This 14 November 2018 video says about itself:
When Birds Stopped Flying
Ratites have spread to Africa, Australia, New Zealand, and South America. And there are fossils of Ratites in Europe, Asia, and North America too. That’s a lot of ground to cover for birds that can’t fly. So how did Ratites end up all over the world?
Thanks to Ceri Thomas for the Lithornithid reconstruction.
