The great migration: Wildebeest crossing the Mara river. The great migration must be one of the greatest wildlife spectacles on the planet. Huge numbers of Wildebeest (and some Zebra) were gathering on the Kenyan side of the Mara river. They were intent on crossing the river to reach better grazing in the northern Serengeti, Tanzania. It had been raining in the Serengeti and so the drive to cross this dangerous river was building day by day to reach the newly grown pasture. It was intriguing to watch as they almost dared each other to cross. But once one Wildebeest decided to take that first jump then many more follow immediately creating a scene of panic and pandemonium. The river holds many threats for the animals waiting to cross. Some will succumb to attacks by the many large crocodiles waiting in anticipation of the crossing. You can see my film of a Crocodile attack during a crossing at: https://wildlifeaction.co.uk/trips/crocodile-attack/. However, many more animals get washed away and drown whilst many others break limbs as the leap into the river and scramble to get out the other side. The corpses of the unlucky few provide sustenance for a wide range of other creatures.
