Honeyguides (family Indicatoridae) are in the order Piciformes, similar to the transient birds.

They are also known as indicator birds or honey birds, although the latter term is also used more specifically to refer to the Prodotiscus species.

They have a tropical distribution in the Old World, with the most species in Africa and two in Asia.

These birds are best known for their encounters with humans.

Honeyguides are noted and named for one or two species that will purposely lead humans (but, contrary to common reports, not honey badgers) directly to bee colonies so that they can feast on the grubs and beeswax left behind.

Description

Most honeyguides are dull-colored, but some have a bright yellow color in the plumage. They all have light outer tail feathers that are white in all African species.

Among the few birds that regularly feed on wax—beeswax in most species, and probably waxy secretions of scale insects in the Prodotiscus genus, are to a lesser extent in Melignomon and smaller Indicator species.

They also feed on waxworms, which are larvae of the Waxmoth Galleria mellonella, on bee colonies, and on flying and creeping insects, spiders, and occasional fruits. Mixed-species feeding flocks accompany many animals.

Behavior

Honeyguides are named for a remarkable habit in one or two species: leading humans to bee colonies. The bird feeds on the remaining larvae and wax if the hive is opened and the honey is taken.

This behavior is well studied in the larger honeyguide; some authorities (following Friedmann, 1955) note that it also occurs in the scaly-throated honeyguide, while others do not agree.

Wild honeyguides have shown the ability to understand a human call to assist them in finding honey.

Some scientists claim that honeyguide’s co-evolution with humans dates back to the stone tool that made the human ancestor Homo erectus about 1.9 million years ago.

Despite common belief, there is no proof that honeyguides guide the honey badger; while there are videos about this, there is no evidence.

The Greater Honey Guide (Indicator Indicator) is named for a remarkable skill: leading humans to bee colonies by recognizing the human call to help them. When humans open the hive and the honey is taken, the bird feeds on the remaining larvae and wax.

But just like anything else, the honeyguide, in one of the few mutualistic relationships between humans and a wild, free-range animal, has some redeeming attributes, including one that helps people in particular.

Honeyguides eat wax—one of many birds that can ingest it. The first written account of this unusual feeding activity dates back to 1588 when a Portuguese missionary in Mozambique found a honeyguide nibbling on his candlesticks.

But wax—along with other beehive contents such as bees, honey, bee larvae, and pupae, all of which honeyguides like to eat—is a little hard to come by nature, so bee colonies are pretty much your only choice when the wax is a staple in your diet.

But beehives are often notoriously difficult to access—they are often installed in hard-to-reach tree cavities, and the bees themselves sting and swarm. So the honeyguide needs a little help: a smart, fearless partner.

Since time immemorial, humans have been helping honeyguides crack bee colonies. Indigenous people, including the Yao community in Mozambique, have a smoke to soothe the bees and the axes to break open logs.

What the honeyguide has to do is take people to the nest. And this contact between a person and a honeyguide is simpler than you would imagine.

Many birds fear humans, but honeyguides actively pursue humans to attract them across the savannah to the bee colony they know will produce enough honey, comb, and bees for both partners.

People in the Yao group talk to honeyguides with a particular call to let them know when they’re ready to hunt and trust the birds to take them to the nest, often a mile (2 km or so through the forest).

Breeding

Honeyguide chicks have been known to expel the chicks of their hosts from their nests physically, and they have needle-shaped hooks on their beaks, which puncture the host’s eggs or destroy the chicks.

African honey-guide birds are known to lay their eggs in the underground nests of other wax-eating bird species.

Their reproductive technique is to lay an egg in the nest of another bird species (usually kingfishers, bee-eaters, barbets, and starlings), poking holes in all the nesting owners’ eggs while they lay their eggs.

Honeyguide chicks kill the host’s hatchlings with their needle-sharp beaks right after hatching, just as cuckoo hatchlings do.

The honey-guide mother ensures that her chick hatches first by brooding the egg internally for an extra day before laying so that it has a head start in development relative to the hosts’ offspring.

In this way, the honeyguides hoard all the food the adopted bird parents bring to the nest.

Reproduction

Males attract females by circling over a female while making drumming sounds with their wings.

After landing near the courted female honeyguide, the male approaches her, spreading his white-edged retrievers, fluttering his wings, and making a low, shrill call.

The mating mechanism is not well established as individuals do not engage in parental care and do not have an association after the mating.

Greater honeyguides breed between September and October. After mating, females lay their eggs in the nest cavities of other species. The female lays one egg per nest and lays between 4 and 8 per breeding season.

After laying the egg in the host nest, the female will pierce the host’s eggs to ensure the survival of her chicks.
