Probably 3.75 stars, bumped upward.
Per others, yeah, the title is misleading — well, until at least the last chapter, which I'll get to.
What this is actually about is the invention of modern GPS monitoring tags for animals to replace the old radiocollars that work fine in medium and large mammals, but obviously not on small ones, or birds — where, in the past, non-monitored leg banding was the only option.
Today, we have that and more — GPS tags (with photo in book) are small enough to even be on dragonflies. What inspired Wikelski to push to go there, and the actual trek to get there, is the subject of the book.
In addition to the science, especially since Wikelski didn't go too far down the road of picking sides, I liked the part about the struggles he and his German tech company had at times in dealing with Roscosmos.
Now, that last chapter? Wikelski gets heavily into futurism, with ideas about how there will be, indeed, an "Internet of Animals" predicting the weather, drought, earthquakes, avian flu, etc. (It should be noted that animals aren't necessarily perfect at predicting earthquakes, cannot predict tornadoes and other things.)
Besides being overblown in general, China not figuring a way to block health data on ducks at Poyang Lake comes to mind as a way in which this futurism scenario is probably overblown.
And, per one other reviewer, let's wait another year or two on how these Cube satellites do before saying this is working as well as Wikelski hopes.
Nonetheless, I'll still give this four stars, not three.
