White stork

The white stork has long been the bird in legends and storybooks that delivers babies to people. This large, long-legged bird commonly lives in open marshes and fields. It may build its huge nest on the top of a building. It is the most common stork species.

White storks stand 39 1/2 to 49 inches (100 to 125 centimeters) tall and weigh between 5 and 10 pounds (two to five kilograms). They have white plumage on their bodies, tails, necks, and heads. Their long, straight, sharp bills and long, slender legs are bright orange. The front edges of their wings are also white, and the rear edges are black.

Colonies of white storks inhabit marshlands and open fields across portions of Europe, Asia, and Africa. They build their huge nests on rocks and in trees. Their nests, along with those of eagles, are the largest nests of all the world's birds. Each nest of sticks may be over five feet (1 1/2 meters) across and almost as deep. Some storks are comfortable enough around people that they build their nests on top of buildings and houses. Such nesting sites have been popular for centuries among storks. Nests in these places may also contain paper, rags, and even clothes snatched from clotheslines.

The marshlands and fields where storks live provide a great supply of earthworms, crickets, and grasshoppers for the storks to eat. The birds may hunt baby rabbits, rodents, and even the chicks of other birds that nest on the ground.

All white storks migrate between winter ranges and breeding grounds, whether they migrate only short distances or fly much greater distances. They are strong fliers with wingspans that are 61 to 84 1/2 inches (155 to 215 centimeters).

As winter in the north ends and spring arrives, the male stork returns to the breeding grounds in March or April. He begins repairing and enlarging the nest he and his mate used the previous year. She returns to the nest a few days later. Courtship includes soft cooing noises between the male and female, and noisily warning intruders to stay away. After mating, the female lays two to five eggs. The male and female incubate the eggs for 33 to 34 days. They feed regurgitated food to the young. The chicks may fly from the nest after 58 to 64 days. They mate when they are three or four years old.

White storks have a lifspan of 20 to 35 years.
