following 12 priority research objectives for data analyses were identified: 1) Characterize habitat for <br />palustrine and riverine roost and feeding sites. 2) Determine behavior and use patterns for roost and <br />feeding sites using individually- marked cranes. 3) Determine migration patterns of individually- marked <br />birds. 4) Determine use patterns of family units versus individual and non - family groups. 5) Determine <br />use patterns for fall versus spring. 6) Determine use patterns for palustrine versus riverine habitat <br />throughout the flyway. 7) Determine climatic influence on palustrine versus riverine use. 8) Determine <br />use patterns by state and region throughout the flyway. 9) Determine temporal changes in use patterns — <br />year to year and over time. 10) Determine influence of other species, i.e. sandhill cranes (Grus <br />canadensis), waterfowl, and shorebirds, on use patterns. 11) Assess site evaluation data against NWI <br />classification. 12) Assess length of stay regionally for fall versus spring migration. <br />The goal of this project is to conduct a comprehensive analysis of existing observational and site <br />evaluation data for habitat use by whooping cranes through the migration flyway from Texas to North <br />Dakota. This report provides a summarization of the sightings locations for 1943 -99 and habitat <br />description information for 1977 -99. We provide recommendations on data needs, limitations, and survey <br />methods for future monitoring of whooping cranes during migration. <br />
