I've seen most of these animals in these situations. The first four episodes center on each season of the calendar. The fifth episode seems to be a bit of a random spin around the globe. The last episode deals with the scientists doing their research work around the world.
This is an ITV show co-produced by Fox Nation. Stephen Fry is the narrator. He could be the new David Attenborough if he wishes and he gets his hands a little bit dirty. He should get out of the recording studio and get his face on the show especially on that last episode. This jumps from one animal to the next without much connective tissue. The last episode is a little different in that they focus on people who are doing the real work. I do like that more for the actual science. As with some Fox shows, I do watch out for any climate change bias. The last episode deals with that a lot more and do it properly. The first five episodes have the pretty pictures, but that last one is more important.
