Bill-clattering is a behaviour of real storks. They can also let out a high pitched whine, and even make cow-like ‘moo’ noises.
Shoebill are solitary in their breeding habits, with typically less than 3 nests per square kilometer.
The nesting shoebill will vigorously defend their territory between 2 – 4 square kilometers (1 to 1.5 square miles) from other shoebill, and large birds.Shoebills chicks often bully, fight and can kill their siblings (known as ‘siblicide’) when only a few weeks old.
Rather disturbingly, this is actually rather common in larger birds. Often the older, and bigger chick, can hurt a smaller chick, while their parents are away from the nest eventually driving it to live away from the nest. Research suggests, this is due to energy efficiency and survival of the fittest.
The shoebill female always lays two eggs, but only one ever survives.
The second egg is seen like a ‘back up’, in case anything is wrong with the first egg. Usually the first to hatch survives only. 3
The Shoebill has long fascinated civilizations. They appear in wall paintings and hieroglyphics of ancient Egyptians, and it’s old Arabic name is Abu-markub, or ‘Father of a Slipper’.
