Traditionally, the order Ciconiiformes has included a variety of large, long-legged wading birds with large bills: storks, herons, egrets, ibises, spoonbills, and several others. However recent DNA evidence might suggest that every member, except storks, are more related the Pelecaniformes, and thus belong to that group.1 Ciconiiformes are known from the Late Eocene.
They occur in most of the warmer regions of the world and tend to live in drier habitats than the very similar herons, spoonbills, and ibises; they also lack the powder down that those groups use to clean off fish slime. Storks have no syrinx and are mute, giving no bird call; bill-clattering is an important mode of stork communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, and small birds or mammals. There are 19 living species of storks in six genera.
Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Anschütz's famous 1884 album of photographs of storks inspired the design of Otto Lilienthal's experimental hang gliders of the late 19th century. Storks are heavy, with wide wingspans: the Marabou Stork, with a wingspan of 3.2 m (10.5 ft), joins the Andean Condor in having the widest wingspan of all living land birds.
Their nests are often very large and may be used for many years. Some have been known to grow to over 2 m (6 ft) in diameter and about 3 m (10 ft) in depth. Storks were once thought to be monogamous, but this is only partially true. They may change mates after migrations, and may migrate without a mate. They tend to be attached to nests as much as partners.
Storks' size, serial monogamy, and faithfulness to an established nesting site contribute to their prominence in mythology and culture.

Following the development of research techniques in molecular biology in the late 20th century, in particular methods for studying DNA-DNA hybridisation, a great deal of new information has surfaced, much of it suggesting that many birds, although looking very different from one another, are in fact more closely related than was previously thought. Accordingly, the radical and influential Sibley-Ahlquist taxonomy greatly enlarged the Ciconiiformes, adding many more families, including most of those usually regarded as belonging to the Sphenisciformes (penguins), Gaviiformes (divers), Podicipediformes (grebes), Procellariiformes (tubenosed seabirds), Charadriiformes, (waders, gulls, terns and auks), Pelecaniformes (pelicans, cormorants, gannets and allies), and the Falconiformes (diurnal birds of prey). The flamingo family, Phoenicopteridae, is related, and is sometimes classed as part of the Ciconiiformes.
However, morphological evidence suggests that the traditional Ciconiiformes should be split between two lineages, rather than expanded, although some non-traditional Ciconiiformes may be included in these two lineages.
The exact taxonomic placement of New World Vultures remains unclear.2 Though both are similar in appearance and have similar ecological roles, the New World and Old World Vultures evolved from different ancestors in different parts of the world and are not closely related. Just how different the two families are is currently under debate, with some earlier authorities suggesting that the New World vultures belong in Ciconiiformes.3 More recent authorities maintain their overall position in the order Falconiformes along with the Old World Vultures4 or place them in their own order, Cathartiformes.5 The South American Classification Committee has removed the New World Vultures from Ciconiiformes and instead placed them in Incertae sedis, but notes that a move to Falconiformes or Cathartiformes is possible.2
Some official bodies have adopted the proposed Sibley-Ahlquist taxonomy almost entirely, however a more common approach worldwide has been to retain the traditional groupings, and modify rather than replace them in the light of new evidence as it comes to hand. The family listing here follows this more conservative practice. Bird taxonomy has been in a state of flux for some years, and it is reasonable to expect that the large differences between different classification schemes will continue to gradually resolve themselves as more evidence becomes available.
However, recently a DNA study found that the families Ardeidae, Balaenicipitidae, Scopidae and the Threskiornithidae belong to the Pelecaniformes. This would make Ciconiidae the only group.

Distinct and possibly widespread by the Oligocene, like most families of aquatic birds storks seem to have arisen in the Paleogene, maybe 40-50 million years ago (mya). For the fossil record of living genera, documented since the Middle Miocene (about 15 mya) at least in some cases, see the genus articles.
