The current issue of Scientific American covers the migratory stopover of Sandhill Cranes (Grus canadensis) along the Platte River in Nebraska. Good set of references, too:

For more information about the migration, browse these Web sites: www.ngpc.state.ne.us/wildlife/migrate/intro.htm, http://platteriver.unk.edu and www.rowesanctuary.org. In addition to Victor Emmanuel Nature Tours, multiday trips are often organized by Wings and Field Guides. For general information on cranes, see the International Crane Foundation's site. Among the many helpful books are The Birds of Heaven, by Peter Matthiessen; Crane Music, by Paul A. Johnsgard; The Cry of the Sandhill Crane, by Steve Grooms; and Birding Crane River, by Gary R. Lingle.
