When wildlife researcher Jonathan Slaght was a young Peace Corps volunteer in the Russian Far East, he caught a brief glimpse of a Blakiston's fish owl. It was the furthest south the species had been documented in over a hundred years, and a chance encounter that would change his life. In Owls of the Eastern Ice, Slaght tells the story of his decades-long quest to safeguard the world's largest owl from extinction in Primorye, a remote Russian province dominated by Ussuri taiga forest, the only place in the world where brown bears, tigers and leopards co-exist. The fish owl lives exclusively along the rivers of Eastern Russia, Northeastern China, and Japan's Hokkaido Island, and can best be tracked in the winter snows, so very little is known about it. Now Russia's evolving fortunes, logging interests and climate change present new threats to the owl's survival. In this breath-taking nature and adventure story, Slaght recounts his experiences pursuing the owl through its forbidding territory, during months-long journeys covering thousands of miles, so that he and his fellow researchers can learn how to protect this endangered giant. Along the way he spends time with the Russians who inhabit the taiga and must survive in the harshest and most isolating of conditions. As much a portrait of the world's most extraordinary owl as of the Russian Far East itself, Owls of the Eastern Ice is a timely meditation on our relationship with the natural world and what it means to devote one's life to a single pursuit.
