Query: Great Book

I recently got into birding and had just finished this book when I heard it had been made into a movie and would be out soon. Granted, it's "inspired by" the book, but it should be fun nevertheless.The book is hard to put down. But, if you're like me and read 3-5 pages and come back later, it's very easy to do that, too.Obmascick does a really good job of presenting competitive birding from different perspectives. There's a lot of inside information to get you wrapped up in. In some ways, it's like "Word Freak" was for Scrabble -- a view into a whole new world.This is probably a good gift book as well, for that reader on your list -- as you buy your own copy. ;)
