From Cornell Lab of Ornithology: “Bird migration capitalizes on seasonal surges in protein and nutrients—like insect hatches and fruiting seasons—that are needed for breeding. These globe-spanning voyages might seem extreme, but most migratory birds don’t make their entire journey in one trip. Instead, they play a game of hemispheric hopscotch, skipping from one migratory stopover site to the next, like a family minivan hitting rest stops on a cross-country road trip.”
From the map you can see that the western Lake Erie basin lights up for spring and fall, but most of Ohio important during fall migration.
