Breeding
The Black Stork builds a stick nest high in trees or on cliffs. It nests in Central Europe in April to May, and is a winter visitor to northern India, Nepal east to Myanmar.
Black Stork parents have been known to kill one of their young, generally the smallest, in times of food shortage to reduce brood size and hence increase the chance of survival of the remaining nestlings. Stork nestlings do not attack each other, and their parents' method of feeding them (disgorging large amounts of food at once) means that stronger siblings cannot outcompete weaker ones for food directly, hence parental infanticide is an efficient way of reducing brood size. Despite this, this behaviour has not commonly been observed.
