The Aransas-Wood Buffalo population of whooping cranes (Grus americana) declined to near extinction by the 1940s. Starting during winter 1950 - 1951, annual aerial surveys were conducted to observe and record the number of whooping cranes wintering on Aransas National Wildlife Refuge (NWR) and surro...
