Elegant Goldfinch – Yellow Agate with a White Head

Description:

This mutation is a combination of the sex-linked, recessive Agate factor with the autosomal recessive white-headed factor and the autosomal dominant yellow factor. It is a far cry from the wild-type phenotype, and the reddish-orange mask extends down the bird’s neck and cheeks. An interesting mutation from a scientific point of view. Whether you like it or not, it is now something that must be taken into account!
