Taxonomy

Description

Leptoptilos javanicus is a very large stork measuring between 114 cm and 129 cm in length. It is commonly known as lesser adjutant and can be identified by its naked head, yellowish orange neck and hunched appearance. The upperparts of this stork are dark grey-black with dark underwings, while the underparts are white. The wedge-shaped bill is massive and yellowish with light corrugations on the base of its mandible. The breeding males show sexual dimorphism, in which they show coppery magenta spots on their wing coverts, small white triangular patch at the base of wings and redder head sides (IUCN, 2017). For the juveniles, the head and neck have more feather and their upperparts are less glossy. Usually, the lesser adjutant is solitary or in small loose groups and its main diet includes molluscs, fishes and crustaceans (Strange & Jeyarajasingam, 1993). Lesser adjutant can be found in South-East Asia and is restricted to mangrove habitats. It is listed as vulnerable under the IUCN Red List due to habitat loss and hunting pressure.
