First a couple caveats - I can give you a long list of plants but I have limited experience attempting to grow these from seed. Secondly, some plants that are native and not invasive can still be fairly aggressive spreaders.
For a start here are some native (to north central North America, not necessarily Ohio) grasses: Schizachryrium scoparium - Little Bluestem, Andropogon gerardii - Big Bluestem, Bouteloua curtipendula - Side-oats Grama, and Sorghastrum nutans - Indian Grass (big, self sows prolifically).
Sources for these and other native seeds include Prairie Moon Nursery in Minnesota, Prairie Nursery in Wisconsin and Ernst Conservation Seeds in Pennsylvania. I believe they all have websites.
Among perennials echinaceas, Rudbeckia maxima (native to south central U.S. but should grow in Ohio), and Ratibita pinnata (also native further south, seeds like mad in my experience) are all popular with seed eating birds but there are many more.
For shrubs and small trees viburnums, hawthorns, aronia, and crab apples are good choices. Birds love amelanchier berries but they will take them long before winter.
