Yeah I use it almost everyday. I've gotten to where I frequently recognize new birds. I don't talk about it much because I haven't fully come to terms with entering a bird watching phase of my life, but occasionally I'll say something like "Oh that Northern Flicker is back" and my wife will be totally confused. We live in Brooklyn near Prospect Park and have a backyard so we get a pretty wide range of birds.
I'm on the other side of the continent and a Northern Flicker is the loudest bird outside my window right now :)
