Posted @withrepost • @natgeo Photo by Beverly Joubert @beverlyjoubert | The great wildebeest migration of the Maasai Mara and Serengeti is an incredible sight: a natural phenomenon that brings in many thousands of tourists. Millions of animals have been following these ancient routes yearly, and fossil evidence suggests they’ve been in the area for a million years. Somehow they know when they need to move, and they go suddenly—on mass, following rains and fresh grass. They’re usually quite predictable, but this year they started a full month earlier than usual. If this is due to changes in weather patterns as is being suggested by ecologists, it’s going to be interesting to see how well the animals do this calving season and if this sudden shift is yet another warning to us that the natural world is under immense strain. #wildebeestmigration #maasaimara #ancientmigrations #changingecosystems #thereisnoplanetb https://www.instagram.com/p/BzTG4hiCohq/?igshid=b8uyzxyhphfi
