This book is a collection of photographs of owls taken in Wisconsin, Northern Minnesota and Arizona. Many of the images were taken during the Great Gray Owl irruption of 2004-2005. As many as 15 great gray owls could be observed in a single afternoon during the irruption. A few great gray owls even migrated as far South as Southern Wisconsin, with one great gray owl spending a week within a few miles of my home in DeForest.
