Abstract

We will investigate the ecology, distribution, and abundance of waterfowl and other wetland-associated birds in relation to habitat characteristics along and nearby the Illinois and Mississippi rivers; waterfowl, marsh birds, shorebirds, and other wetland-associated birds in wetlands and deepwater habitats statewide; investigate the ecology and distribution of shorebirds in relation to habitat characteristics in central Illinois and Canada geese in northeastern Illinois; and summarize and distribute our results. 1) Inventory abundance and distribution of waterfowl and other waterbirds (≥10 species and guilds) during autumn (September–January) and spring migration (February–April) at a minimum of 30 sites along and nearby the Illinois and central Mississippi rivers, 2) Evaluate postbreeding ecology of wood ducks (Aix sponsa) by radiomarking up to 100 individuals during late summer and autumn in and nearby the central Illinois River Valley, 3) Contribute to efforts to study population ecology of lesser scaup (Aythya affinis) and canvasback (Aythya valisineria) by trapping and leg-banding a minimum of 1,000 individuals during spring migration in the Illinois River Valley, 4) Continue to investigate the ecology of green-winged teal (Anas crecca) and gadwall (Mareca strepera) by radiomarking a minimum of 40 individuals of each species during spring migration in and nearby the central Illinois River Valley, 5) Continue habitat quality evaluations of ≥50 wetland and deepwater polygons during spring, summer, and early autumn for migrating dabbling ducks, breeding wetland birds, and migrating shorebirds, respectively, in Illinois, 6) Evaluate waterfowl harvest and hunter success at state-managed waterfowl hunting areas in relation to food abundance and quality on nearby managed sanctuaries in the Illinois River Valley, 7) Investigate movements and home range size of ≥10 Canada geese (Branta canadensis) during winter in and near the Greater Chicago Metropolitan Area (GCMA) of Illinois, 8) Inventory abundance and distribution of shorebird guilds during spring (April–May) and autumn (July–August) migration at ≥20 sites along and nearby the central Illinois River Valley and other areas in central Illinois, 9) Distribute results and findings to site managers and biologists of the Illinois Department of Natural Resources (IDNR) and other state agencies, the Mississippi Flyway Technical Section, the Upper Mississippi River and Great Lakes Region (UMRGLR) Joint Venture, the U.S. Fish and Wildlife Service, other scientists and collaborators as requested, and the general public through oral presentations, popular articles, technical reports, and peer-reviewed publications; make recommendations for future wetland management practices and research needs based on results and related research; contribute to regional wetland and waterbird conservation planning efforts during the project period as appropriate and requested.
