While song sparrows are extremely easy to capture at least in most places here, I haven't taken a picture of one since I started taking bird photos in 2003. I wanted to have at least one for the archives. Our Pacific Northwest flavor is decidedly dusky, which matches the sky a good deal of the time. It would seem that there are several species that have this trait on the rainy side of the mountains like downy woodpeckers and of course dusky grouse.
