The lion has at least nine distinct vocalizations, including a series of grunts that serve to maintain contact as a pride moves about. The roar can be heard up to 9 km away and is usually given shortly after sundown for about an hour, and then again following a kill and after eating. This has a territorial function.
Lions are losing their habitat due to the expansion of human activity (primarily agriculture) and human settlement. Lions are also hunted for sport and persecuted as a predator where they come into conflict with domestic cattle herds.
