"A Birder's Guide to North Dakota" by Kevin J. Zimmer is a comprehensive guidebook written in the late 20th century. The book serves as a resource for birdwatchers and ornithology enthusiasts interested in the diverse avifauna of North Dakota. It covers various habitats, notable bird species, and prime locations for birdwatching across the state, making it an essential reference for both residents and visitors. The opening of the guide aims to establish its purpose and acknowledge the contributors who aided in its creation. Zimmer emphasizes the vastness of North Dakota and the importance of exploring its lesser-known natural beauty, which is home to many bird species. The initial sections introduce the state’s range of natural habitats—from wetlands and prairies to river systems—and hint at the historical significance of birding in the region, mentioning notable figures like John James Audubon and Theodore Roosevelt. The preface and introduction effectively set the stage for a detailed examination of the state's bird species and the best locations for birdwatching in subsequent chapters.
