Seen and Heard 

Colorado 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 CU 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 Colorado Birds, who teaches writing and rhetoric at CU. The book’s companion website is petersonbirdsounds.com. Submit your responses to editor@colorado.edu.
