MORTALITY IN FLEDGED WHOOPING CRANES OF THE ARANSAS/WOOD BUFFALO POPULATION
A total of 1,893 whooping cranes (Grus americana) overwintered at Aransas National Wildlife Refuge from 1950 through spring 1987. Winter losses (dead and disappeared) amounted to only 1.3% of the population, but 3.7% of the juveniles. About 19% of the annual losses occurred in the wintering area whe...
