Scientifically known as Argusianus argus, the Great Argus, is seen as a brown-plumaged pheasant with a small blue head and neck, rufous red upper breast, black hair-like feathers on crown and nape, and red legs. Interestingly, the male has been found to be among the largest of all pheasants. The male measures 160–200 cm in total length, including a tail of 105–143 cm, and weighs 2.04–2.72 kg. The female, on the other hand measures 72–76 cm in total length, including a tail of 30–36 cm (12–14 in), and weighs 1.59–1.7 kg. It’s been realized that the young males attain adult plumage in their third year.

These birds happen to be one of the most unusual of all bird species. The males are easily identified with massive primary, secondary and tail feathers. It has a blue face, a black crown and a distinctive short crest. It has brown upperparts finely mottled with buff. There are also iridescent ocelli that can be found on the wings and tail. Interestingly, research shows the wings can continue to grow until the bird reaches its sixth year. The females possess similar features, but are smaller than males. Furthermore, they lack the ornate tail and wings.

The Argus is undoubtedly calm and gentle. Despite their great personalities, these birds are not difficult to keep or raise. Due to their large size, they need heat in the winter. They are, therefore, expensive to keep in the north. These birds need a large and varied diet. On their list of delicacies can be found apples, oranges, raisins, raw peanuts, meal worms, turkey pellets and greens. The females make excellent mothers, and are found to be smaller and duller than male, with shorter tails and less ocelli. Furthermore, they tend to produce two to four eggs a year.
