Birds of North-Central Wyoming and The Bighorn National Forest by Helen Downing

Birds of North-central Wyoming and the Bighorn National Forest, by Helen Downing, was originally printed in 1990, and has been out of print for some time. Because of many requests, the Bighorn Audubon Society has generously funded a reprinted edition, available now. The author was interested in documenting the species and general numbers present during the mid- to late-twentieth century. Her intent was to pass this information on to future birders, enabling us to compare historical data with recent trends caused by habitat loss and climate warming. The book is useful to both amateur birders and scientists. It is suitable for amateur birders as a reliable source of information—could this bird be seen here? Is it common or unusual, and in what months and years has it been seen in the past? Scientific birders will appreciate it because is a source of baseline information.
