Whooping Cranes are mainly creatures of the wetlands and fly into dryer uplands along major river valleys including the Platte, Brazos, Red, and Mississippi Rivers. The migrating Whooping Crane change diet as they move to other locations. When Whoopers live in high elevation wetlands such as those found at the Great Salt Lake (Utah-Nevada) or Mono Lake (California), their diets consist mostly of crustaceans like blue crabs, vegetation, and fish. But when winter in lowland estuaries such as San Antonio Bay (Texas), Louisiana's Barataria Basin, or Western Florida Everglades, a large portion of their food is sea bass from commercial saltwater fisheries which they catch by diving from great heights.
