@sheriwolfe: Turn up volume! 😃 Male lion in Linyanti, Botswana expressing a contact call with his brothers to let them know where he is. They do this to ensure their territory remains protected. They cruise around the outer limits of their territory, marking it along the way so other predators know the territory is taken. Three male lion siblings live in this territory. #lion #lions #Botswana #nationalgeographic #wildlife
