"There and back again: Avian navigation and migration" was a program presented by Michael P. Lombardo on 15 October 2024 at Loutit District Library, Grand Haven, Michigan. The program was sponsored by the Owashtanong Islands Audubon Society and the Muskegon County Nature Club. Description: Many species of birds in the temperate zone are long-distance travelers that make twice yearly journeys between their breeding and wintering grounds. This program will review the costs and benefits to birds of migration, some of spectacular journeys made by some birds, and the various ways that birds find their way during migration including following other birds, using land features and coastlines as guides, using the position of the sun if they travel by day or the stars if they travel at night, the geomagnetic field of the earth, odors, and inherited navigation.
