A "thunderstorm map" of pheasant nesting success in a township in Kossuth county, Iowa. High nesting success areas are shown in bright yellow. Notice that nest success in large patches of planted cover (three 160-acre blocks in the lower part of the picture) varies within the patch, depending on the surrounding landscape. Notice that predicted success in some isolated road ditches actually is above average.
