A flock of nighthawks circle an area over Lake Superior Monday, below the Lakeside neighborhood of Duluth. Avian ecologist Steve Kolbe guessed the nighthawks had found a food source in the area and were filling up before continuing south. The sky that night was filled with mayflies and other smaller insects including monarchs, which are poisonous to nighthawks.
