Author and naturalist Larry Weber observes the final week of summer, noting the warmer temps (10 degrees above average for September!). The leaves are already starting to change: Maples, sumacs, dogwoods are turning red, but so are Virginia creeper and poison ivy. Yellow leaves to look out for are the ash, birch and poplar trees. Birds are migrating – this is "hawk weekend" in the Duluth area. Geese and cranes are in motion, as are the warblers, thrushes and flickers, among others.
