This unfortunate sparrow flew into a window. I'm fairly sure I heard it happen and found the little bird, still, but unmarred, on my porch just moments later. A small heartbreak. If I'd been a nineteenth century leisure class naturalist, I'd have made more detailed studies. I'm half sorry I didn't. It's not often that such an exquisite model just falls into one's hands.
White-throated sparrows have a distinctive, evocative call. If you live in North America, you may already know it. If you'd like to hear it, visit this wikipedia page and click on the audio file under Song and Calls.
