Leptoptilos dubius (Greater Adjutant)

Wikipedia Abstract

The greater adjutant (Leptoptilos dubius) is a member of the stork family, Ciconiidae. Its genus includes the lesser adjutant of Asia and the marabou stork of Africa. Once found widely across southern Asia, mainly in India but extending east to Borneo, the greater adjutant 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.

EDGE Analysis

This tall, incredible bird has an almost prehistoric appearance. Adults can reach heights of 150cm and have enormous wingspans of about 250cm. Its large size and long, wedge-like bill gives it an unmistakable appearance. Mistakenly, people thought this species was good at coexisting with humans because of its ability to scavenge for food in urban areas. However, the wetland and woodland habitat the adjutant requires for breeding has been destroyed and degraded at a rapid rate.
