Notably Small as compared to the body size.
Beak and beak settings: 20%
Conical in shape. The narrow tip of the cone represent the beak. No downward inclination at all as it is the case with other Bolks. There is no gap or dip between the frontal and the beak
They appear of darker in color than the shields because of the feather density in this area. They should be long, wide, round and a mirror image and far from each other. The cheeks extend themselves upward from each side covering ¾ of the eye as they reach the frontal. There should be a dividing white line (Messala) crossing the frontal separating the dark feathers of the cheeks and that's common among all the bolks.
Should be small, smooth, white and free from any coarsens.
Exceptionally wide, occupying more than half of the head. its periphery stretches towards the top of the skull giving it a characteristic look among all the Bolks. While examining the bird at a close up the periphery of the Iris should reveal the vascular net of the rich blood vessels as the eye is slightly move from one direction to another. This is more pronounced than the Walnut groups. The iris color reflects the yellow shield color with some pigmentation. The eyelid is thin, smooth and white.
Neck: 5% .
The back of the neck is thick because of a heavy amount of fluffed feathers in that area as it is the case in most of the male Bolks. The neck is short and wide as viewed side ways.
Flights and tail: 5%
Wing tips must be shorter than the tail and close to each other. Flights in many of these birds display themselves just below the tail but not dragging permanently on the floor. The flights or the first 10 primary feathers are white. Bolks express a minimum of 12 tail feathers and notable thick tail coverts.
Legs and feet: 5%
Legs strong and short, free from feathers below the hock. Toes are large and well spread apart.
Tight long sloped body. The back is broad and steep (concave), showing no humps. Their average length is about 12 inches (30 cm) from front of breast to tip of tail. The skeletal structure (frame) is of medium size with an average of 10 ounces (0.6 pound) for a bird.
All birds should be alert with upright position but very low station because of their short legs. The birds tend to set on their hinds (squat) as they become approached in their cage.
The color of the shields should be well defined and masking the entire shoulder and vary from pale to intense yellow color. The rump or the upper tail coverts should be white devoid from yellow feathers.
Loose feathers, which might be evidenced by fluffed feathers or wings dragging permanently on the floor.
Note: if tail or primaries are occasionally interrupted with yellowish feathers, it should be dealt with a minimum distraction on the overall evaluation of the bird.
Disqualification: any obvious cross breeding as indicated by unusual head shape and beak setting or eye color.
