Fischer’s Lovebird Opaline Euwing mutation

The combination of euwing and opaline Fischer’s Lovebird is very interesting because both mutants affect the pigmentation of the wing coverts, each in their own unique way. If we combine this with the typical opaline characteristics, we may get a very special result.

The SL recessive opaline mutation will reorder pigments present in a bird. For example, the orange-red mask of Fischer’s Lovebird Agapornis fischeri will extend to the back of the head, the wing covert feathers will obtain a minimal edged pattern, the rump will become predominantly green and the tail feathers will develop a predominantly orange-red colour.

The autosomal incomplete dominant euwing mutation of Agapornis fischeri will dull the colour of the black eumelanin pigment in the body feathers and on the mantle of SF (single factor) birds. The effect on the pigment is stronger with DF (double factor) birds, and some additional eumelanin even ends up in the feathers of the wing coverts. As a result, both phenotypes give the impression of a darker colour on the wing coverts.
