Impala, Aepyceros melampus, drinking at a water hole left by the dried up Moru River. (Featured in Live & Let Live.) It is interesting that the impala is almost camouflaged against the pebbles even though they are different colours. Females have tiny horns while males have long elegant horns. Impala live in groups of a male with his harem or groups of bachelor males. They like the shade in the heat of the day. Serengeti National park, Tanzania, East Africa.
