There is a reason Duluth is one of the most famous places in the country to watch birds of prey. Hawks, eagles, and falcons heading south for the winter do not like to cross large open water, so when they reach the north shore of Lake Superior they turn and follow the coast, and everything funnels down to the western tip of the lake, right over the city.
The result, every September, is one of the great wildlife spectacles in North America. On the biggest days, tens of thousands of broad-winged hawks ride the thermals overhead in swirling "kettles," sometimes so many that the count runs past a hundred thousand birds in a single day. Hawk Ridge, on the bluff above town, has been logging it for decades.
This map is those raptors, thick along the shoreline and the ridge. Sharp-shinned hawks are the most numerous over a whole season, but the broad-wings are the show, and their calendar is basically right now. Later in the fall the cast changes over to eagles and the occasional goshawk.
If you go, get up to the ridge on a day with a northwest wind behind a cold front. That is when the sky fills.
