Ocellated turkeys are similar in appearance to North American wild turkeys (Meleagris gallopavo), but are lighter in weight and more brilliantly colored. Males weigh about 4.5 kg and are roughly 0.9 m in length. Females weigh about 2.7 kg.
The body feathers of ocellated turkeys are an iridescent bronze-green color, with those of the male being brighter than the female. The tail feathers are bluish-gray with blue-bronze eye spots on the ends, which give this bird its name, as oculus is Latin for eye. The tail feathers also have a bright gold tip.
The skin of the head and neck lacks feathers, is bright blue, and is scattered with orange-red nodules or "warts". Around the eye is a bright red ring of skin. Males have a blue fleshy crown on their heads with yellow-orange warts. During the breeding season, the crown enlarges and the eye-ring and warts become more visible in males. Legs are a dark red color in both sexes, but adult males have spurs measuring around 3.8 cm in length.
