This is the great migration of Wildebeests in Serengeti, Tanzania. It starts with a simple get together and God knows how & where it will end. You will see dead, chaos, order, and confusion. I don't know why Zebras accompanied their friends! You might see Alligator at around the half, and it is there because the river is infested with them. At the end, a small group started the reveres migration and again animals got together started grazing.
