Kenya's Maasai Mara is renowned for lions. Massive, regal, fearless. They lounge during the day and hunt by night. Early one morning I came across three female lions hunting a hippo. The hunt was unsuccessful but the courage of a lion attacking an animal six times their size was amazing to watch.
Lions don't always have the savannah to themselves. Occasionally a pack of hyenas will surround a lion and literally steal the kill. I watched a poor lion look on sadly as a hyena ran off with dinner.
