The distinctiveness of the “Intensive” mutation

The Intensive mutation display some absolutely unique aspects, never encountered in any other species. Before going into the mutation description we should tell something about the original wild-type bird.

Canary (Serinus canaria), originating from the Canary Islands, the Azores and Madeira, bears a green plumage because of the presence of black and brown melanins and of lipochromes, namely yellow carotenoids.

We will focus our attention on the aspect so called category, that is the distribution of carotenoids and the plumage structure.
