When Arjan Dwarshuis first heard of the “Big Year”—the legendary record for birdwatching—he was twenty years old, it was midnight, and he was sitting on the roof of a truck in the Andean Mountains. In that moment he promised himself that, someday, somehow, he would become a world-record-holding birder. Ten years later, he embarked on an incredible, arduous, and perilous journey that took him around the globe; over uninhabited islands, through dense unforgiving rainforests, across snowy mountain peaks and unrelenting deserts—in just a single year.

Early in 2013 Neil Hayward was at a crossroads. He didn't want to open a bakery or whatever else executives do when they quit a lucrative but unfulfilling job. He didn't want to think about his failed relationship with 'the one' or his potential for ruining a new relationship with 'the next one'. And he almost certainly didn't want to think about turning 40. And so instead he went birding. Birding was a lifelong passion. It was only among the birds that Neil found a calm that had eluded him in the confusing world of humans.

In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.
