Birding Resources


IBird Pro – This is an interactive field guide that includes pictures and bird calls. The app allows you to search by first, last or family name which makes it easy for anyone to use. Also includes a “similar” feature that allows you to easily identify birds. The application can be downloaded for a minimal cost.

National Geographic Birds: Field Guide – A comprehensive field guide for over 900 species of birds. Good for all birding experience levels.


National Geographic Field Guide to the Birds of North America – This provides information about the bird, a picture of the bird and range maps on the same page. It is very easy to use and covers the whole country.

The Sibley Field Guides – There are different versions available; all are great. The Field Guide to Eastern North America and The Sibley Field Guide are among the most complete bird identification books.

Peterson Field Guide to Eastern Birds – The old standby. It is easy to use. This guide categorizes by orders of birds. It offers good illustrations highlighting distinguishing features. Range maps are in the back of the book. There are other versions of this book: Western Guide, Birds of Texas, etc.

Birds of Illinois by Stan Tekiela – A good resource for birds located in Illinois. Birds are organized by color. It includes nice photos and gives additional information about the bird (i.e., nests, eggs, etc)

Sparrows and Finches of the Great Lakes Region and Warblers of the Great Lakes Region by Chris Earley – Nice supplemental books for further identifying certain birds. They provide close-up photos and general information about each species. There are other books in this series.

The Sibley Guide to Bird Life and Behavior – A favorite on many bookshelves. This is the book to use as a reference when you want to know more about bird behavior. For example, if you want to know how many eggs and what color eggs a particular bird lays, the Sibley Guide provides that information. It also provides information on migration patterns.

The Birder’s Handbook by Paul Ehrlich, David Dobkin, and Darryl Wheye – This is not so much an identification book but a great resource for the natural history of birds. There is lots of information condensed into this book to help you expand your birding experience.
