Feeding habits of a Shoebill stork

Shoebills are solitary hunters who wait on their prey patiently. They stand in one place quietly only waiting for the prey to appear and attack.

It uses its keen eye sight to spot its prey in the vegetation and when it comes close, it gives a violate strike with maximum speed and it hardly misses on it, scooping it up with water and vegetation which later pour out.

It finds hard time holding large preys after striking them and it can take about 10 minutes struggling to hold it by its bill. It cuts large prey into pieces so that they are swallowed in intervals.

Breeding of the shoebill stork

Shoebills start nesting immediately at the end of a rain season. A couple clears an area of about 3m and then they build a very big nest on a floating vegetation.

A nest is usually 3 meters deep and about 2 meters wide. It is strong built from aquatic vegetation like papyrus, tree branches, and grass.

A shoebills lays about 1 to 3 big white eggs with each weighing about 164 grams, measuring 80 to 90 mm high and  54 to 61mm wide. They incubate for approximately 30 days.

They both involve in shading and protecting the eggs. When the female is away to feed, the man remains safe guarding. During very hot days, they fetch water using their mandibles to the nest to cool off the eggs. Although they usually hatch all of the three eggs, they hardly raise more than one chick.

Both the male and the female actively engage in brooding, feeding and guarding although the females are very much protective than the males. chicks are mostly fed on all lung fish and cat fish. Large preys are teared so they they have it in intervals.

By 112 days, the chicks can now fly and are allowed access to the vegetation to hunt. However, they will still be cared for , still fed and both parents always keep close to them. After like one month, they can then feed independently. Shoebills reach sex maturity at 3 years of age and practice polygamy just like humans.
