Northern goshawks are a species of conservation concern, in part because of their purported association with mature forest cover types. However, these habitat associations are not well documented in the Upper Midwest, where most information on goshawk populations is derived from monitoring nests. We modified an existing protocol to estimate occupancy of northern goshawks in the western Great Lakes region, and conducted a field survey in 2008 following that protocol. Our results suggest that goshawks are widely distributed at relatively low densities across the western Great Lakes region, and use more mature forest stands for nesting.
