The distinctive feature of the order Passeriformes is the arrangement of the three toes, two forwards and one backwards. This particular characteristic allows perching, which is why Passeriformes are also known as perching birds [12]. The Paradisaeidae family is best known for its sexual dimorphism and elaborate male physical traits. Some of the physical traits include exotic feathers of various shapes, colors and sizes. Additionally, the family is known for extravagant courtship rituals performed to achieve reproductive success. The Paradisaeidae family is found primarily in the rainforest of New Guinea. (Wikipedia, [16]). The genus Lophorina which contains only the species Lophorina superba is known for the sexually dimorphic distinction between the sexes. In particular, the male of Lophorina superba has jet black feathers and a neon greenish blue breast is presented to the female during courtship. The male projects his feathers creating an oval shield, almost creating an illusion to persuade the female sex. As a result of female selectivity, male physical traits evolved through sexual selection, leaving the female sex unchanged with no extravagant characteristics. Unlike the male, the female has a gray and brown basic color (Wikipedia, [17]). [3, 12, 16,
