AVAILABILITY OF STOPOVER HABITAT FOR MIGRANT WHOOPING CRANES IN NEBRASKA
Four stratified random samples of 512 National Wetland Inventory (NWI) maps within the central Nebraska portion of the Wood Buffalo-Aransas whooping crane (Grus americana) migration corridor were used to evaluate the availability of wetland roost sites. Wetlands were eliminated as potential roosts i...
