If a bird calls in a forest, or a swamp, or a grassland, and no birder is there to hear it, did that vocalization really happen? The birds sounds we miss contain so much information about bird behavior and populations, wouldn’t it be useful if we could hear those sounds surreptitiously. That’s the work of Tessa Rhinehart, a researcher, birder, and mathematician at the University of Pittsburgh who trains computers to identify birds for science and conservation.  Also, birders in Nova Scotia get a car company to overhaul their commercial.  Subscribe to the podcast at Apple Podcasts, Stitcher, and Google Podcasts, and please leave a rating or a review if you are so inclined!
