutation has recently been imported in a good number and spred over a few breeders in the UK and Europe. So in the furture sometime these will be readily avalable and were on display at Forpus International 2015 and also at the stafford show on the Parrotlet Interest Group Stand October 2015.

DOUBLE VISUAL MUTATIONS
We are at the peak of colour mutations within Parrotlets. Now we are getting double, even trebble colour mutations comming through. Here are some exmples.
Bellow left is a Marbled Mauve so this bird is visually carrying the Marbled, and a double factor of the blue gene. The bird on the right is a Marbled Cobalt. So again carrying the Marbled gene but a single dark factor (dark blue or Cobalt) blue gene.
The bird bellow is a Cinnamon Mauve, so visually showing through the Cinnamon, and a double dark factor blue gene (mauve). As this mutation is a 'darker' version of blue Cinnamon it almost gives off a 'chocolate' appearance.
