The greater adjutant was once found widely across southern Asia, mainly in India but extending east to Borneo. It is now restricted to a much smaller range with only two small breeding populations; one in India with the largest colony in Assam and the other in Cambodia. Populations disperse after the breeding season. This large stork has a massive wedge-shaped bill, a bare head and a distinctive neck pouch. During the day, they soar in thermals along with vultures with whom they share the habit of scavenging. They feed mainly on carrion and offal; however, they are opportunistic and will sometimes prey on vertebrates.