Though some storks are highly threatened, no species or subspecies are known to have gone extinct in historic times. A Ciconia bone found in a rock shelter on Réunion was probably of a bird taken there as food by early settlers; no known account mentions the presence of storks on the Mascarenes.
Order Ciconiiformes
The fossil genera Eociconia (middle Eocene of China) and Ciconiopsis (Deseado Early Oligocene of Patagonia, Argentina) are often tentatively placed with this family. A "ciconiiform" fossil fragment from the Touro Passo Formation found at Arroio Touro Passo (Rio Grande do Sul, Brazil) might be of the living Wood Stork M. americana; it is at most of Late Pleistocene age, a few 10.000s of years; it is at most of Late Pleistocene age, a few 10.000s of years10.
The modern English word can be traced back to Proto-Germanic *sturkaz. Nearly every Germanic language has a descendant of this proto-language word to indicate the (White) stork. Related names also occur in many Eastern European, especially Slavonic languages, originating as Germanic loanwords.
According to the New Shorter Oxford English Dictionary, the Germanic root is probably related to the modern English "stark", in reference to the stiff or rigid posture of a European species, the White Stork. A non-Germanic word linked to it may be Greek torgos ("vulture").
In some West Germanic languages cognate words of a different etymology exist. They originate from *uda-faro, uda being related to water meaning something like swamp or moist area and faro being related to fare, so *uda-faro being he who walks in the swamp. In later times this name got reanalyzed as *ōdaboro, ōda "fortune, wealth" + boro "bearer" meaning he who brings wealth adding to the myth of storks as maintainers of welfare and bringing the children:
In Estonian, "stork" is toonekurg, which is derived from toonela (underworld in Estonian folklore) + kurg (crane). It may seem not to make sense to associate the now-common white stork with death, but at the times they were named, the now-rare black stork was probably the more common species. 11.
In Western culture the White Stork is a symbol of childbirth. In Victorian times the details of human reproduction were difficult to approach, especially in reply to a younger child's query of "Where did I come from?"; "The stork brought you to us" was the tactic used to avoid discussion of sex.citation needed This habit was derived from the once popular superstition that storks were the harbingers of happiness and prosperity, and possibly from the habit of some storks of nesting atop chimneys, down which the new baby could be imagined as entering the house.
The image of a stork bearing an infant wrapped in a sling held in its beak is common in popular culture. The small pink or reddish patches often found on a newborn child's eyelids, between the eyes, on the upper lip, and on the nape of the neck are sometimes still called "stork bites". In fact they are clusters of developing veins that often soon fade.
The stork's folkloric role as a bringer of babies and harbinger of luck and prosperity may originate from the Netherlands and Northern Germany, where it is common in children's nursery stories.
The Bible references the stork e.g. in Leviticus 11:19.
In Walt Disney's 4th classic Dumbo, the stork (more generally "Mr. Stork") delivers babies to their animal mothers. At the beginning of the film, he delivers Dumbo to Mrs. Jumbo. He is voiced by Sterling Holloway.
Several Warner Bros. cartoons — including Stork Naked and Apes of Wrath — cast a stork as a perpetually drunken employee of a baby-delivery service. Always losing his cargo en route to the intended recipients, the stork would find a replacement (always the wrong species) and deliver it to his clients. The stork was a bit player in these shorts, appearing at only the beginning and the end (where he returns to correct his mistake); the rest of the cartoons played out the interaction between the parents and the mismatched "child" they attempted to raise.12
Vlasic uses this child-bearing stork as a mascot in North America for its brand of pickles, merging the stork-baby mythology with the notion that pregnant women have an above-average appetite for pickles.
The white stork is the symbol of The Hague in the Netherlands, where about 25 percent of European storks breed, as well as of Poland, where the majority of the remainder breed(35%). It is also a symbol of the region of Alsace in eastern France. It is also the national bird of Belarus. In Vietnam, the stork symbolize the strenuousness of poor Vietnamese farmers and the diligence of Vietnamese women.
If not otherwise indicated, these usually refer to the White Stork (Ciconia ciconia).
