Species: Greater adjutant (Leptoptilos dubius)

Status: Endangered (EN)

Interesting fact: The greater adjutant is named after an adjutant (military officer) because of its stately manner and habit of standing motionless for long periods of time.

With its naked pink head, very thick yellow bill and low-hanging neck pouch, the greater adjutant is a rather eye-catching stork. Colonies of greater adjutants can be seen gathering in India and Cambodia at the start of the dry season in October. Large nests are constructed on tall trees, and eggs are laid between November and January. These hatch after about a month of incubation. Nestlings are cared for until April when the start of the wet season prompts migration north. A carnivore and scavenger, the greater adjutant feeds on a variety of prey, including carrion, fish, reptiles and large insects. It is also known to feed in human rubbish dumps.

Once found across south and southeast Asia, the greater adjutant is now restricted to two small breeding populations. Loss of nesting habitat and feeding sites has had a huge impact as suitable wetland habitats are cleared, drained, polluted and disturbed by humans. Hunting of the adult birds and collection of eggs also threaten the greater adjutant. This species is legally protected in many countries, although enforcement of these laws is often lacking.
