This video is not mine! Recently, I often see it on the Internet. It illustrates very well how baby-storks come to us. Parents throw them out of the nest if the babies are sick, weak or unnecessary (in dry summers when there is little feed). Returning the baby to the nest is useless - the parents will throw it out again. By returning it, you will only increase the risk of injury. The chick will not die to the ground because it is too light. But it can break a wing or leg.
