Well, this is me now:

It started a few years ago when our firstborn got into our copy of The Little Book of Backyard Bird Songs that plays a dozen different bird calls. Then one day while on a walk through our local park, I heard a call that I recognized from the book, so I knew right away: red-winged blackbird!

More recently I started using the free Merlin Bird ID app, which identifies birds based on their calls and has made me much more attuned to hearing new ones as we walk. According to that, our neighborhood is full of cardinals, robins, house sparrows, mourning doves, red-winged blackbirds, grackles, white-breasted nuthatches, woodpeckers, and lots of other avian delights.
