We watched a whole herd of Elephants cross the Mara river which was amazing to witness. The herd crossed the river in a group with the little ones in the middle and adults on the outside. We then noticed a male chasing a female through the water with his trunk over her back. He was clearly "looking for love". He chased her all the way accross the river and onto the other side. He eventually caught up with her and mated with her. Very romantic.
