One of the greatest shows on Earth is now available in real time. The great wildebeest migration across the Serengeti plains went live on Tuesday, via the Periscope app and YouTube live streaming.The migration, dubbed the seventh natural wonder of the world, is being broadcast by HerdTracker, a web app platform, in partnership with Makeit Kenya.com.Until Monday, viewers around the world will be able to use their mobile phones, tablets and PCs or laptop computers to watch - in real time, for the first time - hundreds and thousands of wildebeest, zebra and antelope thunder across the plains and across treacherous waters on their way to greener pastures. On day one there were more than 10000 views on Periscope.HerdTracker, the free web app created by safari operators Discover Africa, plots the location of the herds in real time to a Google map and sends instant updates, photos and information to users' devices.The platform helps tourists plan safaris and increases their chances of witnessing the migration.Contributors to the live update include pilots flying over the parks, safari guides, rangers, lodges and hot-air balloonists.With the launch of Periscope by Twitter in March, Carel Verhoef and Andre van Kets, the co-creators of HerdTracker, decided to use this new technology to bring small snippets of the migration to the world, live from Kenya's Masai Mara. The broadcast will take place twice daily, with in-depth commentary. In South Africa, coverage is from 7.30am to 8am and 8.30pm to 9pm each day.The migration is an annual continuous movement of the herds - in excess of twomillion animals - through the Serengeti/ Mara ecosystem.The herds move back and forth across the Mara River throughout the three to four months from about late June to the end of October each year.Register your e-mail address on discoverafrica.com/herdtrackerlive for reminders of broadcasts...
