The Mammals Of Illinois And Wisconsin PDF Download

Excerpt from The Mammals of Illinois and Wisconsin, Vol. 11 The present work includes, so far as known, all the living mammals which have been found in Illinois and Wisconsin, and gives descriptions of the various species and subspecies, with more or less of their life histories, together with maps illustrating their supposed geographical distribution. To increase its usefulness, brief synopses of all the known species and subspecies, belonging to our genera, which occur in eastern North America, are given and their distribution is indicated in the maps. While it is hoped it will prove a useful book of reference for the specialist, it has been written with special regard to the needs of the layman, for, without departing from scientific lines, I have endeavored to make it as non-technical and popular in character as a serious consideration of the subject would permit. With this object in view, for the purpose of simplifying identification of the various species belonging to a family, they are, wherever possible, arranged in the keys in groups based upon external characters which may be readily recognized by the lay reader, often regardless of their genera and not serially in their proper order as they are treated in the text. In a few cases, however, positive identification of a species depends upon dental characters which, while usually well-marked, are sometimes (as among the Shrews) too small to be seen with the naked eye. The student should therefore provide himself with a strong lens for the purpose. At the present time 94 species and subspecies of mammals have been recorded from Illinois and Wisconsin, and probably several more will in time be added to the list. Such species as Dyche's Harvest Mouse (Reithrodonlomys dychei), Little Meadow Mouse (Microtus minor), Woodland Jumping Mouse (Nap ozapus insignis), Prairie Spotted Skunk (Spilogale interrupta), Big-eared Bat (Corynorhinus macrotis) and Free-tailed Bat (Nyctinomus depressus), have been taken in such nearby localities that there is little doubt that most of them will ultimately be found to occur within our limits. Those who desire to study our mammals will be interested to learn that a considerable number may still be found in a wild state in the public parks of Chicago.
