The female usually lays 3-5 eggs, more rarely up to seven. Parents share incubation duties for 33-34 days. Young chicks are covered with white down and have black bills. Both parents feed the young on the nest until they fledge at 8-9 weeks of age. Fledglings may continue to return to the nest site each evening to beg for food from their parents.
Young birds reach sexual maturity in their fourth year.
Banding records indicate that wild birds can live and reproduce successfully past 30 years of age. The overall population of White Storks has declined steadily over the last half century. The decline in Western Europe has been the most pronounced. Pollution, pesticides and wetlands drainage have severely reduced suitable foraging habitat across the breeding range. Storks no longer breed in southern Sweden, Switzerland, western France, Belgium or southern Greece.
