Storks are carnivorous predators, taking a range of reptiles, small mammals, insects, fish, amphibians and other small invertebrates. Storks usually hunt for animals in shallow water. Any plant material consumed is usually by accident. ''Mycteria'' storks are specialists in feeding on aquatic vertebrates, particularly when prey is concentrated by lowering water levels or flooding into shallows. On marine mudflats and mangrove swamps in [[Sumatra]], milky storks feed on [[mudskipper]]s, probing the burrow with the bill and even the whole head into the mud.{{Citation needed|date=April 2021}} The characteristic feeding method involves standing or walking in shallow water and holding the bill submerged in the water. When contact is made with prey the bill reflexively snaps shut in 25 milliseconds, one of the fastest reactions known in any vertebrate. The reaction is able to distinguish between prey items and inanimate objects like branches, although the exact mechanism is unknown.<ref>{{cite journal|last1=Kahl|first1=M. P.|last2=Peacock|first2=L.

Openbills are specialists in freshwater molluscs, particularly apple snails. They feed in small groups,<ref name=":0" /> and sometimes African openbills ride on the backs of hippos while foraging. Having caught a snail it will return to land or at least to the shallows to eat it. The fine tip of the bill of the openbills is used to open the snail, and the saliva has a narcotic effect, which causes the snail to relax and simplifies the process of extraction.<ref name="HBW" />

The other genera of storks are more generalised. ''Ciconia'' storks are very generalised in their diets, and some species including Abdim's stork and marabous will feed in large flocks on swarms of locusts and at wildfires.<ref name="HBW" /><ref>{{cite journal|last1=Dean|first1=G.

''Ephippiorhynchus'' are carnivorous though have a very diverse diet when living on human modified habitats such as agricultural landscapes.<ref>{{Cite journal|last=Sundar|first=K.S.
