James I think the point you are making is that similar phenotypes can be created by different mutations. I feel it is wrong to say "that there might not be any...
Good day Terry, You are correct. Thanks for pointing out that what I really mean is that similar phenotypes can be created by different mutations. I mistook...
Thanks for the info on how this mutation may be working, and different effects seen in the budgerigar. Below are some comparison pics of a green Opaline...
Good day Terry, Your info regarding optics is interesting, I will try to get my hands on Andrew Parker's book as this will open new perspectives in looking at...
Karl This Galah mutation illustrates two difficult areas for mutation naming. Firstly it could be equivalent to the fischeri mutation we have just been...
Good day Jaie, Keen observation that the grey might prove to be co-dominant after all! Nice to hear that there are hobbyists like you who works on biological...
Hi Terry, Terry said: Firstly it could be equivalent to the fischeri mutation we have just been discussing. In which case Dark-eyed Yellow would be the...
Hello Dirk, I know my name is not Terry and you don't like to talk to me, but you have asked something, and I would give you an answer (that you have said ...
Judy Excellent comparative photos! This is the type of photo that is required to make really definitive comparisons. Where were the Pied markings in the Pied...
Ken Thanks for that information on how Pied interacts with Opaline in Budgerigars. Clearly there is more going on between these genes than we previously...
Dirk ... I did acknowledged in one message that I was surprised to learn of the long history of this mutation. I have never seen it discussed in English...
Terry- her biggest pied marking is on the top and back of her head. She has a few tiny yellow feathers by her wing joint, but I was afraid couldn't safely...
Terry, Until this discussion was raised, I was happy to ignore the problem of these names. But it is a valid point to raise the conflicting use of DEC and BEC ...
Thanks Terry "Do the splits ever show stray 'pied' feathers?" No the splits show no indication at all and present as normal looking galahs. Nor do mutated...
Strange that this will affect the psittacin distribution. It is the opposite on what we see in normal pied birds. Dirk Van den Abeele MUTAVI, Research & Advice...
Karl said ... This increases it likelihood of being a NSL ino allele rather than a total leucistic like a BEC. The only way to know for certain is to test mate...
Hello, I know a few breeders who have them in America, some who got them in South Afrika, even breeders in Asia, ( most of them are on the “BVA-lovebirds”...
Good Day Terry, I am from the Philippines. The Fischeri DEC mutation is very common here in our country. However, heterozygous combinations with NSL Ino in...
Terry, This DEC mutation is also know in chickens, they call it ‘recessive white’ and as we might suspect this mutation is located on the c-locus (our ...
Judy Thanks for the extra information. It has certainly helped illustrate some previously undocumented features of Pied Opaline combinations. Terry ... From:...
Hello, There are yellow fischeri with dark eyes and blue rumps here in Canada. I have one myself, but I'm not sure if mine is dec (dey) or pastelino. Cindy ......
Good day Cindy, You crossed your bird with ino and if it is a DEC, the resultant offsprings should exhibit an 'evenly colored yellow bird but with a white...
Hello James and Everybody, James, thank you for the tip, but I already knew that. I didn't cross this bird, I bought it as being a yellow fischer. I am not...

We know that a typical black feather is produced when cloudy layer is lost and a heavy melanin concentration is found in the cortex area aside from the medulla...
Roger Do you know how long the mutation has been available in your country? Terry ... From: RVM To: Genetics-Psittacine@yahoogroups.com Sent: Thursday, May 03,...
Terry Sorry have no historical background on the DEC mutation. Roger At 12:26 PM 5/8/2007, you wrote: Roger Do you know how long the mutation has been...
The "Slaty" chicks have feathered more. I'm attaching updated pictures alongside a Blue chick for comparison. The "Slaty" chicks have deep blue, light blue,...
