The main places of the black stork inhabitation are the combination of old forests or even groups of old trees with various marshes, riverbanks and lakes.
After the arrival at the end of March - beginning of April bird couples begin to built nests on the branchy trees, among the lateral branches. One nest, made of knots, serves to black storks several years.
Black stork usually brings 4-5 eggs in one layer. Both parents are taking part in the nest sitting, which begins with the first egg. So appearing of nestlings is not simultaneous. Nestlings feed on belch for 4-5 times per day.
Adult black storks are feeding on fish, frogs and water reptiles.
