Cheek

The first zebrafinch presented at the exhibition were far from those we now have in our farms. They were rather filiform and small in all respects resembling the majority of the birds that we currently find at the pet store on the corner.

The evolution does not know made in a day but it has been relatively fast. Here we will talk about the grey zebrafinch, all simply because it is my specialty, and I am starting to know it well.
We can observe that the greys, which are a classic (We call «classic» the greys and the basic mutations that are the brown, pale back and masked.), presented in the major exhibitions is no longer very far from the perfect grey. The type and size are for the most part excellent level and the difference is mainly on the color.

1. The main defects of grey males

In recent years many defects have appeared in the gray we have the leisure to see in our exhibitions. I’m going to introduce a few of them that I think are most commonly encountered on display or on our farms.

a) The stripes behind the cheeks



For the last couple of years, at least from what I’ve personally noticed, we’ve been seeing signs of zebra around the cheek. This defect is rather noticeable in black cheek greys, but rather recent in grey males. It is still time to eradicate it from gray strains before it is fully generalized to grey zebrafinch.
Because of the similarity to the defect in black cheeks, I do not think it can be equated with a black cheek factor. Indeed, this defect appears even in strains having no affiliation with a strain of black cheeks.

On the other hand, we can think that this phenomenon is due to a high concentration of eumelanin (black), which is sought in gray for a dark back and in black cheeks for an intense black color.

b) Tear spreading in the cheeks

Another defect is the tear, which gives an impression of diffusion in the cheek by the presence of some black feathers in them, and of a line under the eye. Usually in my breeding these are birds that have deep chestnut cheeks. I think we still have it, we can equate it to an excess of eumelanin in this area.
