Microscopic analysis of eggshell structure by Konstantin Mikhailov in 1995 found that the eggshells of shoebills closely resembled those of other Pelecaniformes in having a covering of thick microglobular material over the crystalline shells. Based on osteological evidence, the suggestion of a pelecaniform affinity was made in 1957 by Patricia Cottam. Traditionally considered as allied with the storks ( Ciconiiformes), it was retained there in the Sibley-Ahlquist taxonomy which lumped a massive number of unrelated taxa into their "Ciconiiformes". Alternative common names are whalebill, shoe-billed stork and whale-headed stork. The genus name comes from the Latin words balaena "whale", and caput "head", abbreviated to -ceps in compound words. He placed the species in its own genus Balaeniceps and coined the binomial name Balaeniceps rex. Gould provided a more detailed description in the following year. John Gould very briefly described it in 1850 from the skin of a specimen collected on the upper White Nile by the English traveller Mansfield Parkyns. The shoebill may have been known to Ancient Egyptians but was not classified until the 19th century, after skins and eventually live specimens were brought to Europe. Molecular studies have found the hamerkop to be the closest relative of the shoebill. ![]()
