Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Lesser Adjutant faces severe pressure from wetland habitat destruction across Southeast Asia, with rice paddies, fish ponds, and urban development replacing critical feeding areas. Disturbance at colonial nesting sites has led to breeding failures, while pollution and overfishing have reduced prey availability in remaining wetlands. The species' dependence on large, undisturbed trees for nesting makes it particularly vulnerable to deforestation and human encroachment.

Threat summary

Habitat

Lesser Adjutants inhabit freshwater wetlands, rice paddies, fish ponds, and shallow lakes across Southeast Asia, requiring large emergent trees for colonial nesting. They prefer open wetland areas with abundant fish populations and minimal human disturbance for feeding.
