''. The bills of storks are large to very large, and vary considerably between the genera. The shape of the bills is linked to the diet of the different species. The large bills of the ''Ciconia'' storks are the least specialised. Larger are the massive and slightly upturned bills of the ''Ephippiorhynchus'' and the jabiru. These have evolved to hunt for fish in shallow water. Larger still are the massive daggers of the two adjutants and marabou (''Leptoptilos''), which are used to feed on carrion and in defence against other scavengers, as well as for taking other prey. The long, ibis-like downcurved bills of the ''Mycteria'' storks have sensitive tips that allow them to detect prey by touch (tactilocation) where cloudy conditions would not allow them to see it. The most specialised bills of any storks are those of the two openbills (''Anastomus.''), which as their name suggested is open in the middle when their bill is closed. These bills have evolved to help openbills feed on their only prey item, aquatic snails. Although it is sometimes reported that storks lack syrinxes and are mute, they do have syrinxes, and are capable of making some sounds, although they do not do so often. The syrinxes of storks are "variably degenerate" however, and the syringeal membranes of some species are found between tracheal rings or cartilage, an unusual arrangement shared with the ovenbirds.

'' openbills, are highly dependent on water and aquatic prey, but many other species are far less dependent on this habitat type, although they will frequently make use of it. Species like the marabou and Abdim's stork will frequently be found foraging in open grasslands of savannah. Preferred habitats include flooded grasslands, light woodland, marshes and paddyfields, wet meadows, river backwaters and ponds. Many species will select shallow pools, particularly when lakes or rivers are drying out, as they concentrate prey and make it harder for prey to escape, or when monsoonal rainfall increases water depth of larger waterbodies. Some species like the woolly-necked storks and lesser adjutant storks have adapted to changing crops of tropical agricultural landscapes showcasing behavioral plasticity that enables them to remain resident despite the transformations brought about by seasonal crops. In South Africa, the woolly-necked storks have adapted to artificial feeding and now largely nest on trees in gardens with swimming pools. Less typical habitats include the dense temperate forests used by European black storks, or the rainforest habitat sought by Storm's stork in South East Asia. They generally avoid marine habitats, with the exception of the lesser adjutant, milky stork and wood stork, all of which forage in mangroves, lagoons and estuarine mudflats. A number of species, especially woolly-necked storks, black-necked storks, Asian openbills and lesser adjutant Storks in south Asia, have adapted to highly modified human habitats, either for foraging or breeding or both. In the absence of persecution several species breed close to people, and species such as the marabou, greater adjutant, and white stork will feed at landfill sites.

Migration and movements

Abdim's Stork (Ciconia abdimii) (7011390701)

Storks vary in their tendency towards migration. Temperate species like the white stork, black stork and Oriental stork undertake long annual migrations in the winter. The routes taken by these species have developed to avoid long distance travel across water, and from Europe this usually means flying across the Straits of Gibraltar or east across the Bosphorus and through Israel and the Sinai. Studies of young birds denied the chance to travel with others of their species have shown that these routes are at least partially learnt, rather than being innate as they are in

migrants. Migrating black storks are split between those that make stopovers on the migration between Europe and their wintering grounds in Africa, and those that don't. The Abdim's stork is another migrant, albeit one that migrates within the tropics. It breeds in northern Africa, from Senegal to the Red Sea, during the wet season, and then migrates to Southern Africa. Many species that aren't regular migrants will still make smaller movements if circumstances require it; others may migrate over part of their range. This can also include regular commutes from nesting sites to feeding areas. Wood storks have been observed feeding from their breeding colony.

Behaviour

Feeding and diet

Storks are carnivorous predators, taking a range of reptiles, small mammals, insects, fish, amphibians and other small invertebrates. 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.

s, probing the burrow with the bill and even the whole head into the mud. 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. Openbills are specialists in freshwater molluscs, particularly apple snails. They feed in small groups, 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. The other genera of storks are more generalised. ''Ciconia'' storks are very generalised in their diets, although Abdim's stork is something of a specialist in feeding in large flocks on swarms of locusts and at wildfires, although other storks will opportunistically feed in this way if the opportunity arises. This is why white storks and Abdim's storks are known as "grasshopper birds". ''Ephippiorhynchus'' are carnivorous though have a very diverse diet when living on human modified habitats such as agricultural landscapes. The foraging method used by the generalists is to stalk or walk across grassland or shallow water, watching for prey.

Breeding

. The jabiru, ''Ephippiorhynchus'' storks and several species of ''Ciconia'' are entirely solitary when breeding. In contrast the ''Mycteria'' storks, Abdim's stork, openbills and ''Leptoptilos'' storks all breed in colonies which can range from a couple of pairs to thousands. Many of these species breed in colonies with other waterbirds, which can include other species of storks, herons and egrets, pelicans, cormorants and ibises. White storks, Oriental storks and Maguari storks are all loosely colonial, and may breed in nests that are within visual range of others of the same species, but have little to do with one another. They also may nest solitarily, and the reasons why they choose to nest together or apart are not understood.
