Mammals of Washington, Volume 2 University of Kansas Publications Museum of Natural History

"Mammals of Washington, Volume 2" by Walter Woelber Dalquest, is a mid-20th century science book about the mammals of Washington state, explaining where they live, their surroundings, and their origins, all taking into account the area's geography and weather. It's a great source for nature lovers and animal scientists who want to learn about the unique types of mammals that have grown in this diverse environment. The beginning of the book prepares readers for a thorough look at Washington's mammals by talking about the state's geological past and how glaciers affected the animals that live there. It points out that many of the mammals living in the state today came relatively recently, after the glaciers disappeared. The ideas of life zones and areas with similar physical features are presented to show how these things affect where different mammal species are found and how they are classified, which builds a base for later chapters that explore specific species and where they live in different ecological zones.
