At the end of September, my friend Shawn Conrad and I saw several groups of Bonaparte’s Gulls feeding along the shore of Lake Winnibigoshish (often referred to as Winnie.) These birds are migrating to their winter home along the coasts of the United States. Most people are surprised to learn that these gulls nest in trees. They choose conifer trees near boreal lakes and marshes in Alaska and across the middle of Canada. This photo and the next two were taken at Denny’s Resort in Cass County, MN.
