Birding without Borders by Noah Strycker

Subtitle: An Obsession, a Quest, and the Biggest Year in the World -- What an adventure!  He does go all around the world and the birds he sees, the adventure he has, and the people he meets is just amazing.  I really liked how he met local people, used them as guides, and just got to know them, their families, and the culture.  You would need to be someone willing to step out of your comfort zone to do this kind of thing and he embraced it.  Even if you are not a birder you will enjoy this book, a great read.
