One group of sandhill cranes skips the long migration to California and spends winter at Sauvie Island, near Portland. In summer, they head only to British Columbia, while other populations venture farther north to Alaska. This information was gleaned by researcher Gary Ivey after he put satellite trackers on the legs of cranes in Oregon and again in Alaska.
