This was an exhaustive bit of reading. It was shock full of interesting facts. I liked it, though I have to confess that it left me swimming in a wide sea of information that I can't imagine remembering for very long afterward. I'd like to say that I recommend it to my students, but since all of them are ages 11 and under, I can't imagine them not being as overwhelmed as I was by the sheer volume of this text. This would be great to read if I were researching migratory animals. It's loaded with facts, but it can leave you feeling a bit bowled over by the end. ( )
