The document discusses the reproduction and birth of storks. It describes their courtship rituals including posture displays and wing movements. Storks lay mostly white eggs between March and April, usually 4 eggs per nest. Both parents take turns incubating the eggs for 32-34 days. When hatched, the chicks have downy white feathers and black beaks. The parents carefully feed and care for the chicks until they can fly at around 55 days old, then the young storks leave the family after 3-5 years to form their own families.
