Hope is the thing with feathers

Hope is the thing with feathers: Listening to birdsong is really good for you. But many of us live in urban environments where birdsong is a scarce resource, so you might consider opening up this YouTube audio clip, or this one, or this one, and just let those little birdies serenade you while you work at your computer, or savor your morning coffee, or do your household errands. It's good for the soul.
