A prehistoric relative, Ephippiorhynchus pakistanensis, has been described from Late Miocene
fossils found in Pakistan
. At about the same time, another now-extinct species occurred in eastern to central Africa.
These large wading birds breed in marshes and other wetlands, building a large, deep stick nest in a tree. Like most storks, they fly with the neck outstretched, not retracted like a heron
; in flight, they present a strange shape, with the head and large bill somewhat drooping down. They are silent except for bill-clattering at the nest.

These birds are not infrequently kept in captivity by zoos or aviculturalists

The genus name Ephippiorhynchus is derived from Ancient Greek
ephippos, a saddle (literally "something which is placed on a horse"), and rhynchus, "bill", and refers to the frontal shield which saddles the bill of one species.
