The peafowl consist of three species of bird in the genera Pavo and Afropavo of the pheasant family, Phasianidae. They are most notable for the male's extravagant tail, a result of sexual selection, which it displays as part of courtship. The male is called a peacock, the female a peahen. In common English usage, however, "peacock" is used to mean either gender of peafowl. Waimea Valley Botanical Garden, North Shore of O'ahu, Hawai'i
