mLine 91:
Line 91: − In water and temporarily wet habitats storks are bound to very different degrees. Thus the yellow-bill and the open-bills life are found near the shore, while the marabou and Abdim's stork often stay far away from water in the open savannah. However, most species live at least near swamps, lakes or riverbanks.+ − + + + + + + + + + + + + +

Storks are found on all continents except Antarctica. They are common in large parts of Eurasia, Africa, Australia and South America; in North America, on the other hand, they inhabit only the extreme south. Most species are native to the tropics; only three species live in the temperate zones.

They generally live in wetlands and feed mainly on fish, frogs, small reptiles, crustaceans and molluscs, insects and small mammals. The yellow-bill and the openbills are found near the shore, while the marabou and Abdim's stork often stay far away from water in the open savannah. However, most species live at least near swamps, lakes or riverbanks.
Because the white stork migration is so famous, it may come as a surprise that most storks are not migratory birds. They stay close to their breeding grounds and move around relatively small-scale outside the breeding season. In contrast, the white stork belongs to the extreme migrators, with representatives of some northern European populations covering some 12,000 miles annually to reach the African winter quarters and return to their breeding grounds. The black stork and Oriental white stork breed in the temperate zone and migrate to tropical regions in winter. With the Abdim's stork, however, a tropical species is also a true migratory bird: it breeds in the steppes and semi-deserts north of the equator and overwinters in the eastern and southern African savannahs.

==Nesting==
==Nesting==
For the most part storks are monogamous; they will mate for life, and return to the same nests every year. However, it has been observed that some storks have changed mates after migrations. Nests are large, up to six feet across and ten feet deep, with new material added every year. Eggs are laid in clutches of two to five, with an incubation period of between 25–35 days. Young reach maturity after four years, and as adults they have a life expectancy of between 30 and 40 years.

Nests are large, up to six feet across and ten feet deep, with new material added every year. Most species nests in colonies, located on trees, in swamps or rarely on rocky walls. Some storks also nest on bell towers, chimneys, and light poles. Eggs are laid in clutches of two to five, with an incubation period of between 25–35 days. Young reach maturity after four years, and as adults they have a life expectancy of between 30 and 40 years.
==Symbolism and folklore==
The stork was a highly respected bird among the ancient peoples. The Egyptians venerated the storks because they believed that they fed their parents who became elders; it was associated with the ''ba'', an image of the soul which migrates every night back to the body in the afterlife<ref>http://www.sheppardsoftware.com/content/animals/animals/birds/stork.htm</ref>. The fact that they also feed on snakes has made both Plutarch<ref>http://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Moralia/Isis_and_Osiris*/E.html</ref> and Pliny the Elder<ref>http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.02.0137%3Abook%3D10%3Achapter%3D31</ref> write that in Thessaly a man could be put to death for killing a stork.
Greek mythology attributes to the Trojan Antigone, daughter of Laomedon and sister of Priam, a legend which had Hera punish Antigone for her pride; the goddess would have turned her hair into snakes that constantly bite her, but she begged for mercy and was turned into a stork instead<ref>http://www.mythindex.com/greek-mythology/A/Antigone.html</ref>. In addition, the good qualities of Antigone, such as love for husband and children, would have moved into the storks, which became a symbol of these virtues. The fables of Aesop also includes the stork; in one, a farmer has caught a flock of cranes intent on stealing his grain, and included among them is an unlucky stork who pleads for his life, but has been judged "by the company you keep" according to the farmer<ref>https://fablesofaesop.com/the-farmer-and-the-stork.html</ref>.
In the Christian tradition there is not much room for the stork, otherwise confused with other waders. It was in the Middle Ages given a comparison to Christ and considered a symbol of filial piety, with the habit of eating snakes also making it an emblem of Christ, who incessantly fights the devil<ref>http://www.whats-your-sign.com/symbolic-meaning-of-the-stork.html</ref>. The stork also appears in numerous noble arms and on the mark of a porcelain factory of the second half of the eighteenth century with headquarters in The Hague, intent on devouring a snake<ref>http://museum.wa.gov.au/maritime-archaeology-db/sites/default/files/hooper_phillips_pottery_porcelain_marks_1894.pdf</ref>.
But the stork as a symbol also had a negative value. In the Bible the stork is considered an unclean bird<ref>https://www.biblegateway.com/passage/?search=Leviticus+11%3A13-19&version=KJV</ref>. To it Saint Jerome, perhaps because of the croaking he emits, associates the ambiguous and/or mocking attitudes<ref>http://www.newadvent.org/fathers/3001125.htm</ref> and even, when it was represented with a fish in the beak (the storks also feed on small fishes), was considered the emblem of the devil who takes a soul from God.
===The stork and babies===
The stork is notoriously mentioned today and through much of history as a metaphor for the birth of children, either by a glance at a woman who becomes pregnant as a result, or in the famous deliveries in which these flying birds have a baby slung in a sack hanging from their beaks<ref>https://www.youtube.com/watch?v=dODSHuvuoTM</ref>. There are several versions, not very dissimilar to each other, to explain the belief that lies at the origin. One, native to Northern Europe, is given by its symbolic link to the Great Mother; the other, always connected to the aforementioned primordial deity, derives from the nature of the stork that "would fish" the life in the waters of the womb Great Mother; while a third is provided by the writer and linguist Angelo de Gubernatis, who explains the Germanic popular belief that storks would fish newborns in a fountain, with the fact that this bird lives in watery areas and therefore rainy: the newborn would thus represent the new sun rising from the clouds after long days of rain<ref>https://www.gutenberg.org/files/38688/38688-h/38688-h.htm</ref>. Another interpretation is that the belief stems from the fact that the storks build the nest on hot spots such as the chimneys and at the time of the legend the only houses that had the fireplace always on were those where there was a newborn<ref>https://blog.sfgate.com/pets/2011/05/08/where-did-the-delivery-stork-myth-originate/</ref>.
