Renesting Decisions and Annual Fecundity of Female Dickcissels (Spiza Americana) in Illinois

T.-Renesting decisions and annual fecundity are crucial for interpreting other demographic information, yet are infrequently reported. We used radiotelemetry to monitor female Dickcissels (Spiza americana) throughout the 1999 and 2000 breeding seasons in south- eastern Illinois. Overall fecundity (regardless of whether females remained in the study area throughout the breeding season) was 0.61 ? 0.13 female fledglings per year. Of females that re- mained within the study area, 94% fledged young (1.25 ? 0.15 female fledglings per year). Most females (62%) that experienced nest failure emigrated from the study area (moved \u3e10 km) in 2.8 ? 0.6 days; others (36%) initiated subsequent nests in 8.5 ? 0.8 days. After fledging \u3e1 young, 95% of females ceased breeding for the season. Successful and failed nest sites were indistin- guishable on the basis of vegetative characteristics. Moreover, replacement nests had similar vegetative characteristics and were similar distances from habitat edges, compared with initial nests, which suggests that female Dickcissels do not or cannot improve nest-site characteris- tics in response to nest failure. We observed two behaviors unusual in female Dickcissels: one bird that fledged two broods in one season, and the return of five females banded in 1999 to the study site in 2000

Data Stewardship Workshop Report, March 2016, Therkildsen Field Station at Emiquon

The Nature Conservancy is a science-based organization that makes significant investments in research and monitoring of the ecological outcomes and effectiveness of our conservation work. The Illinois Chapter has large and rapidly increasing quantities of data that must be appropriately managed to make the data accessible and to prevent their loss. The purpose of the data stewardship workshop was to design and launch a TNC data stewardship initiative to organize and manage data internally in the near term, and scope future efforts for multi-organization collaboration and coordination. This initiative, focusing initially on the Emiquon project with data from many sources, including university and agency partners, will inform subsequent data and information stewardship initiatives for other TNC programs.The Nature Conservancy, IllinoisOpe
