When I was a lot younger than I am today, we had semi-tame peacocks that lived in our neighborhood. They would perch on our roof, right outside my bedroom window, and screech loudly in the early morning. They are beautiful birds but very loud. These particular birds are generally known as "peafowl." Here is an explanation from the Wikipedia article on Peafowl.
The peafowl include three species of birds in the genera Pavo and Afropavo of the Phasianidae family, the pheasants and their allies. There are two Asiatic species (the blue or Indian peafowl originally of India and Sri Lanka and the green peafowl of Myanmar, Indochina, and Java) and one African species (the Congo peafowl native only to the Congo Basin). Male peafowl are known for their piercing call and their extravagant plumage. The latter is especially prominent in the Asiatic species, who have an eye-spotted "tail" or "train" of covert feathers which they display as part of a courtship ritual. The term peacock is properly reserved for the male; the female is known as a peahen, and the immature offspring are sometimes called peachicks.Here is an interesting discussing how the peacocks attract females with their tail feathers.
See "Biomechanics of the Peacock’s Display: How Feather Structure and Resonance Influence Multimodal Signaling." There is also a video showing courtship displays.
