Who's that singing? As fall migration arrives, apps that ID birds by sound have taken off
I was sitting in solitude earlier this summer in an Adirondack chair in my backyard, when I realized I wasn't as alone as I'd thought. Thanks to the app I'd just downloaded on my phone — the popular and free Merlin Bird ID — I learned just from listening that I was surrounded by more than a dozen species of birds. Where before I had simply heard birdsong, I now realized how rich the variety was in that single moment.
