We where in Tanzania and our guide took us out into the scrubland and then after a 30 minute walk we came to a cave entrance with these three members of the Hadza tribe - a hunter gatherer group. The Hadza have no permanent home and find caves or pitch rudimentary tents wherever they need to. From there they fan out to hunt and search for food. We found them to be very welcoming and friendly and later they allowed us to follow them on a hunt for birds which they shot with a bow and arrow.
