![]() Males and females are pretty much similar in color and appearance, with the main difference being that males are slightly larger and have longer bills. Shoebills in captivity have been reported to live more than 30 years and it is believed that they can potentially exceed 50 years of age under optimal conditions.Īdult shoebills are predominantly grey in color, with a few white tufts in the back of their head (see image below). Their legs are long and skinny. Legs are long and skinny, a typical trait among wading birds. It has an average length of 30 cm (12 inches) featuring a major hook at the tip. Their beak is, as mentioned before, is shoe-shaped, tan in color and many times accompanied by dark blotches. Shoebills weigh from 4 up to 7 kg (8.8-15.5 pounds). Their wings are very powerful and have a span of 230–260 cm (91–125 inches). They may be fed by the adults for up to a month after this time.Shoebills are very large stork-like birds with the adults being 115–150 cm (45–60 inches) tall, with a length ranging anywhere from 100 to 140 cm (40–55 inches). The young are fully fledged and can leave the nest by walking on about the 95th day of their lives – however it is about another 10 days before they can fly. They feed on regurgitated food from the adults bill, until they are about 30 days old when they can start accepting whole fish. The young of the Shoebilled Stork are always attended by one adult or the other who protects them and shades them from the sun. ![]() The eggs and the small chicks may be doused with water on hot days. Normally the female does all the night shift and half the day shift, meaning she does 3 quarters of the incubation. Normally two eggs are laid and both partners are involved in the incubation of the eggs, which lasts about 30 days. This mound may be 3 metres across and the nest itself is 1 to 1.7 metres across.īoth sexes participate in building the nest. The nest is built on a large mound of floating vegetation. In most places Shoebills appear to defend territories, their nests are usually found in the centre of the territory. Shoebill Storks are monogamous and nest solitarily, normally with the nests well spaced out, less than 3 pairs per km 2. Shoebill Stork successfully hunts for fish The Little Bittern is strongly nocturnal in contrast to its American cousin the Least Bittern which is distinctly diurnal.Ĭhecklist of Bitterns of the World Common Name It will nest anywhere from just above water level to 3m (10 ft) up in a water’s edge tree. Little Bitterns, the only other Bittern in Europe, is not limited to reed beds in its distribution, though it likes thick vegetation to skulk in. The nest is built, the eggs incubated and the young raised entirely by the female. The European Bittern builds its nest about water level on matted roots in reed beds. It is migratory visiting as far north as Canada during the summer. lentigrosus, is not quite as restricted to reed beds as is the Eurasian species and can be observed in less concealing wetland habitats. Unlike other herons, they nest solitarily – with one or more females choosing to mate with a territory-holding male for the right to live in his territory. Males defend territories with their loud booming calls, which can be heard by humans up to 5 miles away. It is believed to be polygynous, with males having more than one mate. The Eurasian Bittern is a partial migrant in Britain where it has suffered considerable decline in numbers in the last 200 years – due to extensive habitat destruction. Ixobrychus contains 8 smaller species known as Little Bitterns about which much less is known. poiciloptilus, the Australian Bittern, B. The subfamily Botaurinae contains 2 genera, Botaurus and Ixobrychus.īotaurus contains the four larger species B. Bitterns like Herons have powder down patches which they can use to help clean their plumage. Their colouration, combined with their habit of sitting upright with their heads back and their bills pointed skyward, can make them very difficult to spot.Ī number of the smaller species can climb up reeds and fly readily, but the larger species prefer to walk. They have shorter necks and legs than the rest of the Herons and are cryptically coloured.
