Maasai (or Masai) Giraffes, Giraffa camelopardalis tippelskirchi. Males Necking. Male giraffes often engage in necking, which can be to prove dominance or it can be sexual. They swing their necks in huge arcs using their heads as rattering rams. In young males such as these it is common for the winner of the battle to mount the other to show his sexual dominance. In real battles a giraffe can land a powerful blow with his head occasionally knocking a male opponent down.
