The feeding habits of herbivores

David Attenborough uses advanced surveillance technology to observe the feeding habits of herbivores, including elephants forced to undertake epic migrations to ensure a steady diet of the plants they need to survive. He also considers the habits of the sloth, which takes a month to digest each meal, and reveals scientific research suggesting that grazing wildebeest do not follow the rains as originally thought, but detect trails of phosphorus in the grass
