About These Birds
African Openbill
72–90 cm. All-black plumage with gloss; distinctive large bill with a gap between mandibles adapted for extracting apple snails. Resident across sub-Saharan Africa and Madagascar in wetlands, rivers, and rice paddies. Feeds almost exclusively on molluscs. Colonial breeder in trees near water.
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.
