The Honey Guide bird in Africa has a special call just for speaking with humans!
The Maasai people of Africa whistle and communicate with the Honey Guide bird. The bird has a special call that it only uses when communicating with humans. They help the Maasai find honeycomb. The bird’s call changes as the Maasai get closer and closer to the honeycomb.
So, why does the Honey Guide help the Maasai? The Maasai return the favor and give the bird some of the honeycomb. If they didn’t give back, the bird could lead them into harm’s way the next time.
