Today I found out why storks are associated with delivering babies.

We all know how babies are made. The stork can be seen flying over rooftops with a little cloth bundle before landing at the doorstep of a happy couple who then unwrap their precious, smiling newborn—right? This myth was once a common story to tell children who were deemed too young to be told anything different.

Storks have been associated with babies and family for centuries. In Greek mythology, they were associated with stealing babies after Hera turned her rival into a stork, and the stork-woman attempted to steal her son. In Egyptian mythology, the soul of a person—the ba—was usually represented by a stork. The return of a stork meant the return of the soul, at which point the person could become animated again. In Norse mythology, the stork represented family values and commitment to one another.

In several mythologies, storks are also a symbol of fidelity and monogamous marriage because storks are widely believed to mate for life. In truth, they don’t actually mate for life, but do have a tendency to return to the same nests every year and usually mate with the same partner.

Storks are also represented in Chinese, Israeli, and various European cultures mythologies, but the association of storks bringing couples a newborn baby is believed to have started in Germany several hundred years ago.

The natural behaviour of storks lends a clue to their association with birth. As a migratory bird, white storks would fly south in the fall and return to Europe nine months later. Usually they could be seen heading north and nesting around March and April. Babies born in March and April were likely conceived in June of the previous year. Midsummer’s Eve, which takes place on June 21, is a celebration of the summer solstice, but it is also a pagan holiday of marriage and fertility. As many marriages and other couplings would take place during this time, many babies would be born around the time that the storks could be seen flying north, making the connection that the “stork brought the baby.” The symbolism of their migration pattern combined with their history in myths and legends probably contributed to the popularity of the story today.

Hans Christian Andersen popularized the fable in The Storks, a short story he wrote in the 19^th century. In the story, storks flying above a village are teased by a young boy and get their revenge by delivering a dead baby to the child’s family. In this version of the story, the storks plucked babies from a pond where they were dreaming, to deliver them to families of good children. Another popular version of the story was that babies were found in caves called Adeborsteines—which, in German, literally means “stork stone.” Adeborsteine can also refer to stones from which babies would “hatch”; black and white stones that children threw over their heads to tell the storks that they wanted a sibling; or stones that babies were laid upon to dry after they were pulled from the sea.

The story was likely spread due to the perceived, and slightly odd, human necessity to waylay children’s awkward questions for as long as possible. In Hans Christian Andersen’s time, baby-making was particularly a taboo topic. Even today, many children get siblings before they are deemed ready for “The Talk” but their curious nature means parents have to tell them something. Because of their long history associated with babies and family, storks are an easy story to tell kids sometimes in the same breath as teaching them valuable life lessons like always being honest…

Bonus Facts:

• In some countries, it was believed that placing sweets in the window was a way to let the storks know that the family in the home was ready for a baby.
• In ancient Greece, there was a law that demanded children take care of their parents in old age. The law was called “Pelargonia,” which is derived from the Greek word for storks—“pelargos.” Storks tend to care for their young long past when the young are able to fly and fend for themselves, which led to the belief that the young were looking after the old instead. It is yet another way in which storks and children are connected.
• Seen as a symbol of good luck, storks had a tendency to nest on people’s roofs and chimneys and it was believed that storks on the roof would result in children for the couple living in the home.
• March, the month in which many midsummer babies were born, was once considered a lucky time of the year to give birth.
• Storks have a high tolerance for the presence of human beings and are not easily frightened by us.
• There are several versions of the stork story that aren’t as happy as the one we know today. For instance, in Poland the stork’s white feathers had been given to it by God, while the Devil gave it the black tips, making it both good and evil. In England, the bird was believed to be a symbol of adultery. In Germany, a handicapped baby had been “dropped” by the stork to punish a couple for past sins.
• Black storks also exist, and are all black except white underbellies, but white storks are the ones associated with babies—likely because of white symbolizing purity.
• Storks raise one brood a year—typically around four hatchlings, though as many as seven has been recorded. In a strange twist on the story, storks are known—like other animals—to kill their own young in times of famine. Perhaps they aren’t the creatures we should be entrusting with our newborns after all!
• The white stork’s scientific name is Ciconia ciconia. Ciconia is the Latin word for stork, first used by Ovid and Horace.
