I just thought people on the blog might be interested in the new BBC nature series "Earthflight" starting tonight 8.00pm BBC One. The promotional blurb says "...provides a bird's-eye view of the world, joining our feathered friends as they soar across 6 continents..." - so it sounds as though its mostly about birds. See:

Enjoy!
