Photos: Life in migration

Wildlife species make their quests to mate, give birth, feed and seek shelter across the American West.

The unexpected sight of a bighorn sheep from a curvy mountain road or a herd of elk emerging from the forest’s shadows at dusk can give a person an illuminating glimpse into the lives of our wild fellow creatures. In Wild Migrations: Atlas of Wyoming’s Ungulates, the reader learns how these snippets of animal encounters intersect with the bigger picture: the arduous and complex migratory journeys that many wildlife species make on their quests to mate, give birth, feed and seek shelter across the American West.

Writer Emilene Ostlind, a former HCN intern and editorial fellow, vividly describes animal migration, explaining how researchers track wildlife movements and the important role conservation efforts play in preserving habitat. These stories, accompanied by intriguing scientific observations, illustrations, sweeping maps and photography, take readers on their own journey into the mountains and grasslands of Wyoming, the rugged landscape many of these animals call home.
