Satellite MapSatellite photo of the lower Chesapeake Bay area, showing the diverse geographic features and illustrating how birds traveling down the Atlantic coast during late summer and fall migration become concentrated at a critical stopover site at the tip of the Eastern Shore of Virginia, near Kiptopeke. Some birds cross the 30 kilometer stretch of water to the Virginia mainland shore, while others return north to search for an alternate route. During spring migration, birds generally travel up the western shore of Chesapeake Bay. First Landing State Park, in the midst of a huge urban area, is an important spring migration site.
