January 13th Lecture Series at 7p.m at Horicon Marsh International Education Center Ron Gatti: Duck Survival and Production in Wisconsin Blue-winged teal were the most abundant breeding duck species in Wisconsin until they began a sharp population decline in the 1970s, which continues today. The WDNR is trying to determine the cause of the decline by estimating vital rates of survival and production via radio telemetry. Is the problem in low survival of eggs in nests, ducklings in broods, or adult hens during the breeding season? Through the study we will be testing our management assumption that teal recruitment is limited by the abundance of grasslands. We will also be looking for correlations between teal vital rates and habitat features that we can manage.
