A wild bird leads humans to beehives, then eats the leftover wax

In parts of Africa, the greater honeyguide bird calls out to human honey hunters and physically leads them to wild bee nests. The Hadza and Yao peoples in Tanzania and Mozambique reply with specific calls, and a 2016 study found birds were roughly three times more likely to lead people to honey when they heard the traditional call versus other sounds. Once the humans smoke out the hive and take the honey, the birds feast on the wax and larvae they can't reach alone.
