Where two numbers occur in a column, <br />the one in parenthesis is the original count and the second is the adjusted number as <br />explained in Boyce (19871. The 1945 count at Aransas NWR and vicinity was 14 and 3, <br />but 22 adult-plumaged birds returned to the refuge in the winter of 1946. Consequently, it <br />is evident that sonie birds were not counted in 1945. <br /> <br />Saskatchewan, in 1922 (Hjertaas 1989), and the last reported reproduction in the <br />nonmigratory Louisiana population occurred in 1939 (Lynch 1956, Gomez 1992). The <br />nesting area of AWP was discovered in 1954 in WBNP, Northwest Territories, Canada <br />(Figure 1 I, and this population is the only historical one that survives. <br /> <br />In the 19th century, there were several migration routes. The two most important ones <br />(Allen 1952:1031were n.. .those between Louisiana and the nesting grounds in Illinois, <br />Iowa, Minnesota, North Dakota, Manitoba, and the other from Texas and the Rio Grande <br />Delta region of Mexico to nesting grounds in North Dakota, the Canadian Provinces, and <br />Northwest Territories. n A route through west Texas into Mexico apparently followed the <br />route still used by sandhill cranes, and it is believed the whooping cranes regularly travelled <br />with them to wintering areas in the central interior highlands region (Allen 1952), <br />
