Lion hunters become defenders

In the Maasai heartland of southern Kenya, some young men have swapped their ancestral role as lion-hunters to instead protect the big cats under a conservation scheme that also aims to help their community.

Among them is Leiyio Lengete, a "Moran" - or warrior - who wears a scarlet blanket over his shoulders, a blue one around his hips, and a multitude of fine multicoloured beaded bracelets on his forearms, ankles and neck.

Large half-moon shaped metal earrings and a beaded headband set off his long elaborately braided hair, but instead of a traditional spear, he clasps a GPS receiver.
