About These Birds
Lesser Adjutant
110–120 cm. Naked red-yellow head with white ruff; large pale bill. Resident across South and Southeast Asia in wetlands, mangroves, and agricultural areas. Vulnerable; declining due to habitat loss and hunting. Feeds on fish, frogs, and carrion; nests colonially in trees.
Oriental Stork
The oriental stork is one of the most endangered stork species, with fewer than 3,000 individuals remaining in the wild. It was once widespread across East Asia but declined dramatically due to wetland drainage and pesticide use. Reintroduction programs in Japan and Korea have achieved notable success.
