Here in the frozen tundra of Minnesota, spring is slowly emerging. Tulips have broken through, crocuses and squills are blooming and, if you're quiet at night, you can hear the first frogs beginning to call.
For me, nothing speaks more of the northwoods and summer than the lively chorus of frogs, toads, crickets and other night insects.
Several weeks ago I enjoyed listening to an NPR broadcast focusing on all these sounds with guest author John Himmelman.
Himmelman's written a book titled "Cricket Radio" about the night's "nature sounds" and what prompts these critters to produce them.
The sounds swept me away with the promise of warm summer nights. Himmelman's voice detailing what I was hearing, and why I was hearing it, was perfect.
Here's the "Cricket Radio" site where you can listen to the NPR program and learn more about Himmelman's book.
