The relationship between humans and animals seem to have deep levels as in Mozambique some wild birds play a crucial role of honeyguides for the local population.
Human honey-hunters use a simple sound “Brrr-hm”, and the birds immediately start roaming from tree to tree guiding the hunters to bees with 100 percent accuracy. Scientists are fascinated by this method and want to investigate this relationship between honey-hunters and wild birds.
The “brrr-hm” sound was compared to other sounds to establish its efficiency. As it turned out, the traditional sound was three times more efficient than control sounds. When you make the wrong noise, the accuracy is only 16 percent, whereas when you make the right sound, the accuracy increases to 54 percent.
It means that 1 out of 2 attempts of finding honey is successful. According to biologists, this method is more like a trade between information and skills. One of them volunteered to try and imitate the sound but as expected the volunteer failed until the experienced honey-hunter made the right noise leading them to honey.
The pattern of the sound is based on the fact that it must come out from the back of the throat. Experts were not able to determine yet how these wild birds are so efficient in finding honey, but it is speculated that honeyguides have an excellent sense of smell.
However, these bee nests are hidden in trees, and it is a very challenging process for birds to reach them. Also, bees usually sting the birds and sometimes even kill them. The local communities who rely on honey use special tools and methods, including axes and smoke to reach the nests and get rid of the bees, thus reducing the risk of getting stung.
These nests are still very hard to find even for the Yao people, and this is what makes this method so important and difficult to master. In time, the Yao developed this sound that makes the honeyguides lead the honey-hunters to bees.
After humans have reached the nest, they chase away the bees with smoke and collect the honey, whereas wild birds eat the wax. This connection between humans and birds is even more fascinating because these are wild birds.
They are not trained or domesticated by humans as in the case of dogs and other pets. Some experts even stated that honey-hunters connection with honeyguides is most likely the deepest bird-human relationship on the planet.
