Parblue Yellowface Fischeri Lovebird

To observe the differences between parblue and parblue yellowface, you need to look at two things, the first being the mask.

After the yellowface lovebird mutation was discovered, breeders immediately began various crossbreeding projects tailored to their own imaginations and goals. Each breeder has a unique vision in developing new bloodlines, whether to increase color variation, strengthen certain genetic traits, or create previously unimagined combinations of aesthetic mutations.

This process involves meticulous genetic analysis, observation of trait inheritance patterns in yellowface fischeri, repeated experiments, and, of course, the breeder's experience plays a crucial role in ensuring the desired results are achieved.

With a spirit of innovation, breeders strive to integrate the beauty of the yellowface mutation into potentially endless combinations of mutations, while adhering to existing standards and prioritizing the overall health and quality of the birds. No matter how beautiful the color of a lovebird may be, it will be meaningless if the size standards and body shape criteria fall far below what has been agreed upon.

Today, breeders have achieved an extraordinary milestone by successfully combining the parblue and yellowface mutations, resulting in a generation with the temporary name parblue yellowface. This is a cross that was previously difficult to imagine.

How could a combination of partial psittacine reduction (PPR) mutations be achieved, resulting in an intermediate color that is certainly different from both parents? The existence of this parblue yellowface combination also breaks the previous assumption that the yellowface/Orangeface fischeri mutation can only be enjoyed in the green series. They will not appear phenotypically in blue and blue1blue2. However, in reality, a very special combination of parblue yellowface has now emerged.

Characteristics of Fischeri Parblue Yellowface

There are not many significant changes between parblue and parblue yellowface, as they are still within the PPR corridor. However, there are several important points that distinguish the two, which I will explain in this article. This is important because some individuals have been found selling parblue birds with a more yellow phenotype than the standard, labeling them as parblue yellowface, which is clearly different both phenotypically and genotypically. Therefore, you need to pay attention to the following fundamental differences.

Forehead: brilliant Yellow.
Crown: grey on light yellow background, lighter in colour towards the nape.
Cheeks:yellow light orange with grey transition zone towards the yellow neck. This transition zone runs downwards at the center of the eye.
Chin, throat and upper breast: yellow light white.
Eyes: dark brown with unfeathered white eye-ring.
Beak: Yellow. Lower chest, flanks, belly and anal region: green.
Mantle and wing feathers: a shade darker than the rest of the body.
Primary flight feathers: green outer flag and blue-black inner flag.
Wing bends:yellow.
Rump and upper tail coverts: violet.
Under tail coverts: green.
Tail feathers: the tail feathers are predominantly green with a blue tip. The secondary tail feathers have a brilliant yellow spot drawing in the middle. This spot drawing is partially surrounded by a black zone.
Legs: grey.
Nails: a shade darker grey than the feet.

Color differences between parblue and parblue yellowface masks

To observe the differences between parblue and parblue yellowface, you need to look at two things, the first being the mask. Although both are still within the “yellow” color range, there are differences in color intensity and depth. In parblue or blue1blue2, the forehead color tends to be darker, leaning toward mustard yellow or bright orange, then turning cream on the cheek area down to the chest, forming a smooth gradation.

Meanwhile, in parblue yellowface, the forehead color is a brilliant yellow, almost fluorescent, and the cheek and chest areas also appear brighter compared to parblue/blue1blue2, even though they are both within the cream color range. This is due to the absence of red psittacine in the base version (green face yellow), so when combined with PPR, it becomes even brighter.

Beak color differences between parblue and parblue yellowface

The next difference that can be observed between parblue and parblue yellowface is in the color of their beaks. We all know that the beak color of parblue/blue1blue2 is orange or light orange, especially in adult birds. This is the effect of the reduction of red color (green series) to one or two steps below it.

Meanwhile, the parblue yellowface has a pink haze beak color. In adult birds, it is more similar to the beak color of the blue1 mutation with a distinctive yellowface yellow accent on the front of the beak. Young parblue yellowface birds tend to have a more yellowish beak color. This is more akin to the original beak color of yellowface, which is fully yellow, then reduced by the PPR allele to resemble the beak color (blue series) with residual yellow accents, particularly at the front tip.

This article discusses the characteristics of the parblue yellowface or yellowface blue1blue2 mutation combination. We hope the information provided in this article serves as a useful reference for those interested in understanding this mutation more deeply and developing it further in the future.
