Extraordinary Migration of Mongolian Gazelles
In Extraordinary Migration of Mongolian Gazelles, narrator Sir David Attenborough explains how gazelles all come together once a year, and nearly all gazelle calves are born within the space of 10 days. This provides protection against predators in an environment where there are few places to hide. This video is excerpted from BBC's Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
