Mayilattam, a dance of South India, is also called:

The correct answer is Peacock dance. Mayilattam (from "mayil", meaning peacock, and "attam", meaning dance) is a folk dance of Tamil Nadu and Kerala, in which the dancers dress as peacocks and imitate the graceful movements of the bird. It is usually performed in the temples of Tamil Nadu, especially during the festivals of Lord Murugan, whose vehicle (vahana) is the peacock.

In Mayilattam, the dancers, often young women or girls, wear a costume that makes them look like a peacock, with a headdress shaped like a peacock's head and beak, and a large tail made of peacock feathers, which can be opened and closed using a thread. They imitate the movements of a peacock, such as walking, pecking, turning the head and, most beautifully, spreading out the tail feathers in a fan. Sometimes, the dancers stand on tall wooden stilts tied to their legs, which makes the performance even more challenging. The dance is accompanied by the music of the nadaswaram (a wind instrument) and the thavil (a drum), and by songs in praise of Lord Murugan. The dance is believed to please Murugan and bring his blessings.

Tamil Nadu has many folk dances that use costumes of animals and birds. Poikkal Kuthirai Attam is the dummy horse dance, in which the dancer wears a horse costume made of light materials. Kaalai Attam is the bull dance, and Karadi Attam is the bear dance. Other folk dances of Tamil Nadu include Karagattam (balancing a decorated pot), Kummi (women dancing in a circle while clapping), Kavadi Attam (in honour of Murugan), Oyilattam and Kolattam.
