 In Wyoming, we often use migratory birds as a signal that spring is near. Birds travel hundreds if not thousands of miles to make it to Wyoming each spring. Birds make migrations to avoid harsh winters and utilize bountiful summer seasons. The timing of when birds make migrations from location to location is known as phenology. Birds phenology is affected by seasonal and climatic variations. Migration trips vary in length and can take up to several weeks to accomplish. Transition habitats are important areas for migratory birds as resting spots for making their annual migrations. Some common and highly visible migratory species we see in Wyoming include mountain bluebirds, hummingbirds, waterfowl, and goldfinches. These birds can be found near habitats with plentiful food, water, and cover. Wyoming is lucky to have so many beautiful bird species. Looking for migratory birds each spring is a great way to break cabin fever. From the University of Wyoming Extension, I'm Brian Sebade, Exploring the Nature of Wyoming.
