The shoebill (Balaeniceps rex), also known as the whale-headed stork, whalebill, and shoe-billed stork, is a large long-legged wading bird. It is named for its enormous, shoe-shaped bill. It has a somewhat stork-like overall form and was previously classified as a stork in the order Ciconiiformes, but genetic evidence has now placed it along with pelicans, herons, and its closest relative, the hamerkop, all in the order Pelecaniformes. Adults are mainly grey, while juveniles are browner. It lives in tropical East Africa in large swamps from South Sudan down to Zambia.
The shoebill may have been known to Ancient Egyptians, but was not classified by Europeans until the 19th century, after skins and eventually live specimens were brought to Europe. John Gould very briefly described it in 1850 from the skin of a specimen collected on the upper White Nile by English traveler Mansfield Parkyns. Gould provided a more detailed description in the following year. He placed the species in its own genus Balaeniceps and coined the binomial name Balaeniceps rex, from Latin balaena 'whale' and caput/ceps 'head'. Other common names are whalebill, shoe-billed stork, and whale-headed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Shoebill sighting in Lake Mburo National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 302nd most-seen of the 362 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Shoebill in Lake Mburo National Park on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 parks where we can rate Shoebill sightings, Lake Mburo National Park ranks 4th at under 5%. The best odds are in Murchison Falls National Park (Uganda, about 10%), Virunga National Park (Democratic Republic of the Congo, under 5%) and Queen Elizabeth National Park (Uganda, under 5%).
Same order: Pelecaniformes
The closest relatives of the Shoebill that you can see in Lake Mburo National Park (order Pelecaniformes, Pelicans, Herons, Ibises, and Allies) are Hadada (about 50%), Hamerkop (about 50%) and Cattle Egret (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Shoebill is recorded against all the birds logged in Lake Mburo National Park (14 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
