It is classified by the IUCN as common to abundant but the species is threatened by habitat reduction and poaching.
Feeding
It prefers shallow water where if feeds on small fish, amphibians, molluscs, crustacea, insects and occasionally small mammals.

The red-billed stork usually nests in colonies, sometimes even in towns. Both the male and female construct the nest choosing a high tree, a terrestrial site away from predators, or a small tree over water. Two to four eggs are incubated by both partners and chick rearing is also shared.
Wildfile Specials
- Red-billed storks engage in "Swaying-Twig Grasping": part of the mating display involves the male standing on a potential nest and gently picking up twigs and releasing them while waying its head from side to side.
- Red-biiled storks excrete urine onto their legs in order to cool down. They also regurgitate water for their chicks so they can urinate on their legs and keep cool.
- Parents sometimes help to keep their chicks cool by spreading their wings to provide shade.
