This newest addition to Iowa's popular series of laminated folding guides-the twenty-eighth in the series-illustrates the thirty-eight species of warblers that occur in the Upper Midwest states of Minnesota, Illinois, Nebraska, Kansas, North Dakota, South Dakota, Iowa, Indiana, Michigan, Ohio, and Wisconsin. For each species, artist Dana Gardner provides length, range, and habitat; he illustrates male, female, and immature birds where plumage varies; and he includes birds similar to warblers such as kinglets and vireos.
