Minnesota Birds was first published in 1975.This is an indispensable guidebook for birders in Minnesota, both amateur and professional, and a useful reference work for naturalists elsewhere as well. It provides information about each of the 374 species sighted in the state -- in what seasons they are present, how abundant they are, and in what areas they are likely to be found. The account for each species is divided in three sections: migration, including distribution, abundance, and dates; summer season, including breeding range and nesting records; and winter season, including distribution and abundance. Both authors are highly experienced ornithologists. Janet C. Green lives in Duluth and does much of her fieldwork on the North Shore of Lake Superior and in the northwoods. Robert B. Janssen, who lives in Chanhassen, is former editor of The Loon, the journal of the Minnesota Ornithologists’ Union, and has done fieldwork throughout the state. Harrison B. Tordoff, former director of the James Ford Bell Museum of Natural History at the University of Minnesota, writes a foreword.
