Three types of peacocks exist -- Indian, green and Congo. Technically, the birds are known as peafowl; peacock refers to the male bird and peahen refers to the female. A peacock typically weighs anywhere from 1 to 6 kg (2 to 13 lbs) and boasts a wingspan of up to 1.57 m (63 inches). Peacocks live for 15 to 20 years.
Indian peacocks, the national bird of that country, live in the forest. Indian peacocks also live in Pakistan and Sri Lanka. Green peacocks, found in southeast Asia, also live in the forest. The peafowl live among deciduous trees such as oaks and maples, along with evergreen trees such as pines and cedars.
Congo peacocks live in central African rainforests. Rainforests grow near the equator, and receive more than 1.5 m (60 inches) of rain annually. Average temperatures range from 20 to 27.8 degrees C (68 to 82 degrees F). Half of the Earth's plant and animal species live in the rainforest.
Many British zoos host Indian peacocks and they are also a feature in the gardens of stately homes. The animals eat plants, insects and flower petals.
