Pied (Not yet characterised heredity)

Sporadically and in line breeding pied Lineolated Parakeets appeared. The variegation usually is restricted to the head and asymmetric (Ehlenbröker 1994). Bauer (1990) reported, that in his breeding every time pied offspring occurred from one green couple. He is quite sure, that this mutation is sex-linked, because all pied birds were female.
Sometimes also the beak and/or claws are pied. Some pied cocks are split to ino as well.
According to my past investigations one can just set speculations concerning the heredity. Also it seems, that there are still problems establishing that mutation. For example, one couple (both pied, cock split to ino) every now and then raised chicks, both red eyed and black eyed, which nearly never got older than 2 weeks. So they reared just one chick until now, a green cock.
There's also the possibilty that the sporadically occuring pied areas are no result of a mutation but a modification. Then all attempts to breed pied birds would be in vain because modifications cannot be inherited. A hint for this thesis is that sometimes one couple of Lineolated Parakeets raise pied chicks, even in different clutches, but that these birds don't raise offspring themselves, for various reasons: the pied birds die before getting mature, the clutches of paired pied birds are sterile or none of the chicks of fertile clutches shows any pied areas and doesn't inherit it (known from test-crossings).
Nearly at the same time two white-blue pied Lineolated Parakeets appeared. One bird, a cobalt-creamino pied female, was raised by a cobalt male (split to ino) and a cobalt female. The pied areas of that female span the whole body. Even single feathers are blue as well as white.

The second Lineolated Parakeet with pied areas hatched in 2004. The colours of parents are turquoise (male) and creamino + 1 dark factor (female). The gender determination of that birds was done by DNA testing and showed that it is a male. The colours, which can be found in the plumage of this pied bird, are specified as a mixture of turquoise, cobalt, creamino and violet factor. The eyes were red in the first week, like it can be observed at inos. They darkened by and by and are ruby coloured now. Apart from that male the pair also had a turquoise female and four cobalt males in that clutch. These information originate from the
Catharinaparkieten Studie Groep. There you can find pictures of the pied birds as well, directly available via that link.

We have to wait and see if the pied mutation in these Lineolated Parakeets can be established.

Here you can find further examples of pied Lineolated Parakeets:

Another very interesting example for a possible pied Lineolated Parakeet is that bird, which was reared by two green birds last year. The parents both don't have any recessive factors. Two further chicks, which have been raised by that couple, are both green cocks. The mortality rate of the chicks of that couple is extraordinary high, so usually just one chick reached the youth moult. The others either died already in the egg or aged 3 to 7 days.
The symmetrically occurring yellow spots in the plumage were especially distinct at the just feathered chick. The toes and the beak showed spots as well. Even after the youth moult a obvious yellow "colouring" of the plumage is visible.

After youth moult - one can see the pied areas on the primaries quite well.

According to so many open questions, which that possible mutation offers, I would be glad to get further reports (concerning the breeding of pied Lineolated Parakeets) and photos! Please contact me simply via the contact form.
Thanks a lot for your assistance!
