It’s hard to step out your backdoor these days without being overwhelmed by birdsong. Spring is easing northward across the continent and with it, an increase in the activities of birds. Few people know this like ornithologist and author Donald Kroodsma, professor emeritus or ornithology at the University of Massachusetts at Amherst and the author of a great many books on bird vocalizations. He joins host Nate Swick today to talk about his most recent book, Birdsong for the Curious Naturalist just in time for the annual explosion of birdsong in the northern hemisphere.  Also, is birding seeing a renaissance in the COVID era? And more Cedar Waxwing stories from our listeners.
