Description Shorebirds can be found on the shores of or in marshes and grasslands near, the ocean, rivers, or mountain lakes. These mighty migrators travel back and forth between summer breeding grounds and non-breeding grounds. They have special rest stops during their migration where they eat and rest for the remainder of their trip. They may dig a nest into the shore's sand, mud, or rocks. Each shorebird has a unique bill to find its specific food. Learn how these fascinating birds are alike and different in this latest title in the Compare and Contrast series.
