Traveling to 41 countries in 2015 with a backpack and binoculars, Noah Strycker became the first person to see more than half the world’s 10,000 species of birds in one year.

In 2015, Noah Strycker set himself a lofty goal: to become the first person to see half the world’s birds in one year. For 365 days, with a backpack, binoculars, and a series of one-way tickets, he traveled across forty-one countries and all seven continents, eventually spotting 6,042 species—by far the biggest birding year on record.

This is no travelogue or glorified checklist. Noah ventures deep into a world of blood-sucking leeches, chronic sleep deprivation, airline snafus, breakdowns, mudslides, floods, war zones, ecologic devastation, conservation triumphs, common and iconic species, and scores of passionate bird lovers around the globe. By pursuing the freest creatures on the planet, Noah gains a unique perspective on the world they share with us—and offers a hopeful message that even as many birds face an uncertain future, more people than ever are working to protect them.
