What characterizes the bare skin covering the head and upper neck of the male during display periods?

Answer

It presents a vivid palette of blue and orange or red caruncles.

The bare skin covering the head and the upper portion of the neck in the male Ocellated Turkey is highly distinctive, particularly when compared to the female. This skin displays vivid coloration, featuring patches known as caruncles. These caruncles exhibit striking hues of blue, orange, or red. The intensity of this coloration is dynamic; the skin can become significantly more colorful and pronounced during the breeding periods as part of the mating rituals intended to attract females.
