Leptoptilos crumeniferus is known as a colonial breeder. It reaches sexual maturity when it is approximately four years old and usually mates for life. The stork lays its eggs in small nests made of sticks that hold two or three of its eggs. The Marabou breeds during the dry season because at this time the water levels are low, which make it easier to catch frogs and fish to feed the young. This stork may live up to 25 years.
