Where do the Chesapeake Bay's sea turtles come from in the summer, and where do they go in winter? Where do swans come from when they arrive in the region in November? And why do fishermen and sailors consistently see monarch butterflies out over the open Bay in late summer? This book answers these questions and enables those who love the Bay to tune in to its natural events. The fishing enthusiast may discover things that help him or her catch more bluefish or white perch; the bird-watcher and the hiker will learn when to look for the return of the ospreys in the spring and of the geese in the fall. The canoeist will discover when to look for wild marsh flowers in a favorite tidal creek. The book's natural history sketches cover the upper ends of the Bay's rivers down to the mouth.
