The small bird genus Geronticus belongs to the ibis subfamily Threskiornithinae. Its name is derived from the Greek gérontos in reference to the bald head of these dark-plumaged birds; in English, they are called bald ibises.

The ibis are a group of long-legged wading birds in the family Threskiornithidae that inhabit wetlands, forests and plains. "Ibis" derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the western cattle egret mistakenly identified in 1757 as being the sacred ibis.
