That's not the only reason, though. I do like programs about nature and there are some excellent documentaries on Foxtel - which is where I saw a doco on the great wildebeest migration.
Wildebeests or gnus are antelopes that come into the category of having faces only a mother could love - they have been described as looking like they are made up of leftover bits of other animals - but they are beautifully designed for their herbivorous life style. There are two species - the blue (the majority of wildebeests) and the black. They are large and very strong - an adult can even injure an attacking lion, these being one of their main predators along with cheetahs and hunting dogs.
Most - but not all - wildebeest travel in huge herds following new grass. In the case of the wildebeest of the Masai Mara and Serengeti, this leads them to make one of the great migrations of the animal world as they travel between 800 and 1,600 kilometres from the south eastern Serengeti west towards Lake Victoria then north to the Mara region and return. They often move in long spread out strings as well as groups. Driven by the need to move for food they let nothing stop them moving forward. This includes swimming crocodile infested rivers and lakes often in such a crush of bodies that animals (particularly calves) are drowned while the crocodiles seize any stragglers. It's both breathtaking and horrifying to watch.
