I have heard of mosaic canaries before, but have never known exactly what they are.
Could someone please enlighten me?

Reason being, among this years canaries are a few birds which are partly white and partly yellow in their ground colour. I had always understood normal marked canaries to be the canary equivalent of pieds, with random distribution of 'normal' colour on a consistent ground colour, which is usually yellow but can be white or red in mutations/hybrids.
I haven't come across this randomly variable ground colour before.

I'll pop out and get a photo presently to speak the proverbial thousand words.

Thanks in advance,

Mosaic canaries are obviously those covered in broken pieces of ceramic tiles.

But seriously folks, after consulting google images I reckon they are mosaic. I will get a picture, presently....

they are my fav canary .... mosiac refers to the pattern as it resembles mosaic .

If you haven't already googled.

Isn't this the same as dimorphic?

They are the same. The non-intensive dimorphic is referred to as a mosaic. The intensive dimorphic is extremely rare and is known as a "check frost" which has a completely different pattern. Dimorphics first appeared in the 1920s from Red Siskin x Canary crosses.

Genetically a mosiac at birth is one which contains the DNA material from two zygotes, sometimes the result of twins fusing together at first cell division, but more commonly the result of an error during meiosis resulting in egg or sperm with two genotypes. The result is a bird which has two sets of cells exhibiting each genotype in its phenotype.

Mosaicsism also occurs during normal cell division as a result of mutation, particularly as the body ages. Technically most older humans are therefore mosaic and most leukemias and lymphomas are the result of spontaneous human mosaicism.

Well you live and you learn . .

It took me 12 years to learn that I had been a biped all of my life . .

And over 70 years to find out that sometime in the future I will become a mosaic biped




Is there a self-help group for such people?

I think it is called a moped club...
