upupoideæ

from The Century Dictionary.

• A superfamily of tenuirostral picarian birds, approaching the passerines in many respects, but most nearly related to the hornbills, containing both the terrestrial and the arboricole hoopoes (not the plume-birds: see Epimachinæ). The group is peculiar to the Old World, and is chiefly African. There are 2 families, Upupidæ and Irrisoridæ.
