Å·ÃÀ¿Ú±¬ÊÓƵ is a great place to see — and hear — birds: Some 500 species have been observed here, more than in all but a handful of other states. Can you identify the seven shown here, each photographed at or near Å·ÃÀ¿Ú±¬ÊÓƵ Boulder?

The first three readers to respond with correct species identifications for all seven will receive a copy of Peterson’s Field Guide to Bird Sounds of Western North America (forthcoming in April), by Nathan Pieplow, a former editor of the journal Å·ÃÀ¿Ú±¬ÊÓƵ Birds, who teaches writing and rhetoric at Å·ÃÀ¿Ú±¬ÊÓƵ. The book’s companion website is petersonbirdsounds.com. Submit your responses toÌýeditor@colorado.edu.
