The green peafowl (Pavo muticus) (from Latin Pavo, peafowl; muticus, Mute, docked or curtailed) is a species of peafowl that is found in the tropical forests of Southeast Asia. It is also known as the Java peafowl, but this term is properly used to describe the nominate subspecies endemic to the island of Java. It is the closest relative of the Indian peafowl or blue peafowl (Pavo cristatus), which is mostly found on the Indian subcontinent.
The green peafowl was widely distributed in Southeast Asia in the past from eastern and north-eastern India, northern Myanmar and southern China, extending through Laos, and Thailand into Vietnam, Cambodia, Peninsular Malaysia and the islands of Java. Records from northeastern India have been questioned and old records are possibly of feral birds. The ranges have reduced with habitat destruction and hunting.
Green peafowls are found in a wide range of habitats including primary and secondary forest, both tropical and subtropical, as well as evergreen and deciduous. They may also be found amongst bamboo, on grasslands, savannas, scrub and farmland edge. In Vietnam, the preferred habitat was found to be dry deciduous forest close to water and away from human disturbance. Proximity to water appears to be an important factor. source
