How do people communicate with honeyguide birds?
Short answerTrueEmerging research
With a specific learned call, and it differs by community: Yao hunters in Mozambique use a trill followed by a grunt, Hadza hunters in Tanzania use a whistle, and other peoples use other signals. Birds respond most strongly to the signal used locally, which implies they learn a regional convention rather than responding to human sound in general.
The experiment that showed it
A cross-regional playback study compared local human signals against signals from elsewhere. Birds responded more readily to the call used by their own local human community, and less to the equivalent call from another region — the pattern you would expect if the association were learned rather than innate.
That puts a learned tradition on both sides. The hunters learn the call from their fathers and use it for nothing else. The birds appear to learn which human sound is worth approaching in the area they live in.
What the calls are for
Honey hunters do not simply follow a bird that happens to turn up. They call it as they walk, which advertises that a competent nest-opening animal is available and looking. The signal is doing recruitment work, and the measured effect is on whether a bird arrives at all rather than on how it behaves once it has.
