Storm’s stork is generally solitary, but is occasionally found in small groups (2). This species is thought to feed primarily on fish, but also on frogs, crustaceans, earthworms, invertebrates and aquatic insect larvae (4) (5).
Little is known about the reproductive biology of this species (5). Some form of aerial display occurs during courtship in which pairs do flips in flight, with the lower bird presenting its feet to the upper, or both birds gliding at high altitudes with level wings and legs dangling. Such displays have been observed in March in Sabah (Malaysia) on Borneo (4). Very few nests have been found, but it appears that storm’s stork is a solitary tree-nester (4) (5). In Thailand, chicks have been recorded to hatch in late October (4) (5). Clutches are thought to contain two or more eggs (5), and the chicks are able to fly after around 90 days (2).
