Auto Tour Stop #12: Grasslands for Ducks . Though usually associated with water, ducks like mallards and blue-winged teal are dependent on grasslands like the one on your right for nesting each spring. The cover in these areas is maintained through periodic planting, burning or re-seeding with dense nesting cover. Also check the rock point in Pine Lake on your left (next pictures) where peligans, cormorants, gulls, terns or trumjpeter swans can sometimes be seen loafing.
