The Big Picture has some wonderful wildlife photography from National Geographic’s new epic documentary series “Great Migrations“.”Move as millions, survive as one”. That is the subtitle to the new seven-part television series from National Geographic called “Great Migrations”. Animals great and small are on the move around the world, chasing resources in dangerous journeys that might take mere hours or span generations. To capture the images and video for the series, National Geographic’s photographers spent two and a half years in the field, traveling 420,000 miles across 20 countries and all seven continents. There is some stunning wildlife photography previewed at the Big Picture – well worth a look. “Great Migrations” premieres this sunday night in Victoria Australia on Foxtel’s National Geographic Channel.
