Honeyguides, (family Indicatoridae), are near passerine bird species of the order Piciformes. They are also known as indicator birds, or honey birds, although the latter term is also used more narrowly to refer to species of the genus "Prodotiscus". They have an Old World tropical distribution, with the greatest number of species in Africa and two in Asia.


Most honeyguides are dull-colored, though a few have bright yellow in the plumage. All have light outer tail feathers, which are white in all the African species.

They are among the few birds that feed regularly on wax—beeswax in most species, and presumably the waxy secretions of scale insects in the genus "Prodotiscus" and to a lesser extent in "Melignomon" and the smaller species of "Indicator". They also feed on the larvae and on waxworms (caterpillars of "Galleria mellonella") in bee colonies, and on flying and crawling insects, spiders, and occasional fruits. Many species join mixed-species feeding flocks.

Honeyguides are named for a remarkable habit seen in one or two species: they guide humans, and possibly other large mammals (such as the Ratel {honey badger}), to bee colonies. Once the mammal opens the hive and takes the honey, the bird feeds on the remaining wax and larvae. This behavior is well studied in the Greater Honeyguide; some authorities (following Friedmann, 1955) state that it also occurs in the Scaly-throated Honeyguide, while others disagree (Short and Horne, 2002).

Although most members of the family are not known to recruit "followers" in their quest for wax, they are also referred to as "honeyguides" by linguistic extrapolation.

The breeding behavior of eight species in "Indicator" and "Prodotiscus" is known. They are all brood parasites that lay one egg in a nest of another species, laying eggs in series of about five during five to seven days. Most favor hole-nesting species, often the related barbets and woodpeckers, but "Prodotiscus" parasitizes cup-nesters such as white-eyes and warblers. Honeyguide nestlings have been known to physically eject their host's chicks from the nest, and they have hooks on their beaks with which they puncture the hosts' eggs or kill the nestlings, by repeated lacerations if not in a fatal stab.cite book |editor=Forshaw, Joseph|author= Short, Lester L.|year=1991|title=Encyclopaedia of Animals: Birds|publisher= Merehurst Press|location=London|pages= 155|isbn= 1-85391-186-0]
